No erase cycles, no write-before-erase delays, and endurance rated orders of magnitude beyond typical Flash. For a firmware engineer, this means you can treat the code space like a data logger: update calibration tables, store system logs, or implement OTA staging without wear-leveling gymnastics. The 2 KB of conventional SRAM handles stack and scratchpad. ## 51 I/O and a full peripheral set in a 9x9 mm QFN With 51 I/O lines from a 64-VFQFN package (9x9 mm body, 0.5 mm pitch), this part packs a surprising number of signals into a compact footprint. The exposed thermal pad needs a via array under the die attach pad for both thermal relief and a solid ground return. Decoupling pairs of 0.1 µF and 1 µF ceramics per supply pin pair is the baseline; the internal LDO regulator for the core logic benefits from a 2.2 µF on Vcore if the datasheet app note calls for it. Peripheral set includes a brown-out reset, POR, DMA, PWM, and a watchdog timer — enough to build a self-monitoring controller without external supervisors. ## Industrial temperature range and active lifecycle The lifecycle status is Active — no NRND flags, no LTB window. The base product number MSP430FR5922 spans multiple package and temperature variants; the IRGCR suffix identifies this specific 64-pin QFN reel option. ## Connectivity and analog integration The 8-channel 12-bit ADC samples at rates suitable for single-cycle current sensing or temperature monitoring. An internal oscillator keeps the clock tree self-contained for cost-sensitive designs, though an external crystal can be routed through the dedicated pins for tighter timing.","metaTitle":"TI MSP430FR5922IRGCR 16-bit MCU, 64KB FRAM, 16MHz, 64-VQFN","metaDescription":"Texas Instruments MSP430FR5922IRGCR 16-bit MCU with 64KB FRAM, 2KB SRAM, 16MHz CPUXV2 core, 51 I/O, 8x12b ADC, industrial temp -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":{"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":"51","Core Processor":"MSP430 CPUXV2","Package / Case":"64-VFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 8x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR5922","Program Memory Size":"64KB (64K 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":"$3.2878","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9f010409eb91c6126c5c33c725f90056.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between MSP430FR5922IRGCR and MSP430FR5922?","answer":"MSP430FR5922 is the base product number covering the whole device family.
