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 Internal oscillator is on-die, saving a crystal for most UART and PWM timing; the 16x12-bit ADC handles analog inputs without an external converter. ## Peripherals and connectivity — what the bus carries On the peripheral side you get I²C, SPI, UART/USART, LINbus, and IrDA — enough to talk to most sensor modules, motor drivers, and display controllers without glue logic. The brown-out detect and POR are integrated, so you skip the external supervisor on a single-supply design. 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","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/33c817039da93b53b05fbf53855659ed.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MSP430F5438AIPZR equivalent to MSP430F5438?","answer":"MSP430F5438 is the base product number.
