That variant shares the same 14-TSSOP footprint, 16 MHz core, 2 KB Flash, and 128 x 8 RAM, but drops the AEC-Q100 automotive qualification. If your application does not require the Q1 grade, the non-Q1 part is a direct drop-in. ## 16 MHz, 2 KB Flash – sizing the firmware budget The 16 MHz CPU16 core is adequate for simple sensor polling, I²C/SPI communication, and PWM generation. The 2 KB Flash fills a tight firmware footprint – think a single control loop with a lookup table, not a multi-layer protocol stack. The 128 x 8 RAM (128 bytes) limits stack depth and variable storage; any significant buffering or floating-point math will overflow. ## Sourcing the MSP430G2231IPW4Q1 now Because this part is obsolete, the usual franchised channels will not carry it. Independent distributors hold whatever surplus remains – typically pulled from overstock or cancelled orders. If you need a large volume or a specific date code, expect to work with a broker who can trace the supply chain back to TI's original production.","metaTitle":"TI MSP430G2231IPW4Q1 16-bit MCU, 16 MHz, AEC-Q100, 14-TSSOP","metaDescription":"Texas Instruments MSP430G2231IPW4Q1 16-bit MCU, 16 MHz, 2 KB Flash, 128 B RAM, AEC-Q100 automotive grade, 14-TSSOP.","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":"Tube","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":"14-TSSOP (0.173\\\", 4.40mm Width)","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":"14-TSSOP","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/59f1fd9bfbfdd5212c2495d38c4af6e5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430G2231IPW4Q1/alternatives.json"},"ai":{"faq":[{"question":"Is MSP430G2231IPW4Q1 obsolete and what are my options?","answer":"Yes, it is obsolete.
