The 74 general-purpose I/Os in the 100-LQFP package give plenty of headroom for parallel displays, keypads, or control signals. ## Temperature range and supply — environment check The brown-out detect and POR circuitry keeps the core from misbehaving during power-up and brown-out events — useful in noisy industrial environments. ## Lifecycle and sourcing — still a current choice There is no last-time-buy clock ticking, and no forced migration to a newer part. For dual-sourcing or supply resilience, the MSP430F5xx family includes several pin-compatible siblings with varying Flash and RAM sizes — the exact alternative depends on your memory budget and peripheral set.","metaTitle":"MSP430F5638IPZR 16-bit MCU, 20 MHz, 256 KB Flash, 100-LQFP","metaDescription":"Texas Instruments MSP430F5638IPZR 16-bit MCU with MSP430 CPUXV2 core at 20 MHz, 256 KB Flash, 18 KB RAM, USB and serial connectivity, industrial temp range -40","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"20MHz","Series":"MSP430F5xx","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"18K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SCI, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"74","Core Processor":"MSP430 CPUXV2","Package / Case":"100-LQFP","Product Status":"Active","Data Converters":"A/D 16x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F5638","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.0100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d0f0be01b1fb6b2469fb4f76de7d1e17.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to MSP430F5638IPZR?","answer":"Within the MSP430F5xx family, parts with the same 100-LQFP footprint and similar peripheral sets include the MSP430F5659 (higher Flash/RAM) and MSP430F5637 (lower Flash/RAM).
