That makes it a fit for applications that log data or update configuration parameters frequently, where a Flash part would wear out or stall the write. The 512-byte SRAM is tight, so firmware needs to be lean — think simple state machines, sensor polling, or glue logic rather than a full protocol stack. ## Peripherals and I/O — what the 12 pins give you With 12 I/O lines and an internal oscillator, this MCU can handle basic control tasks without an external clock source. The peripheral set includes a 10-bit ADC with 8 multiplexed channels, plus IrDA, SCI, SPI, and UART/USART connectivity — enough for a single serial sensor interface or a simple wireless module link. Brown-out reset and POR are on-chip, so external supervisor ICs are optional for cost-sensitive boards.","metaTitle":"TI MSP430FR2100IRLLT 16-bit MCU, 1KB FRAM, 16MHz, 24-VQFN","metaDescription":"Texas Instruments MSP430FR2100IRLLT 16-bit MCU with 1KB FRAM, 512B SRAM, 16MHz CPU, 8x10b ADC, IrDA/SPI/UART, -40 to 85°C, 24-VQFN.","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); Cut Tape (CT)","RAM Size":"512 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":"12","Core Processor":"MSP430 CPU16","Package / Case":"24-VFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430FR2100","Program Memory Size":"1KB (1K x 8)","Program Memory Type":"FRAM","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"24-VQFN (3x3)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6bed1a0d746a6b3b1592703daef47f34.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to MSP430FR2100IRLLT in this component family?","answer":"Within the MSP430FR2100 series, the base product number MSP430FR2100 covers multiple package and temperature variants.
