The TMS320F28062PZT belongs to Texas Instruments' C2000™ family of microcontrollers, a series specifically engineered for demanding real-time control applications. Housed in a 100-pin PowerPAD™ thermally enhanced thin quad flatpack (HTQFP), this device combines a high-efficiency 32-bit CPU core with a rich set of control-oriented peripherals, making it a compelling choice for motor drives, digital power conversion, and advanced sensing systems. This article examines the TMS320F28062PZT across four dimensions: its core architectural features, key electrical and performance parameters, functional capabilities, and typical application domains.

The TMS320F28062PZT is built around the TMS320C28x CPU core operating at 90 MHz, delivering a cycle time of 11.11 ns. The architecture supports 16 × 16 and 32 × 32 multiply-and-accumulate (MAC) operations, along with a 16 × 16 dual MAC configuration. The Harvard bus architecture, atomic operations, and fast interrupt response collectively enable deterministic, low-latency execution of control algorithms.

A distinguishing element of this device is its integrated floating-point unit (FPU), which executes native single-precision floating-point operations. This eliminates the overhead of software emulation for fractional arithmetic, a significant advantage for control loops involving PI regulators, trigonometric transforms, and sensorless observer algorithms.

Beyond the CPU itself, the device incorporates a programmable Control Law Accelerator (CLA). The CLA is a 32-bit floating-point math accelerator that executes code independently of the main CPU. This independence allows the CLA to handle time-critical control tasks—such as current loop regulation—while the CPU manages communication, diagnostics, and higher-level state machine logic. The Viterbi, Complex Math, and CRC Unit (VCU) further extends the C28x instruction set to accelerate complex multiply operations, Viterbi decoding, and cyclic redundancy checks.

The following table summarizes the principal specifications of the TMS320F28062PZT.

The functional design of the TMS320F28062PZT reflects its intended role as a control-centric processor rather than a general-purpose computing device. The peripheral set is organized around the needs of closed-loop power conversion and motion control.

The enhanced pulse-width modulator (ePWM) subsystem provides up to eight modules with sixteen total PWM channels, of which eight support high-resolution PWM (HRPWM). Each module contains an independent 16-bit timer. This configuration is sufficient to drive a three-phase inverter with a brake chopper while retaining spare channels for auxiliary functions.

The analog subsystem includes a 12-bit ADC with dual sample-and-hold circuits, capable of up to 3.46 MSPS across sixteen channels, plus an on-chip temperature sensor. The dual sample-and-hold architecture permits simultaneous sampling of phase currents, a common requirement in field-oriented control implementations.

Communication peripherals include two SCI (UART) modules, two SPI modules, one I²C bus, one McBSP, one eCAN, and USB 2.0 with both device and host modes. Up to 54 individually programmable GPIO pins with input filtering are available. The device also provides a 128-bit security key and lock to protect secure memory blocks against firmware reverse-engineering.

The TMS320F28062PZT is deployed across a range of applications where deterministic real-time response and integrated control peripherals are paramount.

Industrial Motor Drives. The device provides sufficient PWM channels for a three-phase inverter plus brake chopper, and the CLA can execute a sensorless field-oriented-control loop at 10–20 kHz. Typical end products include servo drive control modules, AC drive control modules, and linear motor power stages.

Digital Power Conversion. Solar inverters and AC-input BLDC motor drivers benefit from the combination of the FPU, high-resolution PWM, and fast ADC, which together enable tight regulation of output voltage and current.

Appliance and Automotive Control. Air conditioner outdoor units and elevator door drive controllers represent volume applications where the single 3.3 V supply and integrated power-on reset simplify system design.

Sensing and Signal Processing. The combination of the VCU for complex math and CRC, along with the high-throughput ADC, supports applications in electrical vehicle sensing and advanced signal processing.

The TMS320F28062PZT is a purpose-built microcontroller that prioritizes control determinism, analog integration, and arithmetic efficiency over raw general-purpose throughput. Its FPU, CLA, and VCU form a three-tier compute architecture that maps naturally onto the layered structure of modern motor control and digital power algorithms. For engineers designing systems where a few hundred nanoseconds of loop latency can mean the difference between stable and marginal operation, the F28062PZT offers a well-balanced platform.
