Description

The TI CC430 family of ultra-low-power system-on-chip (SoC) microcontrollers with integrated RF transceiver cores consists of several devices that feature different sets of peripherals targeted for a wide range of applications. The architecture, combined with five low-power modes, is optimized to achieve extended battery life in portable measurement applications. The devices feature the powerful MSP430 16‑bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency.

The CC430 family provides a tight integration between the microcontroller core, its peripherals, software, and the RF transceiver, making these true SoC solutions easy to use as well as improving performance.

The CC430F61xx series are microcontroller SoC configurations that combine the excellent performance of the state-of-the-art CC1101 sub-1 GHz RF transceiver with the MSP430 CPUXV2, up to 32KB of in-system programmable flash memory, up to 4KB of RAM, two 16-bit timers, a high-performance 12-bit ADC with eight external inputs plus internal temperature and battery sensors on CC430F613x devices, a comparator, USCIs, a 128-bit AES security accelerator, a hardware multiplier, a DMA, an RTC module with alarm capabilities, an LCD driver, and up to 44 I/O pins.

The CC430F513x series are microcontroller SoC configurations that combine the excellent performance of the state-of-the-art CC1101 sub-1 GHz RF transceiver with the MSP430 CPUXV2, up to 32KB of in-system programmable flash memory, up to 4KB of RAM, two 16-bit timers, a high-performance 12-bit ADC with six external inputs plus internal temperature and battery sensors, a comparator, USCIs, a 128-bit AES security accelerator, a hardware multiplier, a DMA, an RTC module with alarm capabilities, and up to 30 I/O pins.
