MSP430F2234IDAR

MSP430F2234IDAR is a TI MSP430 16-bit ultra-low-power microcontroller (MSP430x2xx family). It combines a 16-bit RISC CPU with on-chip flash and RAM, typically running up to 16 MHz. Peripherals include timers, a 10-bit ADC, and serial I/O (UART/SPI/I2C via USCI), plus a watchdog timer and multiple low-power modes. Operation is in the 1.8–3.6 V range, emphasizing very low sleep current for battery-powered apps. The IDAR suffix denotes a specific package/temperature grade per TI naming; consult the datasheet for exact pinout and memory size. Typical uses: sensors, portable instruments, and small embedded controllers. Development via Code Composer Studio or IAR with MSP430Ware.
