The supply range runs from 1.8V to 3.6V, so it plays nicely with a single Li-ion cell or a regulated 3.3V rail. ## Peripheral set and memory — what fits on the die On the peripheral side you get 35 I/O lines, a 30-channel 10-bit ADC, and serial connectivity covering I²C, SPI, and UART/USART. ## 44-TQFP — rework and footprint notes The 0.8 mm pitch gives you a bit of breathing room under the hot-air station compared to finer-pitch QFPs — the pads are visible enough to align by eye if you have to hand-place a replacement.","metaTitle":"Microchip PIC18LF46K22-E/PT 8-bit MCU, 48 MHz, 64 KB Flash","metaDescription":"Microchip PIC18LF46K22-E/PT 8-bit PIC MCU, 48 MHz core, 64 KB Flash, 3.8 KB RAM, 1 KB EEPROM, 1.8V-3.6V, -40°C to 125°C, 44-TQFP.","metaKeywords":null},"attributes":{"series":"PIC® XLP™ 18K","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"48MHz","Series":"PIC® XLP™ 18K","Package":"Tray","RAM Size":"3.8K x 8","Core Size":"8-Bit","EEPROM Size":"1K x 8","Peripherals":"Brown-out Detect/Reset, HLVD, POR, PWM, WDT","Connectivity":"I²C, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"35","Core Processor":"PIC","Package / Case":"44-TQFP","Data Converters":"A/D 30x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"64KB (32K x 16)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"44-TQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.67","priceTiers":[{"qty":1,"price":"$4.67000","currency":"USD"},{"qty":25,"price":"$4.27800","currency":"USD"},{"qty":100,"price":"$3.88700","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/de4ff4324634540b7aeb20210c448d97.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/PIC18LF46K22-E%2FPT/alternatives.json"},"ai":{"faq":[{"question":"Can PIC18LF46K22-E/PT replace PIC18F46K22?","answer":"The PIC18LF46K22-E/PT is the low-voltage (1.8V to 3.6V) variant of the PIC18F46K22, which typically runs on a higher supply range. Pin-compatible in the same 44-TQFP package, but the 'LF' version is optimised for battery-powered XLP designs. Check the supply rail in your existing BOM — if it's 5V, the 'LF' won't work without a regulator."},{"question":"What is the program memory size of PIC18LF46K22-E/PT?","answer":"64 KB of Flash program memory, organised as 32K x 16 bits.
