PIC18F8585-E/PT 概要

The Microchip Technology PIC18F8585-E/PT is an 8-bit PIC18F-family CMOS flash microcontroller running at up to 25 MHz (E suffix denotes the Extended industrial temperature grade, -40C to +125C), integrating 48 KB of program Flash organized as 24K x 16 words, 3,328 bytes of RAM, and 1,024 bytes of data EEPROM, all in an 80-pin TQFP (12x12 mm) package. The 'E' in the part number denotes the Extended temperature range, and '/PT' is the 80-lead TQFP packaging designator.

An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path and Harvard architecture, integrating CPU core, program memory (Flash/ROM), data memory (RAM), non-volatile EEPROM, and a rich set of peripherals including timers, communication interfaces (UART, SPI, I2C), and analog-to-digital converters. PIC18F-series microcontrollers specifically sit in the hierarchy 8-bit MCU -> PIC micro -> microcontroller -> embedded computing -> semiconductor, and use Microchip's enhanced instruction set to deliver up to 10 MIPS at 40 MHz with 16-bit-wide instructions and single-cycle multiply.

Key features of the PIC18F8585-E/PT include a 12-channel 10-bit Analog-to-Digital Converter (ADC) with input multiplexing across up to 68 I/O pins, two Capture/Compare/PWM (CCP) modules plus an Enhanced CCP (ECCP), two USART modules with LIN support, an MSSP port configurable as SPI or I2C (master/slave), a CAN 2.0B module, four 8-bit timers and three 16-bit timers/watchdogs, two analog comparators, and a 16-bit Parallel Slave Port. It supports in-circuit serial programming (ICSP) and in-circuit debug (ICD) via two pins, and operates from 4.2 V to 5.5 V with industrial-grade ESD and latch-up performance.

Architecturally, the device uses an enhanced RISC core with 32-level hardware stack, 8x8 hardware multiplier, and a 16-bit instruction word optimized for deterministic interrupt response and C-compiler code density. The 80-pin TQFP exposes 68 digital I/O lines plus dedicated oscillator, programming, and analog reference pins. Power-managed modes include Run, Idle, and Sleep with multiple wake-up sources, enabling battery-friendly operation.

Typical applications include industrial control with CAN networking, automotive body and chassis ECUs, HVAC and building automation, motor control (BLDC and stepper), instrumentation front-ends, and any embedded design requiring abundant I/O plus on-chip CAN, ADC, and PWM peripherals. Compared with switching regulator solutions, the on-chip ADC and analog comparators avoid external analog front-end ICs in many designs.

When designing with the PIC18F8585-E/PT, use the MPLAB X IDE with the free XC8 compiler and MPLAB Code Configurator (MCC) for peripheral setup. Reserve dedicated pins for MCLR, OSC1/OSC2, AVSS/AVDD, and ensure decoupling capacitors are placed close to the supply pins. The '-E' temperature grade qualifies the part for -40C to +125C operation, distinguishing it from the standard 'I' grade.

This page synthesizes distributor stock and lead-time intelligence, drop-in and pin-compatible alternatives within the same 80-TQFP footprint, and engineering design notes that complement the manufacturer's datasheet to accelerate BOM selection and PCB redesign.

主な用途

PIC18F8585-E/PT の用途: 6 件s: Industrial Control with CAN Networking, Automotive Body and Chassis ECU, HVAC and Building Automation, Motor Control (BLDC and Stepper), Instrumentation and Data Acquisition Front-End, Display and User-Interface Controllers.

🏭

Industrial Control with CAN Networking

The PIC18F8585-E/PT is purpose-built for industrial control nodes on a CAN 2.0B bus because it integrates a hardware CAN module plus 68 digital I/O, 3,328 bytes RAM, and a 10-bit ADC in a single 80-TQFP package. Placed on a sensor/actuator node, the CAN peripheral handles bus arbitration at up to 1 Mbps while the ADC samples analog inputs at 10 ksps and CCP/ECCP modules drive triac or PWM outputs. The -40 C to +125 C Extended temperature grade lets the same firmware deploy in cabinet, factory-floor, and outdoor enclosures without BOM changes.

🚗

Automotive Body and Chassis ECU

In automotive body controllers, the PIC18F8585-E/PT's 48 KB Flash and 3,328 bytes RAM comfortably hold a CAN stack plus LIN master/slave USART logic, while the Extended temperature grade survives underhood and cabin thermal extremes. Its 10 MIPS at 25 MHz compute headroom is sufficient for body-controller scheduling, debounced switch inputs via parallel slave port, and PWM-driven lighting actuators. The integrated 16-bit PSP lets a host processor offload low-latency I/O without burdening the main MCU.

🏭

HVAC and Building Automation

HVAC controllers benefit from the PIC18F8585-E/PT's combination of analog comparators for thermistor sensing, a 10-bit ADC with up to 12 channels for multi-zone temperature sampling, and ECCP PWM outputs for triac-fired heater and damper actuators. The 3,328 bytes RAM and 1,024 bytes EEPROM store scheduling tables and learned comfort profiles across power cycles. The Extended -40 C to +125 C grade covers rooftop and basement installations without derating the part selection.

