Ten general-purpose I/O lines are available in the 16-QFN package (4x4 mm), with the exposed pad aiding thermal dissipation in compact designs. Built-in peripherals include brown-out detection (BOR), power-on reset (POR), a PWM timer, and a watchdog timer (WDT) — covering the basics for reliable standalone operation without external supervisor ICs. ## Industrial temperature range and compliance ROHS3 compliant per the manufacturer's declaration, with no halogenated flame retardants in the package.","metaTitle":"Texas Instruments MSP430G2131IRSA16R MCU, 16 MHz, 1 KB Flash","metaDescription":"Texas Instruments MSP430G2131IRSA16R 16-bit MCU, 16 MHz, 1 KB Flash, 128 B RAM, 10 GPIO, 8ch 10-bit ADC, I²C/SPI, -40°C to 85°C, 16-QFN.","metaKeywords":null},"attributes":{"series":"MSP430G2xx","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"16MHz","Series":"MSP430G2xx","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"128 x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, SPI","Mounting Type":"Surface Mount","Number of I/O":"10","Core Processor":"MSP430 CPU16","Package / Case":"16-VQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430G2131","Program Memory Size":"1KB (1K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"16-QFN (4x4)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7800","priceTiers":[{"qty":1,"price":"$1.78000","currency":"USD"},{"qty":10,"price":"$1.60300","currency":"USD"},{"qty":25,"price":"$1.51200","currency":"USD"},{"qty":100,"price":"$1.28820","currency":"USD"},{"qty":250,"price":"$1.20960","currency":"USD"},{"qty":500,"price":"$1.05840","currency":"USD"},{"qty":1000,"price":"$0.87696","currency":"USD"},{"qty":3000,"price":"$0.81648","currency":"USD"},{"qty":6000,"price":"$0.78624","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/dcffd4e87ef2e9a7c45ca4c675b25e04.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430G2131IRSA16R/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional second-source for MSP430G2131IRSA16R — F280041PZQR?","answer":"The F280041PZQR is a different architecture (C2000 C28x 32-bit core at 100 MHz) with more memory, more I/O, and automotive qualification.
