Texas Instruments MSPM0L111x Mixed-Signal Microcontrollers (MCUs)

The device has up to 128KB of embedded flash memory with built-in error correction code (ECC) and up to 16KB SRAM. The flash memory supports field firmware updates and is being organized into two main banks, with address swap support provided between the two main banks. Flexible cybersecurity enablers can support secure boot, IP protection (execute-only memory), secure in-field firmware updates, key storage, and more. Hardware acceleration is provided for a TRNG entropy source and various AES symmetric cipher modes. The cybersecurity architecture is pending Arm PSA Level 1 certification.

The Texas Instruments MSPM0L111x MCUs incorporate a high-speed on-chip oscillator with an accuracy of up to ±1.2%. This feature eliminates the need for an external crystal. Additional features include a 3-channel DMA, 16-bit/32-bit CRC accelerator, and a variety of high-performance analog peripherals such as one 12-bit 1.68Msps ADC with an on-chip temperature sensor and configurable internal voltage reference. These MCUs offer intelligent digital peripherals such as one 16-bit advanced control timer and two 16-bit general purpose timers, one general purpose timer with Quadrature Enabled Input, an independent and windowed watchdog timer, and a variety of communication peripherals including one I²C, one SPI, and two UARTs (one with support for LIN protocol).
