Automotive 160MHz Arm® Cortex®-M33 MCU with TrustZone®, 1MB flash, 256kB SRAM, QSPI and security

MSPM33C32xx 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.

MSPM33C32xx 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.

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 optionally SPI. Flexibility in configuration and pinout gives

system designers a simple path to support challenging requirements.

MSPM33C32xx 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.

MSPM33C32xx 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. MSPM33C32xx 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.
