The device integrates 4K x 8 of SRAM, an 8-channel 10-bit ADC, and serial interfaces including I²C, SPI, and UART. ## FRAM advantage: unified memory with fast writes and high endurance The 15.5 KB FRAM program memory is the standout feature of this part. Unlike Flash-based MCUs where a sector erase can take tens of milliseconds, FRAM writes at the bus speed — typically under 100 ns per byte — with no erase cycle required. Endurance is rated at 10^15 write cycles, effectively unlimited for most embedded applications. This makes the MSP430FR2633IRHBR a natural fit for data-logging nodes, configuration storage, and any design where the MCU must update its own code or calibration constants in the field without wearing out the memory. ## Peripheral set and I/O for compact control boards With 19 general-purpose I/O pins, an 8-channel 10-bit ADC, and serial connectivity covering I²C, SPI, UART, and IrDA, this MCU can handle a typical sensor-to-communication bridge without external glue logic. ## Package and thermal: 32-VQFN with exposed pad The 32-VQFN (5x5 mm) package with exposed thermal pad is the only package option for this ordering code. The supplier device package is 32-VQFN (5x5), so the PCB footprint is consistent across the MSP430FR2633 family. It is ROHS3 compliant.","metaTitle":"TI MSP430FR2633IRHBR 16-bit MCU, 16MHz, 15.5KB FRAM, 32-VQFN","metaDescription":"Texas Instruments MSP430FR2633IRHBR 16-bit MCU with 16MHz core, 15.5KB FRAM, 4K x 8 RAM, 8x10b ADC, I²C/SPI/UART, -40°C to 85°C, 32-VQFN.","metaKeywords":null},"attributes":{"series":"MSP430™ FRAM","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"16MHz","Series":"MSP430™ FRAM","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"4K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, IrDA, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"19","Core Processor":"MSP430 CPU16","Package / Case":"32-VFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR2633","Program Memory Size":"15.5KB (15.5K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"32-VQFN (5x5)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.8600","priceTiers":[{"qty":1,"price":"$5.86000","currency":"USD"},{"qty":10,"price":"$5.26100","currency":"USD"},{"qty":25,"price":"$4.97360","currency":"USD"},{"qty":100,"price":"$4.31030","currency":"USD"},{"qty":250,"price":"$4.08924","currency":"USD"},{"qty":500,"price":"$3.66926","currency":"USD"},{"qty":1000,"price":"$3.09456","currency":"USD"},{"qty":3000,"price":"$2.93983","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/98de76b2dca505a428b80203f1355665.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430FR2633IRHBR/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430FR2633IRHBR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430FR2633IRHBR when reusing this data.
