MSPM0L1117SRGER

The MSPM0L111x microcontrollers (MCUs) are part of a highly integrated, ultra-low-power 32-bit MSP MCU family based on the enhanced Arm® Cortex®-M0+ core platform, operating at up to 32MHz. These cost-optimized MCUs offer high-performance analog peripheral integration with excellent low-power current characteristics. The MCUs support an extended temperature range of -40°C to 125°C and an operating supply voltage range of 1.62V to 3.6V. The devices feature up to 128KB of embedded Flash with built-in ECC and up to 16KB of SRAM. The Flash is organized into two main banks to support field firmware updates, with address swap support between the two main banks. A flexible cybersecurity enablement toolkit supports secure boot, secure field firmware updates, IP protection (execute-only memory), key storage, and more. Hardware acceleration is provided for multiple AES symmetric cipher modes, along with a TRNG entropy source. This cybersecurity architecture is pending Arm® PSA Level 1 certification. These MCUs integrate a high-speed on-chip oscillator with accuracy up to ±1.2%, eliminating the need for an external crystal. Additional features include a 3-channel DMA, a 16-bit/32-bit CRC accelerator, and a variety of high-performance analog peripherals, such as a 12-bit 1.68Msps ADC with a configurable internal voltage reference and an on-chip temperature sensor. The devices also provide intelligent digital peripherals, including one 16-bit advanced control timer, two 16-bit general-purpose timers, one general-purpose timer with quadrature encoder input, a windowed watchdog and an independent watchdog, as well as multiple communication peripherals including one I2C, one SPI, and two UARTs (one with LIN protocol support). The TI MSPM0 low-power MCU family includes devices with varying levels of analog and digital integration, helping customers find the right MCU for their project requirements. The architecture, combined with rich low-power modes, is optimized for long battery life in portable measurement applications. The MSPM0L111x MCUs are supported by a rich software and hardware ecosystem, with reference designs and code examples for rapid design starts. The development kit includes a purchasable LaunchPad™ development kit and design files for target socket boards. TI also provides a free MSP Software Development Kit (SDK), available in both the desktop and cloud versions of the Code Composer Studio™ IDE via TI Resource Explorer. MSPM0 MCUs are further supported by extensive online resources, MSP Academy training, and the TI E2E™ support forum.
