On-chip peripherals include a 10-bit ADC with 8 multiplexed channels, brown-out detect, POR, DMA, PWM, and a watchdog timer — enough to handle sensor fusion, simple motor control, or keypad scanning without external glue logic.
All 16 I/O are brought out on this 20-pin footprint.
Within the same 20-pin TSSOP footprint, the MSP430G2553IPW20 offers a step up to 16 KB Flash and 512 B RAM while remaining pin-compatible. The MSP430G2453IPW20 is the 8 KB Flash variant, so the firmware image must fit within that smaller memory ceiling.
The core processor runs at 16 MHz, which is the maximum clock frequency supported by the internal oscillator without external timing components.
