The 16 general-purpose I/O pins, plus I²C, SPI, and UART serial interfaces, cover basic peripheral integration without an external bridge chip. ## 256-byte RAM — planning the data buffer The 256 x 8 RAM is the tightest resource on this part. A UART receive buffer, a few sensor readings, and the call stack can fill it quickly. For designs that log data or handle multi-byte packets, the firmware needs to move samples to Flash promptly or use a circular buffer smaller than 128 bytes. The base product number MSP430G2303 covers the whole density variant family, so if a future design needs more memory, a pin-compatible upgrade within the same package is possible without a board spin. ## 20-TSSOP footprint and tape-and-reel delivery Store the reels dry: TSSOP packages are MSL-rated, and the reel should stay in the moisture-barrier bag until the reflow oven is ready.","metaTitle":"TI MSP430G2303IPW20R 16-bit MCU, 16MHz, 4KB Flash, 20-TSSOP","metaDescription":"Texas Instruments MSP430G2303IPW20R 16-bit MCU, 16MHz core, 4KB Flash, 256B RAM, I²C/SPI/UART, 1.8V-3.6V, -40°C~85°C, 20-TSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"16MHz","Series":"MSP430G2xx","Package":"Tape & Reel (TR)","RAM Size":"256 x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"16","Core Processor":"MSP430 CPU16","Package / Case":"20-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Active","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430G2303","Program Memory Size":"4KB (4K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"20-TSSOP","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8165","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/aa1021d14ccf54bbadb16cd01958dd1f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430G2303IPW20R/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between MSP430G2303IPW20R and MSP430G2303IPWR?","answer":"The difference is the package suffix: MSP430G2303IPW20R uses a 20-TSSOP package, while MSP430G2303IPWR uses a 28-TSSOP package.
