Product details

40 MHz 8-bit PIC with CAN — what it covers

The Microchip PIC18LF2680-I/SO is an 8-bit MCU from the PIC® 18F family, clocked at 40 MHz with 64 KB of Flash program memory, 3.25 KB of RAM, and 1 KB of EEPROM. 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.

Frequently asked questions

Does PIC18LF2680-I/SO have a CAN bus interface?

Yes, it includes a CAN 2.0 controller. The module handles the protocol layer; an external CAN transceiver (such as an MCP2551) is needed for the physical bus.

What is the difference between PIC18LF2680 and PIC18F2680?

The LF suffix indicates the low-voltage range (2 V to 5.5 V) versus the standard F version (4.2 V to 5.5 V). The LF variant is the one to pick for 3.3 V or battery-powered designs; the F version is limited to 5 V nominal rails.
