PIC18C658-E/L 개요
What is a PIC18 microcontroller? The PIC18 family is a class of 8-bit Harvard-architecture microcontrollers from Microchip Technology, sitting hierarchically between the legacy PIC16 mid-range family and the 16-bit dsPIC/PIC24 families. PIC18 parts add a wider 16-bit instruction path, hardware multiplier, larger linear addressing space and richer peripherals while preserving the PIC16 programming model, making them the entry point for engineers needing CAN, USB, or larger memory footprints without moving to a 16-bit core.
Key features include 40 MHz maximum operating frequency (10 MIPS), 12-channel 10-bit ADC, integrated CAN 2.0B peripheral, 52 digital I/O pins, PWM, watchdog timer, brown-out reset, low-voltage detect and power-on reset. The 'E' suffix denotes the -40C to +125C extended temperature grade suited to industrial and automotive under-hood environments. The 68-pin PLCC (J-Lead) package gives through-hole solderability and reliable socketed programming on legacy boards.
The PIC18C658 is built on a baseline CMOS process and the architecture has been superseded by the flash-based PIC18F458 and PIC18F6585 families. Microchip's product page explicitly recommends the PIC18F6585 as the newer replacement. The OTP program memory cannot be re-programmed in-circuit, which is a key lifetime constraint for production designs.
Typical applications include CAN-based industrial node controllers, automotive body and chassis ECUs, building-automation gateways, and legacy factory-floor PLC I/O modules. The combination of CAN peripheral, extended temperature range and 52 I/O pins covers typical CAN node requirements without external bus controllers.
When designing with this part, note that OTP memory prevents firmware updates and the device is in Microchip's mature/legacy lifecycle; new designs should evaluate the PIC18F458, PIC18F6585 or dsPIC33E families. Use MPLAB IDE with MPASM or C18 compiler toolchain for firmware development.

일반적인 애플리케이션
PIC18C658-E/L 적합 용도: 6 애플리케이션s: Automotive CAN Body Controllers, Industrial CAN Node Modules, Building Automation Gateways, Legacy PLC I/O Modules, HVAC Control Boards, Sensor Hub / Data Acquisition Front-End.
Automotive CAN Body Controllers
The PIC18C658-E/L fits automotive CAN body controllers because of its integrated CAN 2.0B peripheral, 52 digital I/O pins for switch/relay scanning, and extended -40C to +125C temperature grade. The 32KB OTP program memory is sufficient for body-controller state machines that drive door locks, mirrors, lighting and HVAC actuators. Used between the CAN bus transceiver (e.g., MCP2551) and the load drivers, the MCU runs at 40 MHz / 10 MIPS to handle CAN message filtering, debouncing, and PWM dimming in real time. Trade-off: OTP memory prevents field firmware updates, so consider PIC18F6585 for designs that need post-production firmware revisions.
추천
Industrial CAN Node Modules
For factory-floor CANopen/DeviceNet slave nodes, the PIC18C658-E/L offers 32KB OTP for protocol stacks, 12-channel 10-bit ADC for sensor inputs, and 52 I/O for valve/sensor interfacing. The extended temperature grade supports unconditioned cabinet locations. Placed on a PLCC-68 socketed carrier, the part is easy to swap during commissioning. The on-chip CAN controller plus an external CAN transceiver eliminates the need for a separate bus controller IC. Limit: OTP memory blocks firmware updates, so choose PIC18F6585 for nodes that may need protocol-stack revisions.
추천
Building Automation Gateways
Building automation gateways that bridge RS-485, sensor networks, and CAN bus benefit from the PIC18C658-E/L's combination of 52 I/O, 12-bit ADC and CAN peripheral in a single package. The 32KB OTP accommodates BACnet or proprietary protocol stacks. Operated at 5V, the device interfaces directly with legacy 5V industrial sensors and actuators without level shifters. The PLCC-68 package supports socketed installation on DIN-rail carriers for field serviceability. For new gateway designs the flash-based PIC18F6680-I/L offers the same pinout with field upgradability.
추천
Legacy PLC I/O Modules
Legacy PLC I/O expansion modules often use the PIC18C658-E/L because of its PLCC-68 socketed form factor and 5V operation matching older PLC backplanes. The 52 I/O lines and 12-channel ADC cover typical analog/digital signal-conditioning I/O counts. Brown-out reset and watchdog timer provide deterministic recovery from industrial noise events. PLCC sockets allow hot-swap of modules during commissioning. Drawback: OTP memory means each variant needs its own masked part; flash-based PIC18F alternatives are recommended for any new PLC product line.
추천
HVAC Control Boards
The PIC18C658-E/L's 12-bit ADC for temperature/pressure sensors, PWM outputs for fan/blower speed control, and CAN interface for chiller/boiler networking make it well-suited to HVAC control boards. Extended -40C to +125C temperature range supports attic and rooftop installations. 32KB OTP holds the control algorithm and scheduler tables. The 40 MHz core computes PID loops in real time. Migration target: PIC18F6585 in the same PLCC-68 package for designs that need firmware-tuning capability.
추천
Sensor Hub / Data Acquisition Front-End
As a sensor hub front-end, the PIC18C658-E/L aggregates up to 12 analog sensor channels (10-bit ADC), multiplexes digital I/O, and forwards the data over CAN to a master controller. The 1536-byte RAM buffers short bursts, and 52 I/O drives addressable sensor arrays. The 40 MHz / 10 MIPS core handles CAN arbitration without missing frames. PLCC-68 socketed design simplifies field replacement. For new sensor hubs requiring field firmware updates, the PIC18F6585-I/L is the recommended same-package drop-in.

주요 차별점

설계 노트
PIC18C658-E/L operates from a single 5V supply. Decouple each VDD/VSS pair with a 100nF ceramic capacitor placed within 5 mm of the pin; add a bulk 10uF tantalum or aluminum capacitor at the board supply input. The device has multiple VDD pins (10, 20, 30, 40, 66) - tie all to 5V and all VSS to ground. Brown-out reset (BOR) and low-voltage detect (LVD) provide brown-out protection; configure BOR in the configuration bits to match your application's minimum operating voltage (typically 4.2V).
PIC18C658-E/L program memory is OTP (One-Time Programmable), not flash - the firmware cannot be updated once programmed. Verify firmware correctness in a flash-based PIC18F equivalent (PIC18F6585 or PIC18F458) before committing to OTP programming. ICSP programming via PGC/PGD pins 27/28 requires MPLAB and a compatible programmer; ensure ICSP pins are accessible on the PCB and not used as outputs during programming (MCLR/VPP on pin 18 must be driven to programming voltage during programming).
Place the external CAN transceiver (e.g., MCP2551) within 50 mm of pins 24 (CANRX) and 25 (CANTX) to keep the bus stub short. Use a 120 ohm termination resistor at each end of the CAN bus and route CANH/CANL as a twisted pair with characteristic impedance of 120 ohms. The 40 MHz oscillator crystal on pins 8/9 should be placed close to the IC with short traces and a guard ground to minimize EMI; OSC1/OSC2 are sensitive to stray capacitance.
규정 준수 정보
RoHS/REACH/lead-free status not explicitly listed in the verified data. The 'E' extended temperature grade (-40C to +125C) makes the part suitable for industrial and many automotive applications, but AEC-Q100 qualification is not stated - contact Microchip for automotive qualification documentation before deploying in safety-critical automotive ECUs.
