If you need a pin-compatible alternative in the same 14-TSSOP footprint, the MSP430G2231IPW4Q1 (also AEC-Q100, 2 KB Flash, same peripherals) is a direct drop-in; verify the firmware fits the larger memory. The 16 MHz core speed is adequate for bit-banged I²C/SPI at 400 kHz and PWM frequencies up to a few tens of kHz — enough for a brushed DC motor pre-driver or a cabin-light dimmer. The 1 KB Flash is the tight constraint: compiled C with the MSP430 GCC toolchain leaves room for maybe 500–700 instructions plus a modest lookup table. The 128-byte RAM handles a few sensor samples and stack frames, but any buffering beyond a single ADC conversion requires external serial EEPROM. The 8-channel 10-bit ADC resolves 5 mV steps on a 3.3 V reference — fine for a thermistor or potentiometer, marginal for a precision pressure sensor. The 10 I/O lines in the 14-TSSOP package leave enough for a few switches, an LED, and a serial bus after the ADC inputs are assigned.","metaTitle":"MSP430G2131IPW4Q1 16-bit MCU, 16 MHz, 1 KB Flash, AEC-Q100","metaDescription":"Texas Instruments MSP430G2131IPW4Q1 automotive 16-bit MCU, 16 MHz, 1 KB Flash, 128 B RAM, 8-ch 10-bit ADC, I²C/SPI, 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":"MSP430G2131","Program Memory Size":"1KB (1K 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/fa8d4e371cab55492ccab559153f4d10.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430G2131IPW4Q1/alternatives.json"},"ai":{"faq":[{"question":"Is MSP430G2131IPW4Q1 obsolete?","answer":"Yes, the MSP430G2131IPW4Q1 is listed as Obsolete.
