FRAM writes at bus speed with no erase cycle overhead, draws negligible write current, and is rated for endurance far beyond Flash — useful for data-logging applications that update non-volatile storage on every sensor read. The 2K x 8 SRAM handles stack and temporary variables; the 32KB FRAM serves double duty as both code store and data memory, so you can partition it between firmware and non-volatile data buffers without a separate EEPROM. ## Peripheral set for metering and display applications This MCU integrates an LCD driver, a 12-bit ADC with 8 channels, a brown-out reset circuit, DMA, PWM, and a watchdog timer. The 52 I/O lines in the 64-VFQFN package provide enough headroom for a keypad matrix, sensor interfaces, and a parallel LCD bus if needed. ## Connectivity and serial interfaces The IrDA support is less common on low-power MCUs and matters for IR data links in handheld terminals or optical isolation barriers. Operating from 1.8V to 3.6V, this part runs directly from two alkaline cells or a single Li-ion through its discharge curve. ## Lifecycle and sourcing posture Listed as Active by Texas Instruments, so there is no end-of-life clock ticking on this part. No second-source alternate is recorded in the available cross-reference data, so dual-sourcing would require a pin-compatible sibling within the MSP430FR6820 family — check the base product number MSP430FR6820 for other density or temperature variants.","metaTitle":"Texas Instruments MSP430FR6820IRGCR 16-bit MCU, 32KB FRAM","metaDescription":"MSP430FR6820IRGCR 16-bit MCU with 32KB FRAM, 2KB SRAM, 52 I/O, 8x12-bit ADC, LCD driver, -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, LCD, POR, PWM, WDT","Connectivity":"I²C, IrDA, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"52","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":"MSP430FR6820","Program Memory Size":"32KB (32K 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":"$2.5791","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1b4afe9c85f8080a11c9fe615135dd75.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest equivalent part for the MSP430FR6820IRGCR?","answer":"Within the MSP430FR6820 family, the base product number MSP430FR6820 covers multiple density and temperature variants sharing the same 64-VFQFN footprint.
