The MSP430F122IPWR: The 4 KB Flash (4 K × 8 plus 256 B information memory) and 256 × 8 RAM are the tightest memory tiers in the MSP430x1xx family.
The 28-TSSOP package (4.40 mm width) is a surface-mount footprint suited for automated assembly on standard PCB processes. The 22 I/O lines are multiplexed with the on-chip peripherals; verify pin allocation for SPI and UART against your sensor interface before layout freeze.
The MSP430F122IPWR is rated for an 8 MHz CPU clock speed, which sets the ceiling for instruction throughput and peripheral baud rates.
The MSP430F122IPWR belongs to the MSP430x1xx series, a low-power 16-bit MCU family from Texas Instruments.
