The Flash program memory is 8 KB — that is tight: the ADC driver, calibration constants, and a basic Modbus or UART framing will fit, but a full RTOS or USB stack will not. The 512 x 8 RAM (512 bytes) is similarly lean; expect to use register-based variables and a small stack. Brown-out detect and a watchdog timer are on-chip. The MSP430AFE231IPW comes in a 24-pin TSSOP package (4.40 mm width, 0.65 mm pitch), surface-mount only. With 11 general-purpose I/O lines, the pin count is limited — plan on sharing the SPI/UART peripheral for both configuration and data output.","metaTitle":"TI MSP430AFE231IPW 16-bit MCU, 12 MHz, 24-bit ADC","metaDescription":"Texas Instruments MSP430AFE231IPW 16-bit MCU with 12 MHz core, 8 KB Flash, 512 B RAM, integrated 24-bit sigma-delta ADC.
