PIC18F8622-E/PT - 8-Bit 25MHz MCU 64KB Flash 80-TQFP | Microchip
MPN： PIC18F8622-E/PT ✓ 啟用中PIC18F8622-E/PT 概覽
The PIC18 family belongs to the 8-bit microcontroller hierarchy that includes microcontroller unit (MCU) -> embedded controller -> microprocessor -> semiconductor. Within this hierarchy, PIC18FX522 parts are high-pin-count variants optimized for human-machine interface (HMI), motor control, and bridging applications. PIC18F8622 specifically is the 80-pin member of the PIC18F8722 family, sharing the same peripheral set across smaller-pin variants.
Key features include a 10-bit ADC with up to 16 channels, 4 enhanced CCP/ECCP modules, a parallel slave port for external memory-style bus expansion, and the PIC18 nanoWatt power management suite. The architecture is built around an enhanced Harvard RISC core with a hardware multiplier, single-cycle 200 ns instruction execution, and on-chip ICD (in-circuit debugger) support.
Typical applications include industrial automation controllers, automotive body/comfort modules, large-format graphical LCD control, sensor hub aggregation nodes, and embedded connectivity gateways. The high I/O count (70 user I/Os) is particularly useful when many digital control lines must be addressed without external bus expanders.
When designing, note that the '-E' suffix denotes the extended (-40C to +125C) industrial operating temperature range; the PIC18F8622 variant (no suffix) is the 0C to +70C commercial grade. Code written for PIC18F8722 (128 KB) can typically be ported down to PIC18F8622 (64 KB) by trimming data tables and lookup arrays. The PIC18F8622 is recommended for automotive design by Microchip; special ordering codes apply for full AEC-Q100 grades.

典型應用
PIC18F8622-E/PT 適用於 6 應用s: Industrial Automation Controller, Automotive Body and Comfort Module, Graphical LCD and HMI Controller, Sensor Hub Aggregation Node, Embedded Connectivity Gateway, Motor Control and PWM Driver Board.
Industrial Automation Controller
The PIC18F8622-E/PT's 70 I/O pins and four serial ports (2x I2C/SPI + 2x USART) make it well-suited for industrial PLC and distributed I/O modules that must aggregate dozens of digital inputs, drive relay or MOSFET outputs, and bridge to upstream HMIs. Its 64 KB Flash fits typical ladder-logic translation firmware plus diagnostic libraries, while the extended -40C to +125C temperature rating supports factory-floor cabinet environments. The PIC18 nanoWatt idle modes (down to nanoamp-level sleep current) enable always-on sensor nodes that wake on interrupt, reducing panel power consumption by orders of magnitude compared with always-active designs.
推薦
Automotive Body and Comfort Module
Microchip specifically recommends the PIC18F8622 family for automotive body-comfort designs such as seat controllers, mirror adjusters, and HVAC blend-door actuators. The PIC18F8622-E/PT's -40C to +125C industrial range covers cabin and underhood-adjacent environments, while the LIN-capable USART enables single-wire LIN bus connectivity that is standard in automotive body networks. The hardware multiplier and ECCP modules simplify PWM-driven motor control for small DC and stepper loads. Note that full AEC-Q100 qualification requires the dedicated automotive ordering codes referenced on the Microchip product page.
推薦
Graphical LCD and HMI Controller
The PIC18F8622-E/PT's parallel slave port and abundant I/O (70 pins) make it a strong host for medium-resolution graphical LCDs and TFT panels in industrial HMIs. The 4 KB RAM accommodates display frame buffers for monochrome graphics up to 128x64 pixels or small color UIs, while the 64 KB Flash stores font tables, menu structures, and bitmaps. Four CCP/ECCP modules can simultaneously drive backlight PWM, touchscreen scanning, and status LEDs. Designers can migrate upward to the PIC18F8722 (128 KB Flash) in the same 80-TQFP footprint if the UI asset set grows beyond 64 KB.
