TMS320F28062PZT is a 32-bit real-time microcontroller from Texas Instruments' C2000 Piccolo family. It pairs a 90 MHz C28x core with a floating-point unit (FPU), a control-law accelerator (CLA), and a Viterbi/complex-math unit (VCU) to handle digital power and motor-control algorithms without choking the CPU. The "PZT" suffix means it ships in a 100-pin LQFP (14 mm x 14 mm) and is rated for the industrial temperature range of -40 degC to +105 degC.

In plain terms, this is the chip TI designed for engineers who need DSP-like math performance in a microcontroller footprint and budget. It does not have the raw clock speed of an ARM Cortex-M7, but the CLA and VCU let it offload control loops so the main CPU stays free for communication and state management. That architecture is why solar-inverter and motor-drive designers keep coming back to the F2806x line even as newer parts appear.

A few numbers deserve extra attention. The 3.46 MSPS ADC sample rate matters if you are running fast current loops in a motor drive; slower ADCs force you to interpolate or accept higher latency. The 8 HRPWM channels give you roughly 150 ps edge resolution, which is useful for digital power supplies where nanosecond jitter shows up as output ripple. And the CLA is not just a marketing bullet -- it runs control code in parallel with the C28x core, so your PID or field-oriented-control loop can execute at 20 kHz while the main CPU handles Modbus or logs data to USB.

The PZT suffix maps to a 100-pin LQFP with 0.5 mm pin pitch. The package body is 14 mm x 14 mm, which is large enough to route comfortably on a four-layer PCB but small enough to fit into compact motor-drive or power-supply boards.

Pin groups break down roughly like this:

• Power and ground -- Multiple VDD and VSS pins distributed around the package to keep ground bounce low when PWM edges switch fast.

• ADC inputs -- AIO and analog input pins grouped on one side of the package to keep analog traces away from noisy digital clocks.

• PWM outputs -- ePWM and HRPWM pins clustered so you can route gate-drive signals with similar trace lengths.

• Communication -- SCI, SPI, I2C, CAN, and McBSP pins placed with flexibility in mind; most can be remapped through the GPIO mux if your layout needs a different pinout.

• JTAG debug -- Standard TDI, TDO, TMS, TCK, and TRST pins for XDS110 or XDS200 emulators.

• USB -- USB 2.0 full-speed device/host pins with internal PHY, so you only need a connector and a series resistor.

One practical layout tip: the analog reference pins (VREFHI / VREFLO) need clean routing. Do not run them parallel to PWM traces, and place the reference capacitor as close to the package as your assembly house allows. A noisy reference shows up as ADC codes drifting, and that can destabilize a current-control loop.

The F28062 is not just a fast MCU. It is a fast MCU with peripherals arranged for closed-loop control.

The CLA: A Second Core for Control Loops

The control-law accelerator is a 32-bit floating-point processor that can read ADC results, run a control algorithm, and update PWM duty cycles without interrupting the main C28x CPU. That matters because in a motor drive or digital power supply, your control loop needs to run at a fixed period -- say 10 kHz or 20 kHz -- and any jitter in that period turns into torque ripple or output noise.

With the CLA handling the loop, the C28x CPU is free to run slower tasks like communication stacks, state machines, or logging. You can think of it as an asymmetric dual-core setup where one core is dedicated to real-time math.

The VCU: Math Acceleration for Specific Algorithms

The Viterbi/complex-math unit speeds up three operations that show up often in power electronics and communications:

• Complex multiplies -- Used in FFT-based harmonic analysis or certain sensorless motor-estimation techniques.

• Viterbi decoding -- More relevant if you are using power-line communication (PLC) modems on the same board.

• CRC -- Hardware CRC is handy for validating firmware images or serial protocol frames without burning CPU cycles.

ADC and PWM Synchronization

A detail that separates professional motor-drive designs from hobby-level ones is ADC-PWM synchronization. The F28062 can trigger ADC conversions exactly in the middle of a PWM period, when the switching noise is lowest. That gives you cleaner current samples, which means cleaner control. The SOC (start-of-conversion) triggers are configurable per ePWM module, so you can stagger sampling across multiple phases if you are building a multilevel inverter or a multi-axis servo.

TI markets the F2806x family for five broad areas. Here is how the F28062 fits into each one in practice.

