XMSM0L1117SPTR [Texas Instruments]

MSPM0L111x microcontrollers (MCUs) are part of the MSP highly-integrated, ultra-low-power 32-bit MCU family based on the enhanced Arm Cortex-M0+ core platform operating at up to 32MHz frequency. These cost-optimized MCUs offer high-performance analog peripheral integration and excellent low-power current consumption. The MCUs also support extended temperature ranges from -40°C to 125°C and operate with supply voltages ranging from 1.62V to 3.6V.

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 is organized into two main banks to support field firmware updates, with address swap support provided between the two main banks.

Flexible cybersecurity enablers can be used to support secure boot, secure in-field firmware updates, IP protection (execute-only memory), key storage, and more. Hardware acceleration is provided for a variety of AES symmetric cipher modes, as well as a TRNG entropy source. The cybersecurity architecture is pending Arm® PSA Level 1 certification.

These MCUs incorporate a high-speed on-chip oscillator with an accuracy up to ±1.2%, eliminating 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 configurable internal voltage reference and an on-chip temperature sensor. These devices also 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, windowed and independent watchdog timer, and a variety of communication peripherals including one I2C, one SPI, and two UARTs (one with support for LIN protocol).

The TI MSPM0 family of low-power MCUs consists of devices with varying degrees of analog and digital integration allowing for customers to find the MCU that meets their project’s needs. The architecture combined with extensive low-power modes are optimized to achieve extended battery life in portable measurement applications.

MSPM0L111x MCUs are supported by an extensive hardware and software ecosystem with reference designs and code examples to get the design started quickly. Development kits include a LaunchPad™ development kit available for purchase and design files for a target-socket board. TI also provides a free MSP Software Development Kit (SDK), which is available as a component of Code Composer Studio™ IDE desktop and cloud version within the TI Resource Explorer. MSPM0 MCUs are also supported by extensive online collateral, training with MSP Academy, and online support through the TI E2E™ support forums.
