That means you can treat the FRAM as both code store and data-logging space without wear-leveling overhead. The 2K x 8 RAM handles stack and scratchpad. ## 63 I/O and peripheral set for sensor-heavy designs The integrated 12-channel 12-bit ADC handles analog inputs directly. Brown-out detect, POR, DMA, and a watchdog timer are on-chip, reducing external BOM count.","metaTitle":"MSP430FR68891IPNR 16-Bit MCU, 128KB FRAM, 16MHz, 80-LQFP","metaDescription":"Texas Instruments MSP430FR68891IPNR 16-bit MCU with 128KB FRAM, 16MHz core, 63 I/O, 12x12b ADC, -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, 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":"$5.2682","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9187a028bbd152fbe272241f049cad0b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MSP430FR68891IPNR compatible with existing MSP430 low-power designs?","answer":"Yes. The MSP430FR68891IPNR uses the same MSP430 CPUXV2 core and peripheral set as other MSP430 FRAM series devices. Code written for MSP430F series parts may need minor porting due to FRAM timing differences, but the low-power modes (LPM0–LPM4) and clock tree are consistent across the family."},{"question":"What are the key differences between MSP430FR68891IPNR and MSP430FR68791IPNR?","answer":"The primary difference is program memory density: the MSP430FR68891IPNR has 128 KB of FRAM, while the MSP430FR68791IPNR has 64 KB. Both share the same 80-LQFP package, 63 I/O, 16 MHz core, and peripheral set. The 128 KB variant is the choice for larger firmware images or data-logging buffers."},{"question":"Can MSP430FR68891IPNR be used in automotive or industrial temperature ranges?","answer":"It is not AEC-Q100 qualified, so it is not recommended for under-hood automotive applications. For industrial control, outdoor telecom, and factory automation, the temperature grade is appropriate."},{"question":"What development tools are supported for programming MSP430FR68891IPNR?","answer":"The MSP430FR68891IPNR is programmed and debugged via the standard Spy-Bi-Wire (SBW) interface, supported by TI's MSP-FET programmer, the LaunchPad development kits, and third-party tools like the Segger J-Link. Code Composer Studio and IAR Embedded Workbench are the primary IDEs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430FR68891IPNR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430FR68891IPNR when reusing this data.
