FRAM writes at bus speed with no erase cycle, draws negligible write current, and is rated for effectively unlimited endurance — no wear-leveling needed for frequent data logging or configuration updates. The 1 KB SRAM is modest, sized for small buffers and stack. The 21 I/O lines bring out I²C, SPI, UART, and LINbus connectivity, enough for sensor nodes, metering, and simple control loops. That means no last-time-buy window to manage, no end-of-life risk for a design starting today. TI continues to support this part with datasheets, application notes, and the MSP430Ware software library. For BOM planning, this is a low-risk line item that can be dual-sourced through independent distribution without obsolescence contingency. ## Sourcing posture For a production BOM or a prototype run, the procurement step is straightforward: submit an RFQ with quantity and target date.","metaTitle":"TI MSP430FR5722IPW 16-bit MCU, 8KB FRAM, 8MHz, 28-TSSOP","metaDescription":"Texas Instruments MSP430FR5722IPW 16-bit MCU with 8KB FRAM, 1KB SRAM, 8MHz core, 21 I/O, I²C/SPI/UART, -40°C to 85°C, 28-TSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"8MHz","Series":"MSP430™ FRAM","Package":"Tube","RAM Size":"1K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"21","Core Processor":"MSP430 CPUXV2","Package / Case":"28-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Active","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR5722","Program Memory Size":"8KB (8K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"28-TSSOP","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.0584","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1a28c1961c44971ab8214ed18f61603a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the alternatives to MSP430FR5722IPW?","answer":"Within the MSP430 FRAM family, the closest pin-compatible alternative is the MSP430FR5720IPW, which offers the same 28-TSSOP footprint and peripheral set but with 4 KB FRAM instead of 8 KB.
