The 87 I/O pins in the 100-LQFP package give you room for parallel LCD interfaces, multiple UARTs, and a bank of GPIOs without muxing conflicts. ## Supply range and temperature — where it runs ## Peripherals and connectivity — what the bus carries DMA moves data between peripherals and RAM without CPU intervention, which matters when you're running the ADC at full rate and still need to service the protocol stack. ## Lifecycle — no LTB surprise for production For dual-source planning, the MSP430F5xx family includes pin-compatible density variants — stepping up or down in Flash/RAM without a board spin is possible within the same footprint.","metaTitle":"MSP430F5438AIPZR 16-bit MCU, 25 MHz, 256 KB Flash, 100-LQFP","metaDescription":"Texas Instruments MSP430F5438AIPZR 16-bit MCU with MSP430 CPUXV2 core at 25 MHz, 256 KB Flash, 16 KB RAM, 87 I/O, industrial temp -40°C to 85°C, 100-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"25MHz","Series":"MSP430F5xx","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"16K 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","Mounting Type":"Surface Mount","Number of I/O":"87","Core Processor":"MSP430 CPUXV2","Package / Case":"100-LQFP","Product Status":"Active","Data Converters":"A/D 16x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F5438","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":"$10.2800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/33c817039da93b53b05fbf53855659ed.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F5438AIPZR/alternatives.json"},"ai":{"faq":[{"question":"Is MSP430F5438AIPZR equivalent to MSP430F5438?","answer":"MSP430F5438 is the base product number.
