The Slope A/D converter provides a basic analog measurement path without requiring an external ADC — enough for thermistor or potentiometer readout in a control loop. That means no last-time-buy scramble for repair stock or new-design qualification.","metaTitle":"MSP430F2131TDWR 16-bit MCU, 16 MHz, 8 KB Flash, 20-SOIC","metaDescription":"Texas Instruments MSP430F2131TDWR 16-bit MSP430 CPU16 MCU at 16 MHz, 8 KB Flash, 256-byte RAM, 1.8 V to 3.6 V supply, 20-SOIC, -40 to 105 °C.","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":"MSP430F2xx","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"256 x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"-","Mounting Type":"Surface Mount","Number of I/O":"16","Core Processor":"MSP430 CPU16","Package / Case":"20-SOIC (0.295\\\", 7.50mm Width)","Product Status":"Active","Data Converters":"Slope A/D","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F2131","Program Memory Size":"8KB (8K x 8 + 256B)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~105°C(TA)","Supplier Device Package":"20-SOIC","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0110","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/915f3387ecbce04a8fd7c7e9a4da9617.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F2131TDWR/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the MSP430F2131TDWR and what is the lead time?","answer":"The MSP430F2131TDWR is sourced to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.
