MSPM0G1518SPM

The MSPM0Gx51x MCUs belong to the MSP high-integration, ultra-low-power 32-bit MCU family, based on an enhanced Arm® Cortex®-M0+ 32-bit core platform with a maximum operating frequency of 80MHz. These MCUs balance cost optimization and design flexibility for applications requiring 256KB to 512KB of flash memory in small or high pin-count packages (up to 100 pins). These devices integrate dual CAN-FD controllers, cybersecurity features, and high-performance integrated analog peripherals, delivering excellent low-power performance across the full operating temperature range. The devices feature up to 512KB embedded flash program memory with built-in error correction code (ECC), and up to 128KB SRAM (the first 64KB with ECC and parity protection). The flash is organized into two main memory banks supporting field firmware updates, with address swap support between the two main banks. Flexible cybersecurity features support secure boot, secure field firmware updates, IP protection (execute-only memory), key storage, and more. Hardware acceleration supports multiple AES symmetric cipher modes, and a true random number generator (TRNG) entropy source is also provided. The security architecture targets Arm® PSA Level 1 certification. A set of high-performance analog modules is provided, including two 12-bit 4Msps ADCs capable of simultaneous sampling with support for up to 27 external channels; an on-chip voltage reference (1.4V or 2.5V); a 12-bit 1Msps DAC; and three comparators operable in low-power and high-speed modes, each with an additional built-in 8-bit reference DAC. The TI MSPM0 low-power MCU family includes devices with varying levels of analog and digital integration, helping customers find the MCU that best meets their project requirements.
