Applications
The PIC18F4682-I/PT is commonly used in automotive body-control modules, industrial motor drives, and building automation controllers where the on-chip CAN 2.0B peripheral allows direct connection to a CAN bus at up to 1 Mbps without an external transceiver IC. Its 80 KB Flash, 40 MHz core, and multi-channel 10-bit ADC also make it a capable platform for HVAC controllers, smart metering nodes, and robotics joint controllers that need deterministic real-time performance in a compact 44-pin TQFP footprint.

Frequently Asked Questions
Does the PIC18F4682-I/PT include a CAN controller, and at what bus speed does it operate?
Yes, the PIC18F4682-I/PT integrates a full CAN 2.0B active controller with 3 receive buffers and 3 transmit buffers, supporting CAN bus speeds up to 1 Mbps. This allows the chip to connect directly to automotive and industrial CAN networks using only an external CAN transceiver such as the MCP2551, without a separate controller IC.
What clock frequency and instruction throughput does the PIC18F4682-I/PT achieve?
The PIC18F4682-I/PT runs at up to 40 MHz from an external crystal or PLL-multiplied internal oscillator, executing most PIC18 instructions in a single cycle for a throughput of 10 MIPS. Its hardware 8x8 multiplier completes in 2 instruction cycles, which accelerates PID loops, FIR filter computation, and sensor-data scaling common in embedded control applications.
How many ADC channels are available on the PIC18F4682-I/PT, and what is its resolution?
The PIC18F4682-I/PT provides 13 analog input channels connected to a single 10-bit successive-approximation ADC with programmable acquisition time and a maximum conversion rate of approximately 100 ksps. This multi-channel front end supports simultaneous conditioning of temperature sensors, pressure transducers, and potentiometers in industrial or HVAC measurement systems without external multiplexers.
When is the PIC18F4682-I/PT a better choice than the smaller PIC18F2682 for a CAN-enabled design?
The PIC18F4682-I/PT uses a 44-pin TQFP package versus the 28-pin SPDIP or SOIC of the PIC18F2682, providing 36 digital I/O pins compared to 22. The extra 14 pins accommodate larger keypad matrices, status-LED arrays, or additional sensor inputs in automotive body-control or industrial node designs that the 28-pin variant cannot support, while sharing the same CAN 2.0B core, 80 KB Flash, and 40 MHz maximum speed.
