This is a part for simple, battery-aware control tasks: sensor polling, relay timing, keypad scanning, or basic supervisory logic where every microamp counts. ## Memory and speed — what fits in 1 KB Flash and 128 bytes RAM At 8 MHz the CPU16 core delivers enough throughput for a few hundred lines of C or a tight assembly loop. The 1 KB Flash is the hard constraint: a UART bootloader, a PID loop, and a Modbus frame handler will not all fit. Plan for a single-purpose firmware image — a thermostat state machine, a simple timer, or a one-wire sensor reader. The 128-byte RAM forces careful variable allocation; stack depth beyond a few calls and a handful of locals will overflow. Use the 256-byte information memory (part of the Flash array) for calibration constants that survive power loss. ## Supply voltage and temperature — field-fit check Not rated for under-hood automotive or downhole drilling, but fine for a solar-powered irrigation controller or a parking-lot light sensor. Housed in a 20-pin SOIC wide-body (0.295-inch width, 7.50 mm), this is a hand-solderable package — no hot-air station needed for rework. The 14 I/O pins are enough for a few LEDs, a pushbutton, a serial interface, and an analog input. No exposed pad, no thermal via stitching — just a straightforward two-layer board layout. ## Lifecycle and sourcing — still in active production It is ROHS3 compliant.","metaTitle":"Texas Instruments MSP430F1101AIDWR 16-bit MCU, 8 MHz","metaDescription":"Texas Instruments MSP430F1101AIDWR 16-bit MCU with 8 MHz core, 1 KB Flash, 128 B RAM, 14 I/O, industrial temp -40°C to 85°C, 20-SOIC.","metaKeywords":null},"attributes":{"series":"MSP430x1xx","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"8MHz","Series":"MSP430x1xx","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"128 x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"POR, WDT","Connectivity":"-","Mounting Type":"Surface Mount","Number of I/O":"14","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":"MSP430F1101","Program Memory Size":"1KB (1K x 8 + 256B)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"20-SOIC","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.0100","priceTiers":[{"qty":1,"price":"$4.01000","currency":"USD"},{"qty":10,"price":"$3.59900","currency":"USD"},{"qty":25,"price":"$3.40200","currency":"USD"},{"qty":100,"price":"$2.94840","currency":"USD"},{"qty":250,"price":"$2.79720","currency":"USD"},{"qty":500,"price":"$2.50992","currency":"USD"},{"qty":1000,"price":"$2.11680","currency":"USD"},{"qty":2000,"price":"$2.01096","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/0c04dfb355e64c178c344f177e3b6cc8.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F1101AIDWR/alternatives.json"},"ai":{"faq":[{"question":"Is MSP430F1101AIDWR RoHS compliant?","answer":"Yes, it is rated ROHS3 compliant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430F1101AIDWR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430F1101AIDWR when reusing this data.
