A typical application — reading a temperature sensor over I²C, logging a threshold crossing, and driving a PWM fan output — leaves about 600 bytes of Flash headroom after the MSP430 driver library and a minimal scheduler. The 128-byte RAM holds about 32 32-bit variables; any data logging or buffering beyond that needs external serial EEPROM or careful reuse of the register file. The internal oscillator trims to ±1% accuracy at 25°C, which is adequate for UART bit timing at 9600 baud without an external crystal. ## Supply voltage and power budgeting At 16 MHz active mode draws roughly 300 µA/MHz typical, so a 3.3 V rail feeding a 16 MHz loop pulls about 5 mA. The brown-out detect/reset (BOR) peripheral is included on-chip, eliminating an external supervisor IC in cost-sensitive designs. The 4 I/O pins are 5 V tolerant when configured as inputs, which simplifies level-shifting to legacy 5 V logic.","metaTitle":"TI MSP430G2230QDREP 16-Bit MCU, 16MHz, 2KB Flash","metaDescription":"Texas Instruments MSP430G2230QDREP 16-bit MCU, 16MHz, 2KB Flash, 128B RAM, 8-SOIC.
