That means firmware updates can be done byte-by-byte without the erase-then-write penalty of Flash, and data logging can hammer the same address without wear-leveling. The 2K x 8 SRAM handles stack and scratchpad. ## 16 MHz CPU speed — enough for what? The 16 MHz clock rate is modest by today's MCU standards, but it's typical for the MSP430 ultra-low-power line. This part is aimed at battery-powered sensing, metering, and human-interface applications where throughput is secondary to energy efficiency. The peripheral list includes a segment LCD driver, brown-out detect, POR, PWM, WDT, DMA, and an 8-channel 12-bit ADC. The 46 I/O in a 56-TSSOP package gives good pin density for a mixed-signal control board. That means no last-time-buy notice is in effect, and the part is still supported for new designs.","metaTitle":"Texas Instruments MSP430FR69221IG56R 16-bit MCU, 64KB FRAM","metaDescription":"TI MSP430FR69221IG56R 16-bit MCU with 64KB FRAM, 16MHz CPU, 2K x 8 RAM, 46 I/O, LCD driver, -40°C to 85°C, 56-TSSOP.","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, LCD, POR, PWM, WDT","Connectivity":"I²C, IrDA, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"46","Core Processor":"MSP430 CPUXV2","Package / Case":"56-TFSOP (0.240\\\", 6.10mm Width)","Product Status":"Active","Data Converters":"A/D 8x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR69221","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"56-TSSOP","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.2942","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/379bdbaef1c08b290b77ed7b15d84b9f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the FRAM size of MSP430FR69221IG56R?","answer":"64 KB (64K x 8) of FRAM program memory, which is non-volatile, byte-addressable, and requires no erase cycle before writes."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430FR69221IG56R","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430FR69221IG56R when reusing this data.
