The 2K x 8 RAM handles stack and scratchpad. On the analog side you get a 14-channel 12-bit ADC, enough for a multi-sensor input stage without external muxing. ## FRAM vs Flash — why it matters for field updates The 48 KB FRAM program memory is the headline feature. Unlike Flash, FRAM writes at bus speed with no erase-before-write penalty and endures over 10^15 write cycles per byte. That means you can log data or update firmware in the field without an external EEPROM and without wear-leveling logic in software. For a product that ships once and gets OTA updates for years, this saves BOM cost and firmware complexity. ## Package and footprint — what the rework tech sees The MSP430FR5858IRHAR comes in a 40-VFQFN with an exposed thermal pad (40-VQFN 6x6 mm per the supplier device package). The pad needs a via stitch to the ground plane for thermal relief; without it, continuous current above 400 mA on the I/O rails can push junction temperature past the 85°C limit. The pad orientation is marked by pin 1 chamfer, so a quick visual check on site is enough to get it right. ## Lifecycle and supply posture That means standard lead times through distribution, no LTB math needed, and full manufacturer support for new designs.","metaTitle":"TI MSP430FR5858IRHAR 16-bit MCU, 48KB FRAM, 16MHz, 40-VQFN","metaDescription":"Texas Instruments MSP430FR5858IRHAR 16-bit MCU with 48KB FRAM, 16MHz CPU, 14x12b ADC, industrial temp -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":"33","Core Processor":"MSP430 CPUXV2","Package / Case":"40-VFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 14x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR5858","Program Memory Size":"48KB (48K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"40-VQFN (6x6)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.9159","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/662f6d7793fada84e8ff14acce90914f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to MSP430FR5858IRHAR?","answer":"The record does not list a direct pin-compatible second source.
