Key Features
- 8-bit PIC18 core at up to 40 MHz with 48 KB Flash and 3328 bytes RAM supporting complex CAN protocol stacks and application firmware in a single chip
- Integrated Enhanced CAN (ECAN) controller enabling direct connection to automotive and industrial CAN bus networks without an external CAN controller IC
- On-chip ADC with multiple input channels in a 44-pin TQFP package providing analog sensor acquisition alongside CAN communications for compact ECU designs
Applications
The PIC18F4585-E/PT is tailored for CAN bus node implementations in automotive body control modules, industrial motor drives, and building automation controllers where 8-bit performance at 40 MHz suffices. Its integrated ECAN peripheral handles message filtering and buffering autonomously, freeing the CPU for application logic in multi-node CAN networks with up to 1 Mbit/s data rates. The 44-pin TQFP package supports full-featured designs with CAN, ADC, UART, SPI, and I2C peripherals on a single chip.

Frequently Asked Questions
What CAN bus data rate does the PIC18F4585-E/PT's ECAN controller support, and how does it reduce CPU load?
The integrated ECAN controller supports CAN bus data rates up to 1 Mbit/s and includes hardware message filtering and multi-buffer FIFO that receive and queue frames independently of the CPU. This hardware offload allows the 40 MHz PIC18 core to execute application logic without servicing every incoming CAN frame interrupt, reducing latency in time-critical control loops in automotive and industrial CAN node implementations.
How does 48 KB of Flash compare to smaller PIC18 variants for CAN gateway firmware complexity?
With 48 KB Flash the PIC18F4585-E/PT can hold a CAN gateway firmware image that includes a CANopen or J1939 protocol stack (typically 10-20 KB), application logic, and a bootloader in a single device without external memory. Smaller PIC18 variants with 16 KB or 32 KB Flash require either a stripped protocol stack or an external serial Flash, adding BOM cost and complexity to the gateway design.
For a compact automotive sensor node, how does the PIC18F4585-E/PT's ADC complement the ECAN peripheral?
The on-chip ADC allows the PIC18F4585-E/PT to digitize analog sensor signals — such as temperature (0-5 V NTC output), pressure (4-20 mA loop), or accelerometer voltage — and transmit the converted values over the CAN bus, all within a single-chip solution at 40 MHz. This eliminates the need for a separate ADC IC and its SPI bus, reducing the node PCB to the MCU, a CAN transceiver, and passive components in a 44-pin TQFP footprint.
What extended temperature range does the PIC18F4585-E/PT support, making it suitable for automotive engine bay deployments?
The -E suffix on PIC18F4585-E/PT denotes the extended temperature grade, rated from -40°C to +125°C operating range. This range covers automotive under-hood environments where ambient temperatures can exceed 85°C in summer conditions, ensuring reliable ECAN communication and ADC accuracy throughout the full thermal envelope without component derating or the need for thermal management measures in most ECU enclosure designs.
