16 MHz MSP430 core with 1 KB flash — what fits in the firmware budget
The MSP430F2002TPWR is a 16-bit microcontroller from the MSP430F2xx family, built around the MSP430 CPU16 core clocked at 16 MHz. The 1 KB on-chip flash (1K x 8 plus 256B) and 128 x 8 bytes of RAM set a tight firmware and data budget — suitable for single-purpose control loops, sensor readout, or simple communication bridges where the entire application fits in under a kilobyte of code. The 8-channel 10-bit ADC covers basic analog sensing — temperature, battery voltage, or current shunt — without an external converter. The I²C and SPI connectivity allows expansion to external sensors, EEPROM, or display modules when the on-chip resources are insufficient.
Industrial temperature grade and supply range — where it lives on the board
The 10 general-purpose I/O pins are shared with the ADC and serial peripheral functions — pin assignment must be planned at schematic capture to avoid conflicts.
