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.
318:: 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. 117:
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.
612: 294:: 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. 495:
Similar to the P401R launchpad, this supports a larger chip with 2 MB flash, 256 KB SRAM and also has a 320-segment LCD display leveraging the chip's LCD_F peripheral.
