The 63 I/O pins in an 80-LQFP package give you enough GPIO for a keypad, display, and a handful of external peripherals without needing a port expander. The connectivity block includes USB 2.0 (full-speed, 12 Mbps) alongside I²C, SPI, UART, IrDA, and LINbus. That USB peripheral is the main differentiator versus lower-cost MSP430G2xx parts — it saves an external USB-to-UART bridge chip and the associated firmware overhead. The integrated PHY and transceiver mean the BOM stays tight: just a 1.5 kΩ pull-up on D+ and a few passives. No external oscillator needed either — the internal oscillator runs the USB clock, though a crystal improves jitter margin if you are pushing the 25 MHz core to its limit. ## Lifecycle status — no LTB risk That means no last-time-buy notice pending, no end-of-life clock ticking. It is a safe line item for both new production runs and long-term sustaining builds.","metaTitle":"TI MSP430F5519IPNR 16-bit MCU, 25 MHz, 128 KB Flash, USB","metaDescription":"Texas Instruments MSP430F5519IPNR 16-bit MCU with MSP430 CPUXV2 core at 25 MHz, 128 KB Flash, 10 KB RAM, USB 2.0, 63 I/O, -40°C to 85°C, 80-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":"10K 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":"63","Core Processor":"MSP430 CPUXV2","Package / Case":"80-LQFP","Product Status":"Active","Data Converters":"-","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F5519","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"80-LQFP (12x12)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.1600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2e95dc6e7be321ead419de6523f16065.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F5519IPNR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between MSP430F5519IPNR and MSP430F5519IPN?","answer":"The two parts are electrically identical — same 25 MHz core, 128 KB Flash, 10 KB RAM, USB, and 80-LQFP package.
