Unlike Flash-based MCUs that wear out after 10,000 to 100,000 erase/write cycles, FRAM can handle over 10¹⁵ write cycles — effectively unlimited for any practical product lifetime. Write operations also consume less energy per byte than Flash, which matters for battery-powered designs that log data frequently. The 8KB size is enough for a modest firmware stack handling sensor reads, communication protocol framing, and state-machine control. For applications that need more code space, TI offers higher-density FRAM variants in the same MSP430FR57xx family. ## 38-TSSOP package and supply range The MSP430FR5723IDAR is supplied in a 38-TSSOP package (0.240\", 6.10mm width), a surface-mount footprint common in space-constrained industrial PCBs. The 30 I/O lines provide enough headroom for a keypad, LED indicators, and a parallel LCD interface alongside the serial buses. ## Obsolete — plan for replacement or last-time-buy Buyers should immediately evaluate a pin-compatible replacement within the MSP430FR57xx family or a higher-density FRAM variant to avoid a production gap.","metaTitle":"Texas Instruments MSP430FR5723IDAR 16-bit MCU, 8KB FRAM","metaDescription":"Texas Instruments MSP430FR5723IDAR 16-bit MCU with 8KB FRAM, 1KB SRAM, 8MHz core, 30 I/O, I²C/SPI/UART, -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":"8MHz","Series":"MSP430™ FRAM","Package":"Tape & Reel (TR)","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":"30","Core Processor":"MSP430 CPUXV2","Package / Case":"38-TSSOP (0.240\\\", 6.10mm Width)","Product Status":"Obsolete","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR5723","Program Memory Size":"8KB (8K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"38-TSSOP","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bb2d5c5985d116db41e2130cffa793fd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430FR5723IDAR/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for MSP430FR5723IDAR?","answer":"The base product number is MSP430FR5723.
