The 16 MHz core speed gives you enough headroom for 10 µs interrupt service routines if you keep the code lean. ## On-chip peripherals that save board space The MSP430G2231 integrates a brown-out detect and power-on reset, a PWM timer, a watchdog timer, I²C and SPI serial interfaces, and the 10-bit ADC — all on a single die in a 14-pin TSSOP package. For a simple sensor hub or a brushed-DC motor controller with current-sense feedback, this peripheral set eliminates the need for external glue logic or a separate ADC. The 10 general-purpose I/O pins handle a few pushbuttons, LEDs, and a serial debug header.","metaTitle":"Texas Instruments MSP430G2231IPW14R 16-Bit MCU, 2KB Flash","metaDescription":"Texas Instruments MSP430G2231IPW14R 16-bit MCU with 16MHz core, 2KB Flash, 128B RAM, 8x10b ADC, I²C/SPI.
