Texas Instruments MSPM0G350x Mixed-Signal MCUs with CAN-FD

Texas Instruments MSPM0G350x Mixed-Signal MCUs with CAN-FD Interface are part of the MSP highly integrated, ultra-low-power 32-bit MCU family. These MSPM0G350x are based on the enhanced Arm^® Cortex^®-M0+ 32-bit core platform operating at up to 80MHz frequency. The MSPM0G350x MCUs offer up to 128KB embedded flash program memory with built-in Error Correction Code (ECC) and up to 32KB SRAM with hardware parity option. These MCUs provide intelligent digital peripherals such as five general-purpose timers, 16-bit advanced control timers, two windowed-watchdog timers, and one RTC with alarm and calendar modes.

The TI MSPM0G350x MCUs provide data integrity and encryption peripherals (AES, CRC, and TRNG) and improved communication interfaces (four UART, two I2C, two SPI, and CAN 2.0/FD). These MCUs support an extended temperature range of -40°C to 125°C and operate with supply voltages ranging from 1.62V to 3.6V.
