On-chip RAM is 2K x 8. Connectivity covers I²C, IrDA, SCI, SPI, and UART/USART. The 51 general-purpose I/O lines give plenty of headroom for sensor arrays, keypads, and control signals. ## FRAM vs Flash — what the memory type means The 32 KB FRAM program memory is the standout feature. FRAM writes at bus speed with no erase cycle, so firmware updates over UART or SPI complete in milliseconds rather than the hundreds of milliseconds a Flash part would need for a sector erase. Endurance is effectively unlimited for data logging (10^15 cycles typical), though TI rates it for the application lifetime.","metaTitle":"TI MSP430FR5870IRGCR 16-bit MCU, 16 MHz, 32 KB FRAM, 64-VQFN","metaDescription":"Texas Instruments MSP430FR5870IRGCR 16-bit MCU with MSP430 CPUXV2 core, 16 MHz speed, 32 KB FRAM, 2K x 8 RAM, 51 I/O, 8x12b ADC, -40°C to 85°C, 1.8V-3.6V","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":"MSP430FR5870","Program Memory Size":"32KB (32K 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":"$2.5281","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/62cf1d6e552ec626b1671d3557050635.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How does MSP430FR5870IRGCR compare to MSP430FR5870IPZ?","answer":"Both share the same core, memory, and peripheral set. The difference is the package: MSP430FR5870IRGCR is in a 64-VFQFN (9x9 mm, exposed pad), while MSP430FR5870IPZ is in a 64-LQFP. The QFN variant saves board area and offers better thermal performance through the paddle, but requires a more careful reflow profile and post-assembly inspection."},{"question":"What is the maximum clock speed of MSP430FR5870IRGCR?","answer":"The core runs at 16 MHz.
