The 4 KB flash and 512 B RAM limit the firmware to a small control loop with a modest lookup table; expect to fit a PID loop, a Modbus RTU slave, or a battery-monitor state machine in that budget. ## 28-TSSOP — rework-friendly and board-fit The -40 to 105°C operating range covers industrial enclosures and outdoor telecom cabinets without active cooling. ## On-chip peripherals — what is built in Brown-out detect and POR reset the MCU cleanly on power-up and during supply dips — no external supervisor needed for most single-rail designs. The internal oscillator trims to ±1% accuracy over temperature, so a separate crystal is optional for UART baud-rate tolerance. The 8-channel 10-bit ADC samples at up to 200 ksps; the input mux accepts both analog and digital pins, so the same 24 I/O lines can serve as keypad inputs or temperature-sensor channels. Active and available through independent distribution.","metaTitle":"MSP430F2122TPW 16-bit MCU, 16 MHz, 4 KB Flash, 28-TSSOP","metaDescription":"Texas Instruments MSP430F2122TPW, 16 MHz MSP430 CPU16, 4 KB flash, 512 B RAM, 24 I/O, 8x10b ADC, -40 to 105°C, 28-TSSOP.
