FRAM writes at near-SRAM speed, consumes far less active power per write than Flash, and tolerates 10^15 write cycles — no erase-before-write penalty, no wear-leveling firmware needed. Combined with 8 KB of conventional SRAM, this memory architecture suits data-logging, over-the-air firmware updates, and any application where the MCU wakes, writes a record, and goes back to sleep without waiting on a Flash page erase. ## Supply range and battery-fit That matters for the bill of materials count and for quiescent current in always-on sense nodes. ## Peripheral set for sensor fusion and control With 68 general-purpose I/O lines, a 20-channel 12-bit ADC, and serial interfaces covering I²C, SPI, UART, and IrDA, this MCU can handle multi-sensor aggregation, display driving, and a modest control loop without external glue logic. The built-in brown-out detect, POR, DMA, and PWM peripherals reduce external supervisor ICs and simplify the power-up sequencing. Both an external crystal and the internal oscillator are supported, so a low-cost RC-based clock is feasible for non-timing-critical code. ## Lifecycle and sourcing posture That means no supply-chain clock ticking for new designs or long-life BOMs.","metaTitle":"Texas Instruments MSP430FR5992IPNR MCU, 16-Bit 16MHz","metaDescription":"TI MSP430FR5992IPNR 16-bit MCU with 128KB FRAM, 8KB SRAM, 16MHz CPUXV2 core, 68 I/O, 20x12b ADC, 1.8-3.6V, -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":{"Speed":"16MHz","title":"MSP430FR5992IPNR","Series":"MSP430™ FRAM","Package":"Tape & Reel (TR)","RAM Size":"8K 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":"68","Core Processor":"MSP430 CPUXV2","Package / Case":"80-LQFP","Data Converters":"A/D 20x12b","Oscillator Type":"External, Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR5992","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"80-LQFP (12x12)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.5409","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/90a9615b5a41acf5f80ee73c939bea1e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between MSP430FR5992IPNR and MSP430FR5994IPNR?","answer":"The MSP430FR5994IPNR is the higher-density sibling in the same FRAM series, offering 256 KB FRAM and 32 KB SRAM versus the 128 KB FRAM and 8 KB SRAM on the MSP430FR5992IPNR. Both share the same 16 MHz CPUXV2 core, 80-LQFP package, peripheral set, and 1.8–3.6 V supply range.
