PIC18F8627-E/PT - 96KB Flash 8-bit MCU 80-Pin TQFP | Microchip
MPN： PIC18F8627-E/PT ✓ 啟用中PIC18F8627-E/PT 概覽
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (program flash + SRAM), non-volatile EEPROM, and configurable peripherals onto one silicon die. The 8-bit data path executes arithmetic and logic on bytes, and modern enhanced 8-bit cores such as the PIC18 family add a 16-bit instruction word and hardware multiply to deliver near-16-bit performance for control-loop, sensor-interface, and human-machine-interface applications. Within the broader taxonomy, the PIC18F8627 belongs to the 8-bit MCU category, which sits under microcontroller -> microprocessor -> semiconductor device.
This part is the extended-temperature ("-E") variant rated for -40 C to +125 C operation, making it suitable for industrial and harsh-environment deployments. Compared with the PIC18F8525/8622 predecessors, the PIC18F8627 doubles the flash to 96 KB and adds the enhanced CAN peripheral plus USB-ready oscillator blocks. The 80-pin TQFP exposes four 8-bit ports plus extra analog and timer pins, enabling direct drive of graphical LCDs, keypads, and motor-driver stages.
Typical applications include industrial control panels, automotive body and HVAC modules, building-automation gateways, medical instrument controllers, and consumer appliances requiring graphical user interfaces or networked sensor aggregation. Its CAN 2.0B peripheral is particularly attractive for in-vehicle networks and industrial fieldbus bridges. When designing with this part, ensure the configured oscillator (HS, EC, or PLL) matches the chosen 25 MHz or 40 MHz operation mode, and follow Microchip AN822 (flash programming) and the PIC18 configuration bits reference for in-circuit serial programming.

典型應用
PIC18F8627-E/PT 適用於 6 應用s: Industrial Control Panels (HMI / PLC), Automotive Body & HVAC Modules, Building Automation Gateways, Medical Instrument Controllers, Consumer Appliance Controllers, Sensor Aggregation & Data Logger Nodes.
Industrial Control Panels (HMI / PLC)
The PIC18F8627-E/PT is well-suited to industrial HMI and PLC front-end controllers because it integrates 70 digital I/O pins for direct keypad, LED, and 7-segment multiplexing without external buffers. Its 96 KB flash holds ladder-logic interpreters, Modbus RTU slave stacks, and graphical UI bitmaps, while the 4.2-5.5 V supply range pairs cleanly with 24V-to-5V industrial rails. Two USARTs enable simultaneous RS-485 Modbus and RS-232 debug console, and the Enhanced CAN 2.0B peripheral is ready for CANopen slave or DeviceNet bridge roles.
推薦
Automotive Body & HVAC Modules
In automotive body controllers, climate-control modules, and instrument clusters, the PIC18F8627-E/PT's Enhanced CAN 2.0B module communicates directly with the vehicle bus, while the 70 I/O pins drive relays, blower motors, and stepper-motor driver stages. The extended -40 C to +125 C temperature grade covers under-dash and engine-bay-adjacent installations per AEC-Q100-style Microchip testing. The 96 KB flash comfortably absorbs CAN-based diagnostic stacks such as UDS or KWP2000, leaving headroom for LIN slave implementations on the MSSP peripheral.
推薦
Building Automation Gateways
Building-automation gateways aggregate multiple fieldbuses (BACnet MS-TP, Modbus RTU, KNX, LonWorks) and forward data to IP networks, and the PIC18F8627-E/PT is a strong fit thanks to its two USARTs and Enhanced CAN module on a single chip. The 96 KB flash runs BACnet/IP and Modbus TCP firmware stacks, while the MSSP peripheral handles SPI-driven Ethernet controllers such as the ENC28J60. Extended-temperature operation tolerates rooftop and unconditioned mechanical-room enclosures.
推薦
Medical Instrument Controllers
Medical instrumentation such as infusion pumps, blood-pressure monitors, and portable analyzers benefits from the PIC18F8627-E/PT's deterministic PIC18 instruction set, on-chip 10-bit ADC for sensor signal conditioning, and 96 KB flash for safety-critical firmware. The extended-temperature rating supports both clinical and field-emergency environments, and the CAN peripheral enables integration with hospital bed networks or device clusters. The nanoWatt power-management modes extend battery life in portable designs.
推薦
Consumer Appliance Controllers
White-goods appliances (washing machines, dishwashers, ovens, refrigerators) deploy the PIC18F8627-E/PT as the main controller because 70 I/O pins drive motor triacs, solenoids, valve relays, and TFT/LCD displays without external bus expanders. The Enhanced CAN peripheral is increasingly used for appliance networking in premium models, and the 96 KB flash accommodates proprietary wash-cycle algorithms and over-the-air update stubs. Wide 4.2-5.5 V supply aligns with rectified-mains-derived 5 V rails.
推薦
Sensor Aggregation & Data Logger Nodes
Industrial sensor-aggregation nodes that sample multiple analog inputs, time-stamp events, and forward over CAN or RS-485 lean on the PIC18F8627-E/PT's 10-bit ADC (multiple channels), 70 I/O for parallel sensor arrays, and dual USARTs for sensor + debug channels. The 3,936-byte SRAM holds circular buffers for event logs before flushing to external EEPROM, and 96 KB flash holds the Modbus or CANopen slave stack. Extended-temperature tolerance supports outdoor and factory-floor deployments.

設計說明
Power the PIC18F8627-E/PT from a regulated 5 V rail with at least one 100 nF ceramic decoupling capacitor placed within 5 mm of each Vdd/Vss pair on the 80-pin TQFP; add a 10 uF bulk tantalum or ceramic cap on the main Vdd plane. AVdd/AVss should be sourced from a low-noise LDO (e.g. MCP1700) when using the 10-bit ADC to avoid reference drift. Brown-out reset (BOR) and low-voltage detect (LVD) must be enabled in configuration bits for industrial safety.
Estimated: at maximum 40 MHz CPU speed with all peripherals enabled and I/O toggling at 5 V, the PIC18F8627-E/PT typically dissipates under 250 mW; with the 80-pin TQFP thermal resistance around 50 C/W (per Microchip packaging notes), junction temperature rise is modest for room-temperature operation. In extended-temperature deployments at +125 C ambient, ensure peripheral current does not exceed the datasheet I/O sink/source ratings (typically 25 mA per pin, 200 mA per port group). Provide adequate copper pour to dissipate self-heating.
Layout the 80-pin TQFP with a continuous ground plane on the top or bottom layer to provide low-impedance return paths for switching I/O. Keep crystal traces short and symmetric; route the ICSP PGC/PGD lines (RB6/RB7) away from high-current switching nets to avoid programming glitches. Place the CAN transceiver (e.g. MCP2551 or TJA1050) within 50 mm of RF0 (CANRX) / RF1 (CANTX) and add a TVS diode on the bus lines for automotive EMC compliance.
Common pitfalls when designing with the PIC18F8627-E/PT: (1) forgetting to disable the analog inputs (PCFG bits in ADCON1) on pins used as digital I/O, which leaves them floating; (2) omitting the MCLR pull-up resistor (typically 10 kohm to Vdd) and thus allowing spurious resets; (3) leaving the ICSP pins unisolated from application circuits, which can load the programmer; (4) configuring PLL mode without proper configuration-bit setup, leading to no oscillator start. Always review CONFIG1H through CONFIG5L/5H against Microchip AN822 programming notes.
