The 2K x 8 RAM handles scratchpad and stack. This part carries an Obsolete lifecycle status. ## Connectivity and data conversion The MCU includes I²C, IrDA, SPI, and UART/USART interfaces, covering the common serial buses for sensor hubs, displays, and module communication. A 12-channel, 12-bit ADC is on-chip for analog inputs — enough for most single-ended sensor readouts without an external converter. ## Package and mounting Housed in a 64-VFQFN with exposed pad (supplier package 64-VQFN, 9x9 mm), this is a surface-mount part.","metaTitle":"TI MSP430FR59891IRGCR 16-bit MCU, 128KB FRAM, 16MHz, 64-VQFN","metaDescription":"Texas Instruments MSP430FR59891IRGCR 16-bit MCU with 128KB FRAM, 16MHz core, 48 I/O, -40°C to 85°C.","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, 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":"MSP430FR59891","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":"$10.5900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/55a2283ae83caa6f52fa523536a83a25.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for MSP430FR59891IRGCR?","answer":"For a new design, consider current MSP430 FRAM family MCUs in the same 64-VQFN package — expect differences in peripheral set and memory map that require a firmware port."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430FR59891IRGCR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430FR59891IRGCR when reusing this data.
