The 12K x 8 RAM provides working space for moderate-sized buffers and stacks. ## I/O and peripheral mix for sensor and control loops With 44 I/O lines, this MCU can handle a mix of digital sensors, keypad matrices, and control outputs without an external port expander. The integrated 9-channel 12-bit SAR ADC covers analog inputs like thermistors or current shunts. Connectivity includes IrDA, SCI, SPI, and UART/USART, so it can talk to serial peripherals, wireless modules, or a host controller. Brown-out detect and POR keep the system from locking up on a droopy supply rail. ## Supply and temperature — industrial floor ready The 64-VFQFN package with exposed pad helps pull heat out through the PCB ground plane — important if the MCU is driving several outputs simultaneously.","metaTitle":"TI MSP430FR50431IRGCT 16-Bit MCU, 64KB FRAM, 16MHz, 64-VQFN","metaDescription":"Texas Instruments MSP430FR50431IRGCT 16-bit MCU with MSP430 CPUXV2 core, 64KB FRAM, 12K x 8 RAM, 16MHz speed, 44 I/O, 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":"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":"MSP430FR50431","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":[{"question":"What package type is MSP430FR50431IRGCT?","answer":"It comes in a 64-VFQFN exposed pad package, with the supplier device package listed as 64-VQFN (9x9).
