It packs 4 KB of Flash program memory (4K x 8 plus 256 B) and 512 x 8 of RAM, with 24 general-purpose I/O lines.
Peripheral set and integration
On-chip peripherals include a brown-out detect/reset, power-on reset, PWM timer, and watchdog timer — enough to handle basic motor drive timing and system supervision without external glue. The serial interface bundle covers I²C, IrDA, LINbus, SCI, SPI, and UART/USART, so it can talk to most common sensors, displays, and wireless modules. The 8-channel 10-bit ADC handles analog inputs like temperature or battery voltage monitoring.
The MSP430F2xx series is a mature, widely deployed family, and TI continues to manufacture it.
