It integrates a CAN 2.0 controller, I²C, SPI, and two UART/USART serial interfaces, plus an 8-channel 10-bit ADC. ## Supply voltage and the LF variant The LF variant operates down to 2 V, suiting battery-powered or energy-harvesting edge nodes. For a storeroom or MRO buyer, this means the part is still in normal production and can be ordered against a BOM line without obsolescence risk. ## Peripherals and I/O budget With 25 I/O lines, the part can handle a keypad matrix, a small character LCD, and a few discrete sensors alongside the CAN transceiver interface.","metaTitle":"PIC18LF2680-I/SO 8-bit MCU, 40MHz, 64KB Flash, 28-SOIC","metaDescription":"Microchip PIC18LF2680-I/SO 8-bit MCU: 40MHz core, 64KB Flash, 3.25KB RAM, 1KB EEPROM, CAN 2.0, 2V-5.5V supply, -40°C to +85°C.
