There is no room for a full RTOS or a complex protocol stack — think a dedicated sensor interface, a small actuator controller, or a simple LIN slave node. The 128 bytes of RAM handle a few variables and a modest call stack; any significant data buffering needs to be managed in Flash or streamed out over the serial interface. ## Automotive AEC-Q100 qualification — the real differentiator This is the same MSP430G2 core used in countless consumer and industrial designs, but with the added reliability screening that automotive OEMs and tier-1 suppliers require. ## 16-QFN package — layout and thermal notes The 10 I/O pins plus the dedicated supply and ground pins leave limited room for external components — plan for a 100 nF decoupling capacitor close to each supply pin.","metaTitle":"TI MSP430G2231IRSARQ1 16-Bit MCU, 16MHz, 2KB Flash, AEC-Q100","metaDescription":"Texas Instruments MSP430G2231IRSARQ1 automotive 16-bit MCU: 16MHz MSP430 CPU16, 2KB Flash, 128B RAM, 8ch 10-bit ADC, I²C/SPI, -40°C to 85°C, 16-QFN.","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":"Automotive, AEC-Q100, MSP430G2","Package":"Tape & Reel (TR)","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":"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/09a2c6e980ce06988e69e19f0f9ff253.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430G2231IRSARQ1/alternatives.json"},"ai":{"faq":[{"question":"What are the specifications of MSP430G2231IRSARQ1?","answer":"This is a 16-bit MSP430 CPU16 microcontroller running at 16 MHz.

It offers 8 KB of Flash and 512 bytes of RAM versus the MSP430G2231's 2 KB Flash and 128 bytes RAM. The G2452 also includes a 16-bit sigma-delta ADC and a comparator, while the G2231 has a 10-bit SAR ADC. Both run at 16 MHz and share the same 16-pin QFN footprint, but the G2452 requires a larger firmware budget and costs more per unit."},{"question":"Is MSP430G2231IRSARQ1 RoHS compliant?","answer":"Yes, the MSP430G2231IRSARQ1 is RoHS compliant.
