The 2 KB SRAM (2K x 8) handles stack and scratchpad data. With 51 general-purpose I/O lines, an internal oscillator, and a 12-bit ADC with eight multiplexed channels, this part targets sensor fusion nodes, metering, and industrial control loops where low power and deterministic write performance matter. ## Supply range and power rail design Dropout margin at the low end is tight — if the supply dips below 1.8 V the brown-out detect (BOD) resets the core cleanly. The POR and BOD peripherals are integrated, so no external supervisor is needed for most designs. It suits outdoor telecom cabinets, factory-floor sensor nodes, motor-drive control boards, and under-hood automotive auxiliary modules (non-safety-rated). ## Peripherals and connectivity On-chip peripherals include a DMA controller for memory-to-peripheral transfers without CPU loading, PWM timers for motor or LED drive, and a watchdog timer. The 12-bit ADC with eight channels samples at rates adequate for slow-loop feedback (temperature, pressure, current sense).","metaTitle":"MSP430FR59221IRGCR 16-bit MCU, 64KB FRAM, 16MHz, 51 I/O","metaDescription":"Texas Instruments MSP430FR59221IRGCR 16-bit MCU with 64KB FRAM, 2KB SRAM, 16MHz CPU, 51 I/O, 8x12b ADC, -40°C 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":"MSP430FR59221","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":"$3.2878","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9f010409eb91c6126c5c33c725f90056.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the differences between MSP430FR59221IRGCR and MSP430FR59221IRGC?","answer":"The suffix 'R' in MSP430FR59221IRGCR indicates Tape & Reel packaging, while MSP430FR59221IRGC ships in a different reel or tray variant.
