The 2 KB of conventional RAM handles stack and scratchpad data. At the low end, 1.8 V is the minimum for FRAM read/write integrity — a brown-out detector (included in the peripheral set) resets the core if the rail dips below that threshold.","metaTitle":"MSP430FR68891IPN Texas Instruments 16-bit MCU, 128KB FRAM","metaDescription":"MSP430FR68891IPN 16-bit MCU with 128KB FRAM, 2KB RAM, 63 I/O, 12x12b ADC, I²C/SPI/UART, -40°C to 85°C, 1.8V-3.6V.","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":"Tube","RAM Size":"2K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"63","Core Processor":"MSP430 CPUXV2","Package / Case":"80-LQFP","Product Status":"Active","Data Converters":"A/D 12x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR68891","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"80-LQFP (12x12)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.3347","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9187a028bbd152fbe272241f049cad0b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to MSP430FR68891IPN in this component family?","answer":"Within the MSP430 FRAM family, the base product number MSP430FR68891 defines the 128 KB FRAM and 80-LQFP footprint.
