If you are designing a new board, do not spec this code; look for a current MSP430FRxx variant with equivalent FRAM density and peripheral set. ## Peripheral set and connectivity for a mixed-signal control node The MSP430FR58891IRGCR integrates a brown-out detect and reset, POR, DMA controller, PWM timers, and a watchdog timer — the usual set for an autonomous sensor or actuator controller. ## 64-VFQFN — footprint and thermal reality The package is a 64-lead VFQFN with an exposed pad, 9x9 mm body (64-VQFN per the supplier device code).","metaTitle":"TI MSP430FR58891IRGCR 16-bit MCU, 128KB FRAM, 16MHz, 48 I/O","metaDescription":"Texas Instruments MSP430FR58891IRGCR 16-bit MCU with 128KB FRAM, 2KB SRAM, 16MHz CPUXV2 core, 48 I/O, 12-bit ADC, 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)","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/MSP430FR58891IRGCR/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for MSP430FR58891IRGCR?","answer":"Texas Instruments has not published a direct pin-compatible successor for the MSP430FR58891IRGCR. For a new design, look at current MSP430FRxx family members with similar FRAM density (128 KB) and peripheral set — the MSP430FR599x or MSP430FR604x series, for example, offer comparable or expanded capability in the same 64-QFN footprint.
