It integrates a 12-bit ADC and two 8-bit DACs, plus serial interfaces covering I2C, SPI, UART/USART, and LINbus. ## What the 125°C rating buys you The 125°C rating covers engine-bay sensor nodes and outdoor telecom gear. ## Supply voltage flexibility and BOM simplification The 14-SOIC package fits a standard SOIC-14 land pattern — no fine-pitch reflow needed. ## Lifecycle status — current production, no LTB risk ROHS3 compliant.","metaTitle":"PIC18F04Q40-E/SL 8-Bit MCU, 64MHz, 16KB Flash, 14-SOIC","metaDescription":"Microchip PIC18F04Q40-E/SL 8-bit PIC MCU with 64MHz core, 16KB Flash, 1K x 8 RAM, 512 x 8 EEPROM, 1.8V-5.5V supply, -40°C to 125°C, 14-SOIC.","metaKeywords":null},"attributes":{"series":"PIC® 18F","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Microchip Technology","Speed":"64MHz","Series":"PIC® 18F","Package":"Tube","RAM Size":"1K x 8","Core Size":"8-Bit","EEPROM Size":"512 x 8","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I2C, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"12","Core Processor":"PIC","Package / Case":"14-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","Data Converters":"A/D 1x12b; D/A 2x8b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"PIC18F04Q40","Program Memory Size":"16KB (16K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"14-SOIC","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2200","priceTiers":[{"qty":1,"price":"$1.22000","currency":"USD"},{"qty":25,"price":"$1.11000","currency":"USD"},{"qty":100,"price":"$1.01000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ed6b62c2f5ecfa5811dadd968bc545aa.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/PIC18F04Q40-E%2FSL/alternatives.json"},"ai":{"faq":[{"question":"Can PIC18F04Q40-E/SL run from a 3.3V supply?","answer":"The internal oscillator and all peripherals operate at that voltage without external regulation."},{"question":"What are the alternatives to PIC18F04Q40-E/SL?","answer":"Microchip offers the PIC16LF1559-I/SS as a lower--bit alternative with 32 MHz max speed and 17 I/O, but it lacks the 125°C rating (only 85°C) and the DACs. For a 16-bit step up, the PIC24FJ256GA106-I/MR provides 256 KB Flash and 53 I/O at 32 MHz in a different package.