⚡

Motor Control (BLDC and Stepper)

Stepper and BLDC motor control loops are well-served by the PIC18F8585-E/PT's two CCP plus one Enhanced CCP module generating complementary PWM with programmable dead time, plus 3,328 bytes RAM for state-machine controllers. The 25 MIPS throughput implements field-oriented control (FOC) software at moderate RPMs, while the 12-channel ADC simultaneously samples phase currents and back-EMF. Industrial-grade thermal headroom keeps the controller inside its junction limits inside sealed motor housings.

🔧

Instrumentation and Data Acquisition Front-End

Portable instrumentation leverages the PIC18F8585-E/PT's 10-bit ADC, 3,328 bytes RAM for sample buffers, and USART/SPI channels for tethered PC links or local display drivers. ICSP/ICD debugging lets firmware engineers iterate on calibration coefficients stored in the 1,024-byte EEPROM without removing the device from the board. The -40 C to +125 C grade supports outdoor test equipment, lab gear, and field-deployable measurement nodes.

📺

Display and User-Interface Controllers

User-interface controllers for industrial HMIs pair the PIC18F8585-E/PT's 68 I/O pins with character or graphic LCDs, keypads, and indicator LEDs, all driven directly without external logic. The 16-bit Parallel Slave Port offloads scanning from a higher-end host MCU when used as a co-processor, while the USART channels drive RS-232/RS-485 to upstream PLCs. The Extended temperature grade supports outdoor kiosks, vehicle dashboards, and freezer-cooler displays.

What is the program memory size of PIC18F8585-E/PT?
The PIC18F8585-E/PT integrates 48 KB of on-chip program Flash, organized as 24K x 16 words to match the 16-bit PIC18 instruction width. According to the Microchip PIC18F6585/8585/6680/8680 family datasheet, the program memory is rated for a minimum 100K erase/write cycles typical and supports in-circuit serial programming (ICSP) and runtime self-programming under firmware control.
How much RAM and EEPROM does PIC18F8585-E/PT have?
The PIC18F8585-E/PT provides 3,328 bytes of general-purpose SRAM distributed across multiple banks plus 1,024 bytes of data EEPROM for non-volatile parameter storage. Both figures are extracted from the Microchip PIC18F8585 family datasheet (Document 39646). The EEPROM block is rated for 1M erase/write cycles typical and is byte-erasable, simplifying calibration data and user-setting storage.
What is the maximum operating temperature of PIC18F8585-E/PT?
The PIC18F8585-E/PT operates over the Extended temperature range of -40 C to +125 C, designated by the 'E' suffix in the ordering code. This is distinct from the 'I' (Industrial, -40 C to +85 C) variant of the same die. For automotive or under-hood environments, the 'E' grade is typically required; for commercial-grade enclosures, the lower-cost 'I' part is usually acceptable.
What package does PIC18F8585-E/PT use?
The PIC18F8585-E/PT ships in an 80-pin Thin Quad Flat Pack (TQFP) measuring 12 x 12 mm with a 1.0 mm body height and 0.5 mm lead pitch. Per the Microchip package designation scheme, '/PT' specifically identifies the TQFP-80 package and tray packing. The 80-pin footprint exposes 68 general-purpose I/O plus dedicated oscillator, programming/debug, and analog reference pins.
Where can I buy PIC18F8585-E/PT and what is the price?
As of 2026-09-28, the PIC18F8585-E/PT is listed in stock at DigiKey (SKU 572875), Mouser, LCSC Electronics, and Heisener at distributor-pricing tiers of roughly $16.60 at qty-1, $14.85 at qty-10, $12.40 at qty-100, $10.95 at qty-500, and $9.55 at qty-1000 per the Verified Web Data. The Microchip product page also lists a Not Recommended for new Designs (NRND) lifecycle status, so consider pin-compatible successors for new designs.
What is the lead time for PIC18F8585-E/PT orders?
As of 2026-09-28, Heisener reports approximately 7,424 pieces in distributor stock with an estimated delivery window of 2026-11-27 to 2026-12-02 for standard shipping, while DigiKey advertises 'ships today' on listed qty-1 orders. Because Microchip marks the part NRND, distributors may reduce inventory over time; verify stock and lead time at order entry, particularly for production volumes.
PIC18F8585-E/PT vs PIC18F8585-I/PT - what is the difference?
The PIC18F8585-E/PT is the Extended temperature grade (-40 C to +125 C) running up to 25 MHz, while the PIC18F8585-I/PT is the Industrial grade (-40 C to +85 C) running up to 40 MHz. Both share the same 80-TQFP footprint, 48 KB Flash, 3,328 bytes RAM, and 1,024 bytes EEPROM, so they are pin-for-pin compatible at 25 MHz operation. Choose 'E' for harsh-environment or automotive under-hood designs and 'I' when 40 MHz throughput is required at standard industrial temperatures.
Can PIC18F8585-I/PT replace PIC18F8585-E/PT as a drop-in?
Yes, the PIC18F8585-I/PT is drop-in pin-compatible with the PIC18F8585-E/PT when the design is limited to -40 C to +85 C operation. Per the family datasheet both parts share the same 80-pin TQFP (12x12 mm) pinout and identical peripheral set, RAM, Flash, and EEPROM. Replacing 'E' with 'I' in cooler environments gains access to 40 MHz operation; the reverse 'I' to 'E' substitution is NOT drop-in if the design exceeds 85 C.
When should I choose PIC18F8585-E/PT over PIC18F8525?
Choose the PIC18F8585-E/PT when the design needs the Extended temperature grade (-40 C to +125 C), the on-chip CAN 2.0B module, and 48 KB of Flash plus 3,328 bytes RAM, in an 80-pin TQFP. The PIC18F8525-I/PT is a related 80-TQFP part in the same family but lacks the integrated CAN module. For new CAN-enabled industrial designs above 85 C, the PIC18F8585-E/PT remains the correct choice despite its NRND status; for new designs below 85 C consider the PIC18F67K90-I/PT or PIC18F66K80-I/PT instead.
What is the best cross-brand equivalent for PIC18F8585-E/PT?
There is no fully pin-compatible third-party equivalent to the PIC18F8585-E/PT because Microchip's PIC18F architecture, instruction set, and development toolchain are proprietary. Cross-brand alternatives require significant firmware porting; Atmel/Microchip ATmega1280 or NXP MC9S12E128 can substitute at the architectural level but use different cores, peripherals, and pinouts. For drop-in replacement within Microchip's portfolio, the PIC18F8585-I/PT and PIC18F6585-E/PT are the only true pin-to-pin equivalents.

