Comparison to MSP430/MSP430X

Modern embedded computing requires large amounts of data and code, and often calls for floating point calculations. The MSP430's 16-bit architecture was already once extended to 20 bits (MSP430X) to accommodate those needs, but the resulting 1 MB limit is still too small, and the instruction set extensions slow down the code execution. Furthermore, MSP430 architecture does not include a hardware floating point unit.

floating point computations are emulated in software using integer arithmetic on its native 16-bit data, and are quite slow. The ARM Cortex-M4F architecture used in the MSP432 line allows up to 4 GB of unified program/data/peripheral memory, and has a built-in single precision

-compatible Floating Point Unit.
The peripherals in MSP432 are similar to those in MSP430, and there is a built-in ROM driver library that facilitates software reuse. Differences from MSP430 include: * redesigned interrupt mechanism, using Nested Vectored Interrupt Controller (NVIC) * improved resolution (14-bit) and speed (1 MSPS) ADC * redesigned uDMA engine * ARM-specific SysTick and Timer32 timer/counter blocks


Relationship to other TI ARM Cortex-M devices

The MSP432 is similar to the Stellaris LM4F120 and Tiva-C TM4C123 parts previously available from TI. The MSP432 is slightly slower, cheaper and uses significantly less power, and tends to have less of the sophisticated peripherals such as wide 32/64-bit timer units, or the quadrature encoder blocks. In fall of 2017 TI expanded the family with higher performance parts containing Ethernet, USB, CAN and SPI peripherals. In 2017 the Tiva TM4C129 was rebranded as the MSP432 "E-series" SimpleLink MSP432E4 Ethernet microcontrollers"">"SimpleLink Wired MCUs > SimpleLink MSP432E4 Ethernet microcontrollers"
/ref> but with added features including: AES Module, SHA/MD5 Module, DES Module. Several new subsystems were introduced in MSP432: * Port Mapping Controller (PMAP) maps built-in peripherals to physical pins * Power Control Manager (PCM) switches between full speed and low power modes (LPM 0, 3, 3.5, 4 and 4.5). * AES and CRC hardware accelerator


MSP432 devices

The MSP432 devices are named similarly to those of the MSP430. For instance MSP432P401RIPZT consists of the following pieces: * MSP432: Standard prefix. * P: Indicates a Performance and Low Power series device. 'E' denotes parts with built-in communication interfaces such as Ethernet, USB, CAN and SPI; those parts have a significantly higher power envelope. * 4: First digit '4' indicates a flash 48 MHz device. * 0: Second digit '0' indicates a General Purpose class, '1' has expanded peripherals such as an LCD controller. * 1: Third digit '1' denotes peripheral configuration including 1 MHz 14-bit ADC. * R: Fourth digit 'R' indicates 256 KB of Flash and 64 KB of SRAM, whereas 'M' indicates 128 KB of Flash and 32 KB of SRAM, 'V' means 512 KB Flash and 128 KB SRAM, 'Y' means 1024 KB Flash and 256 KB SRAM, and '1' denotes 2048 KB Flash and 256 KB SRAM. * T: following the 4xxx model designator seems to denote lower clock version (typically 24 MHz) that has lower overall power consumption but higher leakage * I: Temperature range: S = 0...50 °C, I = -40...85 °C, T = –40..105 °C. * PZ: Packaging code * T: Distribution format: small reel
