The Texas Instruments MSP430FR2522IPW16R is a 16-bit MSP430 CPU16 microcontroller clocked at 16 MHz, built around the MSP430™ FRAM series. It carries 7.5 KB of FRAM program memory and 2 KB of RAM, with 11 GPIO lines, a 5-channel 10-bit ADC, and serial connectivity covering I²C, SPI, and UART. The part operates from 2 V to 3.6 V supply over the -40°C to 85°C industrial temperature range, housed in a 16-TSSOP package.
That means the 7.5 KB program space can be updated in-field without a separate EEPROM for calibration constants or data logs — the same memory handles code and nonvolatile storage. Write endurance is effectively unlimited for typical embedded update rates, so wear-leveling routines are unnecessary.
At 16 MHz, the MSP430 CPU16 executes most single-cycle instructions. The 5-channel 10-bit ADC samples at rates suitable for thermistor, potentiometer, or low-speed analog front-ends.
IrDA and SCI extend the UART for infrared and LIN-class communication.
