The 48 I/O include the LCD segment and common outputs, plus the ADC and DAC analog pins; the datasheet's pin assignment should be checked against the LCD glass layout early in the schematic phase to avoid a board spin.","metaTitle":"MSP430F477IPNR 16-bit MCU, 8 MHz, 32 KB Flash, 80-LQFP","metaDescription":"Texas Instruments MSP430F477IPNR 16-bit MCU with 8 MHz core, 32 KB Flash, 2K x 8 RAM, LCD driver, 5x16-bit ADC, 1x12-bit DAC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"8MHz","Series":"MSP430x4xx","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"2K x 8","Core Size":"16-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, LCD, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SCI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"48","Core Processor":"MSP430 CPU16","Package / Case":"80-LQFP","Product Status":"Active","Data Converters":"A/D 5x16b; D/A 1x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"MSP430F477","Program Memory Size":"32KB (32K x 8 + 256B)","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":"$8.2545","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2a12a9cec3fa4ae1bde1fe530182f33b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MSP430F477IPNR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between MSP430F477IPNR and MSP430F477IPM?","answer":"The MSP430F477IPNR and MSP430F477IPM share the same core, memory, and peripheral set — the difference is the package. The IPNR variant is an 80-LQFP, while the IPM variant is a 64-pin LQFP. The 80-pin package gives 48 I/O versus fewer on the 64-pin version, which matters when the design needs more LCD segment lines or parallel bus signals."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430F477IPNR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430F477IPNR when reusing this data.
