Description for the MSPM33C321A
MSPM33C321x microcontrollers (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 variety of industrial, enterprise, and personal electronics applications.
MSPM33C321x MCUs provide up to 1MB of embedded 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.
MSPM33C321x 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 optionally SPI. Flexibility in configuration and pinout gives system designers a simple path to support challenging requirements.
MSPM33C321x MCUs also feature high performance integrated analog peripherals such as two 12-bit 9.4Msps simultaneous sampling ADC and two high-speed low-power comparators. Comparators can be used internally for fault detection with advanced timers or externally as low-power voltage monitors.
MSPM33C321x MCUs contain a robust collection of security features. TrustZone technology and the Global Security Controller (GSC) 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. MSPM33C321x also includes hardware acceleration for AES, SHA and Public Key algorithms (RSA and ECC). These devices provide an efficient Post Quantum Cryptography (PQC) software library support.
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 scenarios where there are differences between MSPM33C and MSPM0 devices users can use TI System Configurator or the migration guide 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.
