The 16-bit core works efficiently on byte and word operations, but the RAM ceiling means no large buffers or RTOS with multiple stacks. ## USI serial engine — I²C and SPI with firmware assist The Universal Serial Interface (USI) handles I²C and SPI, but it is a software-assisted module — the core manages bit-level timing and state transitions. At 16 MHz the SPI bit rate is adequate for short-frame sensor reads (a few hundred kHz), but do not expect hardware FIFO throughput. The USI shares pins with other I/O, so the 16 available I/O lines shrink when both serial interfaces are active. ## 20-TSSOP footprint and layout notes Decouple Vcc with a 100 nF ceramic close to pin 20 and a 4.7 µF bulk cap somewhere on the board. The internal oscillator runs at 16 MHz without an external crystal, saving two pins and a layout trace — useful when board area is tight.","metaTitle":"Texas Instruments MSP430G2402IPW20 16-bit MCU, 16 MHz","metaDescription":"Texas Instruments MSP430G2402IPW20 16-bit MCU, MSP430 CPU16 core at 16 MHz, 8 KB Flash, 256 x 8 RAM, I²C/SPI, 20-TSSOP, -40°C to 85°C.
