Key Features
- Integrated CAN 2.0B controller with hardware message filtering enables direct connection to automotive and industrial CAN buses at up to 1 Mbps without an external CAN controller
- 32KB self-programmable Flash and 1.5KB EEPROM support firmware-over-the-air updates and persistent parameter storage in embedded control nodes
- 10-bit ADC with 8 input channels allows direct analog signal acquisition from temperature sensors, pressure transducers, and potentiometers at up to 40 MHz system clock
- Wide supply range down to 2V minimum extends usability in low-voltage and battery-backed control systems alongside 5V automotive ECU rails
Applications
The PIC18F458-I/PT is designed for automotive body control modules, industrial CAN network nodes, motor-drive controllers, and embedded systems that require an on-chip CAN 2.0B interface combined with the rich peripheral set of the PIC18 architecture. Its 44-pin TQFP form factor and 40 MHz throughput make it a cost-effective controller for CANopen and DeviceNet slave nodes in factory automation equipment, agricultural machinery, and HVAC control panels.

Frequently Asked Questions
Does the PIC18F458-I/PT include a hardware CAN controller, and which CAN specifications does it support?
Yes. The PIC18F458-I/PT integrates a hardware CAN 2.0B active controller supporting standard 11-bit and extended 29-bit frame identifiers at data rates up to 1 Mbps. The controller includes 3 transmit buffers and 2 receive buffers with hardware message filtering, reducing CPU interrupt overhead in multi-node CANopen or J1939 networks.
What is the Flash memory capacity of the PIC18F458-I/PT, and how does it compare to smaller PIC18 devices?
The PIC18F458-I/PT provides 32KB of self-programmable Flash program memory and 1.5KB of on-chip EEPROM, significantly more than entry-level PIC18 parts such as the PIC18F252 (32KB Flash but no CAN) or PIC18F248 (16KB Flash), making it the preferred choice when a CAN interface and larger firmware footprint are simultaneously required.
Which supply voltages does the PIC18F458-I/PT support, and how does this broaden its application range?
The device operates from 2V to 5.5V supply. At the 2V minimum it runs at reduced speed, while full 40 MHz operation is available from 4.2V to 5.5V, allowing use in 5V automotive ECU designs, 3.3V industrial sensor nodes, and 2-cell battery-powered control units within a single part number.
For a TQFP-44 layout, how many I/O pins does the PIC18F458-I/PT expose, and are they 5V tolerant?
The 44-pin TQFP package provides up to 33 configurable I/O pins, all of which are 5V tolerant when the device is powered from a 5V rail. This makes the PIC18F458-I/PT suitable for direct interfacing with 5V CAN transceivers, relay drivers, and industrial digital inputs without additional level-shifting components.
