MSPM33C32xx micontrollers (MCUs) are part of the MSP general purpose 32-bit MCU family operating at up to 160MHz based on the Arm Cortex-M33 32-bit core with Arm TrustZone technology, DSP, and FPU. This family of MCUs features flexible communication interfaces, high-performance analog, and security accelerators. The extended temperature range and wide supply voltage range make this family of MCUs suitable for a variaety industrial, enterprise and personal electronics applications.
MSPM33C32xx MCUs provide up to 1MB of embbeded flash program memory and 256kB SRAM. An additional high-endurance 32kB flash data bank is provided for application data storage. All memories feature built-in error correction code (ECC) across the entire memory range to ensure robust operation across their entire lifetime.
MSPM33C32xx MCUs offer many different types of digital communication interfaces including CAN, I2S/TDM, Quad SPI (QSPI), UART, I2C, and SPI. Configurable serial interfaces can be dynamically assigned in software as UART, I2C and optionaly SPI. Flexilbity in configuraiton and pinout gives system designers a simple path to support challenging requirments.
MSPM33C32xx MCUs also feature high performance integrated analog peripherals such as two 12bit 9.4 MSPS simultaneous sampling ADC and two high-speed comparators. Comparators can be used internally for fault detection with advanced timers or externally as low-power voltage monitors.
MSPM33C32xx MCUs contain a robust collection of security features. TrustZone technology and the Global Security Controller provide a complete feature set to build secure applications. These devices also feature an immutable root of trust (RoT) which provides secure boot, install and key provisioning out of the box. MSPM33C32xx also includes hardware acceleration for AES, SHA and Public Key algorithms (RSA and ECC).
MSPM33C series of devices is pin-to-pin compatible with other MSPM33C devices in the same package. MSPM33C series is also highly pin-to-pin compatible with MSPM0 devices. In scenerios where there are differences between MSPM33C and MSPM0 devices users can use TI System Configurator or provided documentation to understand how to navigate minor incompatibilities.
MSPM33C family of 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. MSPM33C MCUs are also supported by extensive online collateral, training with MSP Academy, and online support through the TI E2E™ support forums.
