PIC18F6585-E/PT 개요
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and a range of peripherals onto one silicon die. The PIC18 family represents Microchip's high-performance 8-bit architecture, sitting above the baseline PIC10/12/16 families and offering more memory, more peripherals, and C-compiler-friendly instruction set extensions. Within Microchip's product tree, PIC18F parts are categorized as 8-bit microcontrollers -> microcontrollers -> integrated circuits -> semiconductors.
Key features include 54 digital I/O pins, two 8-bit timers and three 16-bit timers, two enhanced CCP modules, a 12-bit 8-channel ADC, an ECAN module for automotive and industrial networking, two USART ports, an SPI bus, an I2C bus, 1 KB of data EEPROM, and an internal 8 MHz RC oscillator. The 25 MHz operating frequency combined with the 16-bit-wide instruction path yields up to 10 MIPS throughput, and the 16-bit flash cell architecture allows read-while-write self-programmability for field firmware upgrades.
Architecturally, the device uses a Harvard-based RISC core with a 32-level hardware stack, an 8x8 hardware multiplier in a single cycle, and a flexible interrupt controller supporting prioritized vectored interrupts. The ECAN peripheral implements the full CAN 2.0B active specification with 8 message buffers and hardware acceptance filters, while the 12-bit ADC delivers up to 100 ksps conversion with acquisition time configurable per channel.
Typical applications include automotive body and chassis controllers, industrial CAN-bus nodes, sensor aggregation hubs, HVAC control modules, and consumer appliances requiring field-upgradeable firmware. The wide operating voltage and extended temperature range make it suitable for harsh-environment designs, while the ECAN module simplifies node addition to existing automotive or industrial CAN networks.
When designing with this part, ensure decoupling capacitors are placed within 5 mm of each power pin and that unused I/O pins are configured as outputs to minimize quiescent current draw. The ICD/ICSP pins must be brought out to a header for in-circuit debugging during development.

설계 노트
Place 100 nF decoupling capacitors within 5 mm of each VDD pin (pins 11, 21, 31, 41, 51, 61) and a single 10 uF bulk capacitor near the supply entry point. The device has six VDD/VSS pairs distributed across the die; missing decoupling on any pair can cause logic errors during CAN bus transitions. For automotive applications subject to load-dump transients, add a TVS diode (e.g., SMAJ5.0CA) and series inductor on the VDD supply rail. A 100 kohm pull-up on MCLR is mandatory for proper reset behavior.
The PIC18F6585-E/PT in TQFP-64 has a junction-to-ambient thermal resistance (theta_JA) of approximately 45 C/W. At maximum operating temperature of 125 C ambient, the device dissipates up to 1 W continuously without thermal relief. For sealed enclosures with no airflow, derate CPU activity to keep junction temperature below 150 C. The -E grade part is qualified for automotive under-hood environments where ambient temperatures can reach 125 C during engine operation.
Route the crystal oscillator traces (RA6/OSC2 and RA7/OSC1, pins 8-9) as short and symmetric as possible, with guard traces to ground on both sides. Keep these traces away from the ECAN bus signals (RC6/CANTX and RC7/CANRX, pins 28-29) to minimize coupling. The ICSP pins (RB6/PGC and RB7/PGD, pins 18-19) must be brought out to a 6-pin header for in-circuit debugging and field firmware updates. Use a ground plane on the top layer beneath the MCU with stitching vias around the perimeter.
Configuration bits must be set correctly during programming - in particular the WDT, BOR, and oscillator selection bits. Failure to disable the watchdog timer in software can cause unexpected resets. Unused I/O pins should be configured as outputs and driven low to minimize quiescent current draw. The 5 V supply tolerance of 4.2-5.5 V means that designs powered from USB VBUS (5.25 V max) require additional headroom consideration. ECAN bit timing must be calculated per CiA recommendations for the chosen bus baud rate.
For reliable ECAN communication at 1 Mbps, add a 120 ohm termination resistor at each end of the CAN bus and use twisted-pair cabling. The CANTX and CANRX traces (pins 28-29) should be routed as a differential pair with characteristic impedance of 120 ohms. Keep CAN traces away from switching power converters and high-current traces. The MCP2551 transceiver requires a 5 V supply and provides the physical layer interface between the MCU's logic-level ECAN and the differential bus.