Industrial Motor Drives

The F28062 has enough PWM channels for a three-phase inverter plus brake chopper, and the CLA can run a sensorless field-oriented-control (FOC) loop at 10-20 kHz. It does not support InstaSPIN-FOC (that requires an F28068F or F28069F), so you will write or port your own estimator. For mature motor-drive teams that already own FOC code, the F28062 is an attractive cost-down option.

Solar Inverters and Digital Power

Solar micro-inverters and DC/DC converters benefit from the HRPWM resolution. When you are pushing 99 percent efficiency, even small timing errors in the gate drive turn into watts of heat. The 12-bit ADC is sufficient for voltage and current sensing at the bandwidths typical of residential solar, and the USB port gives you a convenient way to log performance data during field commissioning.

Electric Vehicles and Transportation

In EVs, the F28062 shows up in auxiliary inverters -- pumps, fans, and compressors -- rather than the main traction inverter. Traction drives usually need more Flash (256 KB or more) and safety certification (ISO 26262), which pushes designers toward the F28069 or newer F2838x families. But for a 5 kW auxiliary pump, the F28062 has enough headroom.

Appliance and Building Automation

HVAC compressors, washing-machine motors, and dishwasher pumps are price-sensitive applications where the F28062's single 3.3 V supply and compact LQFP package help keep the BOM lean. The integrated analog comparators can trip PWM fault inputs directly, so you can build over-current protection with minimal external components.

Test and Measurement

The 3.46 MSPS ADC and parallel CLA make the F28062 useful for data-acquisition front ends that need real-time preprocessing. Think power-quality analyzers or vibration monitors where you want to compute an RMS value or FFT bin before sending summarized data upstream.

The F2806x series spans eight part numbers, and the differences come down to memory size, InstaSPIN support, and a few peripheral variations. Here is the landscape:

Wait -- that table looks flatter than it should. The reality is that TI has released many F2806x variants with small memory and peripheral tweaks, but the meaningful forks for a designer are these:

1. F28062 through F28067 -- All sit at 128 KB Flash and 52 KB RAM. Minor differences in eCAP or eQEP counts exist, but for most designs the parts are interchangeable within this block.

2. F28069 -- Doubles Flash to 256 KB and RAM to 100 KB. Choose this if your control algorithm, lookup tables, and communication buffers do not fit in 128 KB.

3. F28068F / F28069F -- Add InstaSPIN-FOC, TI's sensorless motor-control library that auto-tunes itself. If you need to spin a PMSM or BLDC motor without encoders and you do not want to write an estimator from scratch, these are the parts to target.

4. F28068M / F28069M -- Add InstaSPIN-MOTION for position-control applications like servo drives or robotic joints.

So where does the F28062 fit? It is the entry-level sweet spot in a line that already targets cost-sensitive real-time control. You get the full FPU/CLA/VCU compute stack, a rich peripheral set, and USB -- but you skip the InstaSPIN license fee and the larger memory die that pushes the F28069 into a higher price bracket.

Not yet, but the clock is ticking. TI has not issued an NRND (Not Recommended for New Designs) notice for the F28062, and the part is still listed as Active on TI.com. However, the company has been steering new designs toward the F28004x generation for several years.

The F280041 -- the closest modern equivalent -- runs at 100 MHz (up from 90 MHz), adds a trigonometric math unit (TMU) that accelerates sin/cos/atan operations, and includes a programmable gain amplifier (PGA) and sigma-delta filter module (SDFM) that the F28062 lacks. Those additions matter if you are using isolated current sensors or resolver-to-digital converters.

Does that make the F28062 a bad choice today? Not necessarily. If you have existing code written for the F2806x, the F28062 lets you reuse it with minimal porting. If your BOM is tight and you do not need the TMU or PGA, the F28062 may still be the cheaper option. And if you are maintaining a legacy design, the part remains available through distribution.

The risk is long-term availability. TI typically keeps a part Active for 10-15 years after introduction. The F28062 launched around 2011, so by the late 2020s it could move to NRND or LTB (Last Time Buy). If you are designing a product with a 10-year production life, you should either qualify the F280041 as a second source now or plan a migration path.

If the F28062 is not quite right -- or if you are worried about longevity -- here are five directions engineers typically explore:

1. Stay in the family: F28069

Same pinout (in LQFP-100), same peripherals, double the memory. If your code is pushing 100 KB of Flash and you are out of RAM, this is a drop-in upgrade. The price jump is usually modest compared to the engineering cost of switching families.

