3 Description

MSPM0Lx22x microcontrollers (MCUs) are part of the highly integrated, ultra-low-power 32-bit MSPM0 MCU

family based on the Arm® Cortex®-M0+ 32-bit core platform, operating at up to 32MHz frequency. These

MCUs offer a blend of cost optimization and design flexibility for applications requiring 128KB to 256KB of

flash memory in small packages (down to 4mm x 4mm) or high pin count packages (up to 80 pins). These

devices include a VBAT backup island, an optional segmented LCD controller (on MSPM0L222x), cybersecurity

enablers, and high-performance integrated analog, and provide excellent low-power performance across the

operating temperature range.

Up to 256KB of embedded flash program memory with built-in error correction code (ECC) and up to 32KB

SRAM with ECC and parity protection is provided. The flash memory is organized into two main banks to support

field firmware updates, with address swap support provided between the two main banks. An additional 32-byte

backup memory is provided in the VBAT island, supplied by the VBAT pin and retained even when the main

supply (VDD) is lost.

The VBAT island provides a fully independent auxiliary power domain (separate from the main supply) which

supplies low frequency modules from an alternate supply such as a battery, supercapacitor, or alternate voltage

level (1.62V to 3.6V). The VBAT island includes the low-frequency clock system (LFOSC, LFXT), the real-time

clock, the tamper detection, and timestamp logic, an independent watchdog timer, and a 32-byte backup

memory. Up to five digital IOs are powered from the VBAT supply. A charging mode is provided to optionally

trickle charge a supercapacitor on the VBAT pin from the primary (VDD) supply when VDD is greater than VBAT.

An ultra-low power segmented LCD controller (on MSPM0L2228 and MSPM0L2227 devices) supports driving

LCD glass with up to 59 pins in a variety of mux and bias configurations, enabling low cost displays.

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 Arm® PSA

Level 1 certified.

A set of high-performance analog modules is provided, including a 12-bit 1.68Msps SAR ADC supporting up

to 26 external channels. An analog comparator is provided to support low power or low latency monitoring of

analog signals. An on-chip voltage reference (1.4V or 2.5V) can be used to provide a stable reference voltage

to the ADC and comparator. Environmental monitoring of the die temperature using the internal temperature

sensor, VDD voltage, and VBAT voltage is supported.

The TI MSPM0 family of low-power MCUs consists of devices with varying degrees of analog and digital

integration allowing for customers find the MCU that meets their project's needs. The MSPM0 MCU platform

combines the Arm Cortex-M0+ platform with a holistic ultra-low-power system architecture, allowing system

designers to increase performance while reducing energy consumption.

MSPM0Lx22x 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 available for

purchase. 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.
