Texas Instruments MSPM0Lx22x/MSPM0Lx22x-Q1 Mixed-Signal MCUs

Texas Instruments MSPM0Lx22x/MSPM0Lx22x-Q1 Mixed-Signal 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.

These Texas Instruments MSPM0Lx22x/MSPM0Lx22x-Q1 Mixed-Signal MCUs provide up to 256KB of embedded Flash program memory with built-in error correction code (ECC) and up to 32KB of SRAM with ECC and parity protection. 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) that 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. The VBAT supply powers up to five digital IOs. 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/MSPM0L2228-Q1 and MSPM0L2227/MSPM0L2227-Q1 devices) supports driving LCD glass with up to 59 pins in various mux and bias configurations, enabling low-cost displays.

Flexible cybersecurity enablers can 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 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 MSPM0Lx22x-Q1 devices are AEC-Q100 qualified for automotive applications.
