Production has ended; no last-time-buy window remains. This part is available only through surplus and independent distribution channels. For a new design or a production line that needs a guaranteed supply, an official replacement should be identified. ## 128 KB FRAM — the key differentiator This MCU uses 128 KB of FRAM (ferroelectric RAM) for program memory, backed by 2 KB of conventional SRAM. FRAM combines non-volatility with fast write speeds and near-infinite endurance — no wear-leveling needed for frequent data logging or configuration updates. The 16-bit CPUXV2 core runs at 16 MHz, enough for sensor fusion, metering, or low-power control loops. ## Peripheral set and I/O An integrated 12-channel, 12-bit ADC handles analog inputs. The internal oscillator reduces external component count. ## Supply and temperature range Packaged in a 64-LQFP (10×10 mm) surface-mount package.","metaTitle":"MSP430FR59891IPMR 16-bit MCU, 16MHz, 128KB FRAM, 64-LQFP","metaDescription":"Texas Instruments MSP430FR59891IPMR 16-bit MCU with 16MHz CPUXV2, 128KB FRAM, 2KB RAM, 48 I/O, 12-bit ADC, I²C/SPI/UART.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"16MHz","title":"MSP430FR59891IPMR","Series":"MSP430™ FRAM","Package":"Tape & Reel (TR)","RAM Size":"2K x 8","Core Size":"16-Bit","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-LQFP","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-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.9203","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/55a2283ae83caa6f52fa523536a83a25.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MSP430FR59891IPMR obsolete?","answer":"Yes, the MSP430FR59891IPMR is listed as Obsolete.
