No last-time-buy window or successor part number is recorded in the official lifecycle data. ## 16 MHz core — enough for sensor-level control loops The 16 MHz clock rate, driven by an internal oscillator, is typical for the MSP430G2 value line. It handles basic sensor polling, PWM generation, and serial communication without external timing components. The 128-byte RAM limits buffer depth — expect to run tight interrupt service routines and avoid large lookup tables in RAM. The 2 KB Flash is sufficient for small state machines and calibration tables, but leaves no room for a real-time operating system or over-the-air update staging. ## 16-QFN with exposed pad — layout and rework notes The pad also serves as the primary electrical ground connection — a poor solder joint here can cause intermittent brown-out resets.","metaTitle":"TI MSP430G2231IRSAQ1 16-bit MCU, 16 MHz, 2 KB Flash","metaDescription":"Texas Instruments MSP430G2231IRSAQ1 16-bit MCU, 16 MHz, 2 KB Flash, 128 B RAM, AEC-Q100 automotive grade.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"16MHz","Series":"Automotive, AEC-Q100, MSP430G2","Package":"Tray","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":"Obsolete","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430G2231","Program Memory Size":"2KB (2K 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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fa8d4e371cab55492ccab559153f4d10.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430G2231IRSAQ1/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430G2231IRSAQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430G2231IRSAQ1 when reusing this data.
