16-bit MCU for battery and sensor-edge designs
It runs the MSP430 CPU16 core at 16 MHz and packs 16 KB of Flash program memory with 512 bytes of RAM — enough for sensor fusion, simple control loops, and serial protocol handling in a single-chip BOM. The part integrates a 10-bit ADC with eight channels, an internal oscillator (no external crystal needed for most applications), and serial connectivity spanning I²C, SPI, UART, IrDA, and LINbus. Twenty-four general-purpose I/O lines provide ample headroom for keypad scanning, LED driving, or discrete sensor inputs.
Memory and peripheral budget for the BOM line
16 KB of Flash means the firmware image must be lean — typical for a single-function control task (e.g., a thermostat or occupancy sensor). The 512-byte RAM limits data buffering to a few hundred bytes; if your application needs a large frame buffer or multi-packet serial queue, step up to the 1 KB RAM variants in the MSP430G2xx family. The on-chip 10-bit ADC with eight channels covers most analog sensor interfaces without an external converter.
