Housed in a 64-pin VFQFN with an exposed pad (9x9 mm) — hand-solderable with a hot-air station if you're careful, but the pad under the package needs a thermal via pattern for good solder wetting. ## Lifecycle reality — obsolete, but still sourced TI lists the MSP430FR58891IRGCT as obsolete. That means no new factory orders — no last-time-buy window, no direct replenishment. If you need a production-ready alternative, check the MSP430FR58891's sibling variants in the same family — they share the same core and peripheral set, though pin compatibility varies by package option.","metaTitle":"Texas Instruments MSP430FR58891IRGCT 16-bit MCU, 128KB FRAM","metaDescription":"Texas Instruments MSP430FR58891IRGCT 16-bit MCU with 128KB FRAM, 2KB RAM, 16MHz speed, 48 I/O, industrial temp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"16MHz","Series":"MSP430™ FRAM","Package":"Tape & Reel (TR); Cut Tape (CT)","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":"48","Core Processor":"MSP430 CPUXV2","Package / Case":"64-VFQFN Exposed Pad","Product Status":"Obsolete","Data Converters":"A/D 12x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR58891","Program Memory Size":"128KB (128K 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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d2b670fee89d13c5844b8166b8ab0bce.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430FR58891IRGCT/alternatives.json"},"ai":{"faq":[{"question":"Is MSP430FR58891IRGCT obsolete?","answer":"Yes, TI lists the MSP430FR58891IRGCT as obsolete.