Choose the PIC18F8585-E/PT when the design needs the Extended -40 C to +125 C temperature grade, on-chip CAN 2.0B, and 48 KB Flash plus 3,328 bytes RAM in the 80-TQFP (12x12 mm) footprint. Use the PIC18F8585-I/PT instead when industrial -40 C to +85 C is acceptable and 40 MHz operation would be beneficial. For designs without CAN, the PIC18F8525T-I/PT (or PIC18F8520-I/PT) drops the CAN block for cost savings while keeping the 80-TQFP layout. Avoid the PIC18F6585-E/PT unless 32 KB Flash is acceptable. For new designs, the PIC18F8585 is NRND - prefer PIC18F67K90-I/PT (64 KB Flash, 64-pin TQFP, XLP low-power) when possible despite the smaller package requiring PCB rework.

  • Larger 3,328 bytes SRAM vs sibling 80-TQFP parts (vs PIC18F6585-E/PT)
  • Extended temperature grade with same peripherals as the Industrial 'I' variant (vs PIC18F8585-I/PT)

設計ノート

Place a 100 nF decoupling capacitor within 5 mm of every VDD/VSS pair, plus a bulk 10 uF tantalum or ceramic on the main 5 V rail. The PIC18F8585-E/PT supports four supply pins (pin 18, 40, 59, plus AVDD); each must have its own local bypass. The analog supply AVDD should be filtered with a ferrite bead from VDD and bypassed with 100 nF plus 10 uF to AVSS to keep ADC noise below 1 LSB at 10-bit resolution.

Do not leave MCLR floating - the PIC18F8585-E/PT requires MCLR tied to VDD through a 10 kohm pull-up for normal operation, with a 100 nF cap to ground for noise immunity in electrically noisy industrial environments. ICSP clock (PGC, pin 38) and data (PGD, pin 39) share PORTB bit 6/7; ensure your application firmware releases these pins (TRISB bit set) before the programmer is connected or in-circuit debug will fail intermittently.

Estimated: at maximum clock (25 MHz) and full I/O toggling, the PIC18F8585-E/PT draws roughly 50 mA, dissipating 275 mW at 5.5 V VDD. With the TQFP-80 package theta_JA of approximately 45 C/W on a 4-layer JEDEC test board, the junction rises about 12 C above ambient. The Extended -40 C to +125 C grade accommodates up to 113 C ambient in worst-case sealed enclosures without active cooling.

Route the 25 MHz crystal traces (OSC1/OSC2, pins 7 and 8) as short as possible (under 10 mm) and surround them with a ground guard ring; keep these traces away from switching signals such as PWM outputs and CAN bus edges. The CANRX and CANTX pins (62 and 63 per datasheet) should route as a 100 ohm differential pair to the MCP2551 or similar CAN transceiver, with the bus termination 120 ohm resistors only at the cable ends.

When using the 16-bit Parallel Slave Port (PORTD plus PORTE bits 0-2), dedicate a contiguous 16-bit data bus plus three control lines (RD, WR, CS) and route them with matched lengths within 5 mm to avoid setup/hold violations on the host side. Reserve digital I/O on PORTF as the analog inputs so the analog mux lines stay short to AVSS/AVDD, minimizing ADC crosstalk during multi-channel sampling.
