3 Description

MSPM0C1105/6 microcontrollers (MCUs) are part of MSP's 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 cost-optimized MCUs offer high-performance analog peripheral integration, support extended temperature

ranges from -40°C to 125°C, and operate with supply voltages from 1.62V to 3.6V.

The MSPM0C1105/6 devices provide up to 64KB embedded flash program memory with 8KB SRAM. These

MCUs incorporate a high-speed on-chip oscillator with an accuracy from -2.1% to +1.6%, eliminating the need

for an external crystal. Additional features include a 3-channel DMA, CRC-16 accelerator, and a variety of

high-performance analog peripherals such as one 12-bit 1.6 Msps ADC with VDD as the voltage reference, a

comparator with 8-bit reference DAC and an on-chip temperature sensor. These devices also offer intelligent

digital peripherals such as one 16-bit advanced timer with deadband and timer frequency up to 64MHz, four 16-

bit general purpose timer, one windowed watchdog timer, and a variety of communication peripherals including

three UART, one SPI, and two I2C. These communication peripherals offer protocol support for LIN, IrDA, DALI,

Manchester, smart card, SMBus, and PMBus.

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

integration allowing for customers to find the MCU that meets the 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.

MSPM0C1105/6 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.