2. Upgrade to InstaSPIN: F28069F or F28069M

If you are building a motor drive and you want TI's auto-tuning sensorless stack, the F28069F (FOC) or F28069M (motion) are the parts to evaluate. InstaSPIN saves months of estimator tuning, but it locks you into TI's software licensing model.

3. Move to the next generation: F280041

The F280041 is TI's current recommendation for new digital-power and motor-control designs. It is faster, has more modern analog integration, and will stay in production longer. The downside is a different pinout and some register-map changes, so plan for a PCB spin and firmware port.

4. Cross-vendor alternatives: STM32G4 or STM32F3

If you are open to leaving the C2000 ecosystem, STMicro's STM32G4 series offers similar FPU and motor-control peripherals at competitive prices. The tradeoff is ecosystem lock-in: TI's C2000WARE, Fast Current Loop library, and motor-control GUI tools do not translate to ST.

5. Higher-end C2000: F2838x or F28003x

For designs that outgrow the F2806x entirely -- more Flash, Ethernet, functional safety -- the F2838x or newer F28003x families are the natural next step. These are not replacements for the F28062; they are the landing zone when your product line grows up.

TI has invested heavily in tooling for the F2806x line, which is one reason engineers stick with it despite newer silicon.

C2000WARE is the software stack you will download first. It includes device drivers, example projects for every peripheral, and math libraries optimized for the C28x and CLA. The examples are not toy demos -- they include complete motor-control projects with FOC loops, ADC synchronization, and fault handling.

Code Composer Studio is TI's Eclipse-based IDE. It is free and supports real-time debugging with graphing tools that plot ADC samples or PWM waveforms while the chip runs. If you prefer command-line builds, the compiler is also available as a standalone toolchain.

LAUNCHXL-F28069M is the evaluation board most teams start with. It is a LaunchPad-format board with an onboard XDS110 debugger, USB device and host connectors, and breakout headers for all major peripherals. Even though the board carries an F28069M, the code ports directly to the F28062PZT with only memory-size changes.

Does the F28062 support InstaSPIN-FOC?

No. InstaSPIN-FOC requires an F28068F or F28069F (or their M variants for motion control). The F28062 has the CLA and FPU, but TI's InstaSPIN libraries are licensed only on parts with the "F" or "M" suffix.

Can I use the F28062PZT for functional-safety applications?

The F28062 is classified as "Functional Safety Quality-Managed," which means TI followed an internal quality process but did not certify it to ISO 26262 or IEC 61508. For automotive or safety-critical industrial designs, look at the F2806x-Q variants or the newer F28003x family with dedicated safety features.

What is the difference between PZ, PZT, and PZP packages?

• PZ = standard LQFP-100, -40 degC to +85 degC (commercial temperature).

• PZT = standard LQFP-100, -40 degC to +105 degC (industrial temperature).

• PZP = HTQFP-100 with PowerPAD thermal pad, -40 degC to +105 degC. Choose PZP if you are driving the core hard and need better heat dissipation.

Is the F28062 pin-compatible with the F28069?

In the same package (LQFP-100), yes. The pin functions are identical, so you can swap the F28062 for an F28069 on the same PCB if you later need more memory. Just update your linker command file to account for the larger Flash and RAM.

How much does the F28062PZT cost?

Pricing varies by volume and distributor, but in small quantities (1-100 pieces) expect to pay roughly $8-12 USD. The F28069 is typically 20-30 percent more expensive. For volume pricing, contact your TI or distributor FAE.

Can the CLA run code independently of the CPU?

Yes, that is its purpose. The CLA has its own program RAM and data RAM, and it can trigger off ADC end-of-conversion or ePWM events. It runs in parallel with the C28x CPU, so your control loop executes with deterministic timing regardless of what the main CPU is doing.

What IDE and compiler does TI recommend?

Code Composer Studio with the TI C2000 compiler. GCC for C2000 exists as a community project, but TI's compiler produces better-optimized code for the C28x and CLA. For production work, stick with the TI toolchain.

The F28062PZT is available through major distributors like Digi-Key, Mouser, and Arrow, as well as regional distributors in Asia. Lead times vary; as of 2026, standard industrial-grade parts are generally in stock, but it is worth checking availability before you finalize a board design.

If you are looking for hard-to-find or end-of-life C2000 parts, WellLinkChips stocks a wide range of TI MCUs and can support BOM consolidation and shortage sourcing. You can check real-time inventory or submit an RFQ directly.
