For sensor polling, control loops, or communication protocol handling, this sets the instruction throughput ceiling. ## Memory sizing: 16 KB Flash, 512 bytes RAM The 16 KB Flash is enough for modest firmware stacks — sensor fusion, simple control algorithms, or a communication protocol like Modbus RTU over UART. The 512-byte RAM is tight; you'll need to budget stack, global variables, and buffers carefully. Consider external EEPROM or a larger RAM part if your data set exceeds this. The 32 general-purpose I/O pins give you room for parallel interfacing or keypad scanning.","metaTitle":"MSP430F2254IRHAR 16-bit MCU, 16KB Flash, 16 MHz, 40-VQFN","metaDescription":"Texas Instruments MSP430F2254IRHAR 16-bit MCU with 16KB Flash, 512B RAM, 16 MHz, 12-ch 10-bit ADC, industrial temp -40°C to 85°C, ROHS3.","metaKeywords":null},"attributes":{"series":"MSP430F2xx","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"16MHz","Series":"MSP430F2xx","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":"I²C, IrDA, LINbus, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"32","Core Processor":"MSP430 CPU16","Package / Case":"40-VFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 12x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F2254","Program Memory Size":"16KB (16K x 8 + 256B)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"40-VQFN (6x6)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.6600","priceTiers":[{"qty":1,"price":"$7.66000","currency":"USD"},{"qty":10,"price":"$6.87700","currency":"USD"},{"qty":25,"price":"$6.50160","currency":"USD"},{"qty":100,"price":"$5.63470","currency":"USD"},{"qty":250,"price":"$5.34576","currency":"USD"},{"qty":500,"price":"$4.79674","currency":"USD"},{"qty":1000,"price":"$4.04544","currency":"USD"},{"qty":2500,"price":"$3.84317","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e53eff369abc185c8b143f576da16742.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F2254IRHAR/alternatives.json"},"ai":{"faq":[{"question":"Is the MSP430F2254IRHAR RoHS compliant?","answer":"Yes, it is ROHS3 compliant."},{"question":"What is the closest functional second-source for the MSP430F2254IRHAR?","answer":"The TI F280041PZQR is a different architecture (32-bit C28x) with higher speed (100 MHz), more memory, and automotive qualification, but it is not pin-compatible or a direct replacement.
