General-purpose microcontroller "MSPM0 series"

Texas Instruments' (TI) MSPM0 series microcontrollers feature a low-power Arm® Cortex®-M0+ core and a wide range of analog and communication peripherals, achieving high performance at a low price point.

The MSPM0 series is a microcontroller designed for a wide range of embedded applications, including home appliances, industrial equipment, building equipment, measuring instruments, and medical devices.
Equipped with a wealth of analog functions and various communication interfaces, it is also suitable for systems requiring motor control, power supply control, and CAN/LIN communication.

Features

TImanufactures 300mm wafers using its own 65nm process at its own factory, ensuring a stable supply.
Excellent expandability thanks to a wide range of analog peripherals.
Ultra-low power consumption, operating at 1.0 μA in standby mode.
The DSBGApackage (8-pin) achieves an extremely small size of 1.6mm x 0.85mm.
Accelerate development with the provision of a wealth of software (driver libraries) and SysConfig (GUI tool).

portfolio

The MSPM0 series offers the following lineup, categorized by package and flash memory type:
The Arm® Cortex®-M0+ core is divided into series based on its operating frequency: the C series is 24MHz, the L series is 32MHz, and the G series is 80MHz.
Basically, all products operate on a 3.3V power supply (some pins are rated for 5V). However, only the MSPM0H series can be operated at 5V.

MSPM0C series

The C series offers packages as small as 1.6mm x 0.85mm, and is a series designed with miniaturization in mind.
It features an ADC, DAC, timer (PWM), and RTC, and supports serial communication via UART, SPI, and I2C.
