Product details

It integrates an ECANbus controller (CAN 2.0B), along with I2C, SPI, LINbus, and two UART/USART modules — a peripheral set that targets distributed control nodes in industrial automation, building management, and automotive body electronics (non-safety). With 35 I/O lines and an 11-channel 12-bit ADC, it can handle a mix of digital sensors, relay drivers, and analog feedback in a single package.

Industrial temperature and 44-QFN — board-level fit

The 44-QFN package (8x8 mm) with an exposed pad needs a good thermal via stitch under the pad if the MCU drives more than a few hundred milliamps through its I/O pins — the die's junction-to-ambient thermal resistance benefits from a copper pour on the bottom layer.

The part is ROHS3 compliant.

Frequently asked questions

How many I/O pins does PIC18F46K80-I/ML have?

It provides 35 general-purpose I/O pins in the 44-QFN package. Eleven of those can be configured as analog inputs through the 12-bit ADC.

Is PIC18F46K80-I/ML RoHS compliant?

Yes, it is listed as ROHS3 compliant.

What is the maximum clock speed of PIC18F46K80-I/ML?

The core runs at 64 MHz maximum, using the internal oscillator or an external clock source.

Is PIC18F46K80-I/ML 5V tolerant?

Yes — the supply range goes up to 5.5 V, so it is fully 5 V tolerant. The I/O pins are rated for the same Vdd range, so 5 V logic levels are fine as long as Vdd is at or above 4.5 V.

Can I use PIC18F46K80-I/ML as a replacement for PIC18F46K22?

The PIC18F46K80 adds an ECANbus controller and runs at 64 MHz versus the K22's 48 MHz, with the same 64 KB Flash and 44-QFN footprint. Pin compatibility depends on the specific peripheral mapping — the CAN module occupies different pins. Check the respective datasheets for port assignments before dropping it into a K22 layout.
