What are the key features of PIC18F66K80-I/PT?
- Integrated ECAN (CAN 2.0B) controller enables direct connection to CAN bus networks in automotive and industrial designs
- 12-bit ADC with CTMU (Charge Time Measurement Unit) supports capacitive touch sensing alongside precision analog acquisition
- 64 MHz maximum clock speed with 8-bit PIC18 core delivers up to 16 MIPS for responsive real-time control tasks
- Operates down to 1.8 V at 4 MHz, enabling battery-powered or energy-constrained CAN node deployments
- 64-pin TQFP package provides ample I/O for complex control panels and multi-bus embedded systems
What is PIC18F66K80-I/PT used for?
PIC18F66K80-I/PT is well suited for automotive body control modules, industrial CAN node gateways, and HVAC controllers that require a direct CAN 2.0B interface alongside analog sensor acquisition and capacitive touch input. Its wide operating voltage range down to 1.8 V and 64 KB Flash budget also make it effective for energy-metering endpoints and motor control pre-driver boards that must log data, manage CAN messaging, and handle touchpad user interfaces from a single MCU.

Frequently Asked Questions
Does PIC18F66K80-I/PT include an on-chip CAN controller, and which CAN standard does it implement?
Yes, the device includes an ECAN module compliant with CAN 2.0B, supporting data rates up to 1 Mbps. This eliminates the need for an external MCP2515 CAN controller in automotive body-module or industrial fieldbus designs using the 64-pin TQFP package.
What ADC resolution does PIC18F66K80-I/PT provide, and can it measure capacitive touch inputs?
The device integrates a 12-bit ADC paired with the CTMU (Charge Time Measurement Unit), which enables capacitive touch sensing on the same ADC input pins used for voltage measurement. This dual capability lets designers add touch-button interfaces to CAN-connected control panels without external touch controllers.
At what minimum supply voltage can PIC18F66K80-I/PT operate, and what clock speed is available at that voltage?
PIC18F66K80-I/PT operates at a minimum supply of 1.8 V, achieving up to 4 MHz at that rail. Full-speed operation at 64 MHz is available from the nominal 3.3 V to 5 V supply range, making it flexible for both battery-powered remote sensors and 5 V industrial control boards.
