On-chip peripherals include a power-on reset (POR) and watchdog timer (WDT), plus a slope A/D converter for low-resolution analog measurements without an external ADC. The 14 general-purpose I/O lines are available in the 20-TSSOP package, which occupies a compact 4.40 mm width footprint on the board. This means Texas Instruments has flagged it for eventual discontinuation; new design-ins should target a current-production MSP430 derivative.","metaTitle":"Texas Instruments MSP430F1121IPWR 16-bit MCU, 8 MHz","metaDescription":"Texas Instruments MSP430F1121IPWR 16-bit MCU, 8 MHz core, 4 KB Flash, 256 x 8 RAM, -40°C to 85°C, 20-TSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"8MHz","Series":"MSP430x1xx","Package":"Tape & Reel (TR)","RAM Size":"256 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-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Not For New Designs","Data Converters":"Slope A/D","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F1121","Program Memory Size":"4KB (4K x 8 + 256B)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"20-TSSOP","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.4793","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a4aeb7aaa72cf31b8760cd29d65bbd49.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F1121IPWR/alternatives.json"},"ai":{"faq":[{"question":"Is MSP430F1121IPWR obsolete or NRND?","answer":"It is not yet discontinued, but Texas Instruments recommends against using it in new designs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430F1121IPWR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430F1121IPWR when reusing this data.