推薦
Sensor Hub Aggregation Node
With 16 ADC channels and two I2C/SPI ports, the PIC18F8622-E/PT can aggregate multiple analog and digital sensors into a single upstream reporting node. Typical deployments include HVAC sensor arrays (temperature, humidity, CO2, particulate), process-control manifolds, or building-automation rack nodes. The PIC18 nanoWatt sleep modes drop the MCU to nanoamp currents between sample intervals, enabling battery-backed or energy-harvested sensor pods. The 4 KB RAM buffer holds enough samples for short-term averaging before forwarding over the LIN-capable USART to a central controller.
推薦
Embedded Connectivity Gateway
The PIC18F8622-E/PT's four serial ports (2x I2C/SPI + 2x USART, LIN-capable) and parallel slave port make it well-suited as a protocol-translation gateway between legacy RS-232/RS-485 industrial buses, SPI peripherals, and LIN sub-networks. Its 64 KB Flash fits compact protocol stacks for Modbus RTU, LIN 2.x, and I2C sensor bridging, while the ECCP modules can generate timing-critical waveforms. Industrial temperature rating supports cabinet installations, and the same 80-TQFP footprint across the PIC18F8622/PIC18F8722 family allows firmware upgrades to add richer protocol libraries without PCB rework.
推薦
Motor Control and PWM Driver Board
The PIC18F8622-E/PT's four enhanced CCP/ECCP modules deliver up to four independent PWM channels, sufficient for small BLDC, stepper, or multi-phase DC motor control on a single MCU. The hardware 8x8 multiplier accelerates Park/Clarke transformations used in simple FOC algorithms, while 16 ADC channels sample current-sense amplifiers and back-EMF comparators in real time. The 70 I/O lines accept quadrature encoder inputs, limit switches, and fault signals without external bus expanders. The -E temperature grade supports motor enclosures where ambient temperatures routinely exceed 85C.

主要差異化特點
- Maximum Flash capacity at the lowest cost in the 80-pin family (對比PIC18F8722-E/PT)
- Full ADC + 4 CCP/ECCP modules vs stripped peripheral set (對比PIC18F8620-E/PT)
- Higher I/O count and Flash than 40-pin siblings (對比PIC18F4620-E/PT)
設計說明
The PIC18F8622-E/PT requires a 4.2 V to 5.5 V supply; if your system runs from 3.3 V only, choose the PIC18LF8622-I/PT (drop-in pin compatible) or add a boost regulator. Place 100 nF decoupling on every VDD/VSS pair (the package has multiple VDD/VSS pins: 11/10, 21/20, 31/30, 41/40, 51/50, 61/60, 71/70) plus a 10 uF bulk cap on the main VDD rail. AVSS (pin 80) must be tied to VSS even when the ADC is unused, with its own dedicated ground return to the analog reference if used.
Route the 25 MHz crystal traces (OSC1/OSC2, pins 1-2) with short, symmetric traces and guard ground on both sides; keep them away from the parallel slave port (RD0-RD7, RE0-RE2) which carries bus switching noise. Place MCLR (pin 3) pull-up close to the pin per Microchip ICD specifications. The PGC/PGD pins (RB6/RB7, pins 18-19) must be accessible for in-circuit debugging - do not place series resistors over 470 ohm on these lines or ICD programming will fail.
Watch for the suffix distinction: PIC18F8622 (commercial 0-70C), PIC18F8622-I (industrial -40 to +85C), and PIC18F8622-E (extended -40 to +125C) all exist in the same 80-TQFP. Choosing the wrong grade for an industrial cabinet design causes field failures. Automotive designs must use the dedicated AEC-Q100 ordering codes, not the -E industrial grade, despite the overlapping temperature range.
合規資訊
Microchip recommends PIC18F8622 family for automotive design, but the -E industrial variant is not itself AEC-Q100 qualified; full Q100 grades require special automotive ordering codes. RoHS and lead-free status confirmed per Microchip product page.
