1.2 MSPM0C110x Introduction

MSPM0C110x 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 24MHz frequency. These MCUs offer high-performance analog peripheral integration.

The MSPM0C110x devices provide up to 16KB embedded flash program memory with 1KB SRAM. This device integrates a variety of high-performance analog peripherals such as one 12-bit 1.5Msps ADC with VDD as the voltage reference, and an on-chip temperature sensor. The device also offers intelligent digital peripherals such as one 16-bit advanced timer, two 16-bit general purpose timer, one windowed watchdog timer, and a variety of communication peripherals including one UART, one SPI, and one I2C. These communication peripherals offer protocol support for LIN, IrDA, DALI, Manchester, smart card, SMBus, and PMBus
