That makes it a fit for data-logging applications where the MCU writes to its own code space frequently, or for over-the-air firmware updates where the erase-before-write penalty of Flash would stall the system. The 2K x 8 SRAM handles the stack and scratchpad for moderate-sized buffers. ## 51 I/O, I²C and SPI on the same die The integrated 8-channel 12-bit ADC (A/D 8x12b) covers analog sensor inputs directly. Internal oscillator means no external crystal is needed for the core clock, though one can be added for precision timing. ## Industrial temperature range and exposed-pad package Surface-mount only, MSL 3 handling — bake before reflow if the moisture barrier bag has been open past the floor-life window. TI lists the MSP430FR58721IRGCR as Active (current production). The base product number MSP430FR58721 covers a family of density and peripheral variants; if a design later needs more memory or a different peripheral mix, a pin-compatible sibling within the same FRAM series is the natural migration path.","metaTitle":"TI MSP430FR58721IRGCR 16-bit MCU, 64KB FRAM, 16 MHz, 51 I/O","metaDescription":"Texas Instruments MSP430FR58721IRGCR 16-bit MCU with 64KB FRAM, 16 MHz CPU, 51 I/O, I2C/SPI/UART, -40 to 85°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":"MSP430™ FRAM","Package":"Tape & Reel (TR)","RAM Size":"2K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"51","Core Processor":"MSP430 CPUXV2","Package / Case":"64-VFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 8x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR58721","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"64-VQFN (9x9)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.7726","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/62cf1d6e552ec626b1671d3557050635.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430FR58721IRGCR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430FR58721IRGCR when reusing this data.
