The FRAM gives you non-volatile storage that writes at near-SRAM speed and draws negligible power in standby — no wear-leveling needed for frequent data logging or configuration updates. ## FRAM memory — why it changes the firmware strategy The 64 KB FRAM program memory is the standout feature. Unlike Flash, FRAM writes at bus speed with no erase-before-write penalty, and it retains data without a battery. For a field-updated device — say a gas meter that logs consumption and receives OTA firmware patches — you can treat the FRAM as both code store and data log without sector management. Endurance is effectively unlimited for practical product lifetimes, so no wear-leveling algorithm is needed in the application layer. ## Package and footprint for the rework bench The part comes in a 64-VFQFN with exposed pad (9x9 mm body). The pad is also the primary GND return for the core, so the datasheet layout guidelines matter for both thermal and signal integrity. ## Supply voltage and serial interfaces The 9-channel 12-bit SAR ADC is good for monitoring sensor voltages, battery level, or current shunt signals. ## Lifecycle status — active and available for new designs No last-time-buy or phase-out notice applies. The base product number is MSP430FR5043, and the IRGCT suffix denotes the tape-and-reel shipping.","metaTitle":"Texas Instruments MSP430FR5043IRGCT 16-bit MCU, 16 MHz","metaDescription":"Texas Instruments MSP430FR5043IRGCT 16-bit MSP430 CPUXV2 MCU with 64 KB FRAM, 12K x 8 RAM, 16 MHz speed, 44 I/O, -40 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":"12K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"IrDA, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"44","Core Processor":"MSP430 CPUXV2","Package / Case":"64-VFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 9x12b SAR","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR5043","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":"$8.7842","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/61611b0ff4b6eb004fd8ed6f663659b7.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430FR5043IRGCT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430FR5043IRGCT when reusing this data.
