描述 Description

MSPM0Gx51x microcontrollers (MCUs) are part of the MSP highly integrated, ultra-low-power 32-bit MCU family based on the enhanced Arm Cortex-M0+ 32-bit core platform, operating at up to 80MHz frequency. These MCUs offer a blend of cost optimization and design flexibility for applications requiring 256KB to 512KB of flash memory in small packages (down to 5mm x 5mm) or high pin count packages (up to 100 pins). These devices include dual CAN-FD controllers, cybersecurity enablers, high performance integrated analog, and provide excellent low power performance across the operating temperature range.

Up to 512KB of embedded flash program memory with built-in error correction code (ECC) and up to 128KB SRAM (with ECC and parity protection for the first 64kB). The flash memory is organized into two main banks to support field firmware updates, with address swap support provided between the two main banks.

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 pending Arm? PSA Level 1 certification.

A set of high performance analog modules is provided, such as two simultaneously sampling 12-bit 4Msps ADCs supporting up to 27 external channels, on-chip voltage reference (1.4V or 2.5V), one 12-bit 1Msps DAC, and three high speed comparators with built-in 8-bit reference DACs operable in low-power and high-speed modes.

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.

MSPM0Gx51x 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 MSPM0 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.
