A single UART receive buffer, a modest interrupt stack, and a few global variables can consume half of it. If your application uses the 10-bit ADC with DMA or queues serial data, budget the RAM before writing firmware — the MSP430G2553IPW20 has no external memory bus. The 16 KB Flash is generous for a 16-bit MCU at this price point, but the RAM ceiling is the real constraint for data-logging or multi-protocol stacks. ## I²C, SPI, UART — the serial toolbox For battery monitors, temperature sensors, and low-speed serial displays, the on-chip USCI modules handle the job without external transceivers for most short-reach links. The internal oscillator holds frequency across this range, but if your timing budget is tight, plan to calibrate it against a known reference during production test. The 20-TSSOP package is a standard footprint with broad second-source availability in the MSP430 ecosystem — though no direct pin-compatible alternate is listed on this record, the MSP430G2xx family shares the same core and peripheral set across density options, so a firmware port to a larger Flash or RAM variant stays within the same toolchain.","metaTitle":"MSP430G2553IPW20 16-bit MCU, 16 MHz, 16 KB Flash, 20-TSSOP","metaDescription":"Texas Instruments MSP430G2553IPW20 16-bit MCU with 16 MHz core, 16 KB Flash, 512 B RAM, I²C/SPI/UART, -40 to 85°C.
