FRAM micro, 16 MHz — what you actually get
FRAM replaces both Flash and EEPROM — no wear-leveling code needed, writes happen at full speed, and standby current drops because FRAM doesn't need a write pump.
11 I/O with 5-channel 10-bit ADC — connectivity on a slim footprint
Eleven general-purpose I/O lines paired with a 5-channel 10-bit ADC give this MCU enough analog front-end for sensor interfaces, knob inputs, or battery monitoring. The connectivity block—I²C, SPI, UART, plus IrDA and SCI—covers serial bus work for small control panels or low-speed data links. Surface-mount 16-TSSOP keeps board area tight; no external oscillator needed, the internal clock runs the core at 16 MHz.
TI lists the MSP430FR2422IPW16 as Active. No last-time-buy window is open, no successor has been announced. New designs can proceed without worrying about a forced migration mid-production.
