PIC18F8627-I/PT - 8-Bit 40MHz 96KB Flash MCU | Microchip
MPN: PIC18F8627-I/PT ✓ AktifPIC18F8627-I/PT Ringkasan
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash/ROM), working memory (RAM), non-volatile data storage (EEPROM), and a rich set of peripherals onto one silicon die. PIC18 microcontrollers belong to the 8-bit reduced instruction set computing (RISC) class; they execute one instruction per clock cycle (4-clock instruction fetch plus 1-cycle execute at 40 MHz) and use a Harvard architecture with separate program and data buses. The PIC18F8627 is the top-of-family "enhanced flash" part, sitting one tier above the PIC18F6627 in flash density and feature set.
Key features of the PIC18F8627-I/PT include nanoWatt power-management technology with multiple idle and sleep modes, a hardware 8x8 multiplier, a 16-bit wide instruction word, ICD/ICSP in-circuit debugging, and industrial temperature grade operation (-40C to +85C). The wide 2.0V to 5.5V Vdd range and low-power sleep modes make it attractive for both line-powered and battery-backed designs. The internal oscillator block provides configurable 8 MHz to 32 MHz operation, reducing external component count.
Architecturally, the PIC18F8627-I/PT uses an enhanced flash memory cell that supports >10k erase/write cycles and >40-year data retention, with self-programmability under firmware control for bootloader-style field updates. The 10-bit ADC delivers up to 16 channels of conversion with a 100K samples/second aggregate rate, and the CTMU (Charge Time Measurement Unit) enables touch sensing and precise time-of-flight measurements.
Typical applications include industrial automation controllers, HVAC and building-management systems, automotive body and instrument-cluster ECUs, embedded CAN-node interfaces, motor-control front-ends, and consumer white-goods main controllers. The combination of CAN + multiple serial ports + abundant I/O positions it well for distributed control networks. Design consideration: at 80 pins the TQFP footprint requires a 4-layer PCB for clean signal routing, and unused I/O must be configured as outputs or pulled to defined states to minimize current draw.

Aplikasi Umum
PIC18F8627-I/PT cocok untuk 6 aplikasis: Industrial CAN-Bus Node Controller, HVAC and Building Management Controller, Automotive Body Electronics ECU, Color TFT LCD Graphics Controller, Three-Phase Motor Drive Front-End, Medical Device Sensor Aggregator.
Industrial CAN-Bus Node Controller
The PIC18F8627-I/PT is well suited to industrial CAN-bus nodes because of its integrated Enhanced CAN (ECAN) module with 2.0B active support and 8 acceptance filter/mask pairs, combined with 96 KB flash for protocol stacks such as CANopen or DeviceNet. At 5V Vdd and 40 MHz Fosc, the part sustains the standard 1 Mbps CAN bit rate without CPU bottleneck. Engineers typically pair the ECAN TX/RX pins with an MCP2551 or TJA1050 transceiver; the 70 GPIO handle additional digital I/O for sensors and actuator drives.

HVAC and Building Management Controller
The 16-channel 10-bit ADC and 4 KB RAM make the PIC18F8627-I/PT a strong fit for HVAC controllers that read multiple temperature, humidity, and pressure sensors while driving triacs for fan and damper actuators. With nanoWatt sleep modes, the MCU drops below 1 uA in deep sleep between sensor scans, extending battery life in wireless thermostats. The 2.0V to 5.5V Vdd range allows operation directly from a 3.3V backup rail during power-loss conditions.

Automotive Body Electronics ECU
The PIC18F8627-I/PT integrates the ECAN module and abundant I/O (70 pins) needed for body-control modules that manage lighting, door locks, wipers, and mirror control over a CAN bus. Although the I (industrial) temperature grade suits under-dash mounting, design teams must add external ESD protection (e.g. PESD1CAN) on bus lines. The 10-bit ADC is sufficient for battery voltage monitoring and thermistor-based temperature sensing.

Color TFT LCD Graphics Controller
The PIC18F8627-I/PT's 70 GPIO pins and 96 KB flash accommodate a TFT-LCD graphics library with touch handling, suitable for HMI panels up to 320x240 QVGA. The two MSSP peripherals provide SPI master operation to the LCD controller (e.g. ILI9341) and I2C to the capacitive touch controller. CTMU support enables resistive touch screen digitisation without an external ADC.
Direkomendasikan
Three-Phase Motor Drive Front-End
The PIC18F8627-I/PT can serve as the supervisory MCU in a three-phase inverter front-end, using its 3 CCP/ECCP modules for PWM generation to MOSFET drivers, and 16 ADC channels for back-EMF and current sensing. The 4 KB RAM supports space-vector modulation lookup tables and field-oriented control state variables. At 40 MHz the part delivers sufficient computational headroom for sensorless FOC on small BLDC motors up to several kW.

Medical Device Sensor Aggregator
Although the PIC18F8627-I/PT is not medical-grade certified, its industrial temperature range and reliable flash retention support non-critical medical peripherals such as patient-room environmental sensors, infusion pump user interfaces, and bedside monitoring aggregators. The 16-channel ADC with CTMU accurately digitises resistive bridge sensors (pressure, force) used in hospital equipment. Engineers should add external watchdog (e.g. MCP130T) for fail-safe reset behaviour.

Diferensiator Kunci
- Only Microchip 80-pin TQFP PIC18 with 96 KB flash and active lifecycle in 2026 (vsPIC18F8722-I/PT)
- Integrated ECAN 2.0B module with 8 filter/mask pairs (vsPIC18F8585-I/PT)
- Dual nanoWatt sleep modes with deep-sleep under 1 uA typical (vsPIC18F8527-I/PT)
Catatan Desain
The 80-pin TQFP (PT) 12x12 mm package has 0.5 mm pitch and benefits from a 4-layer PCB with dedicated ground and power planes to minimize EMI and provide stable Vdd to the high-pin-count die. Decouple each Vdd/Vss pair with a 100 nF ceramic cap placed within 3 mm of the pin pair, plus a single 10 uF bulk tantalum or ceramic at the board-level Vdd entry point. The TQFP thermal pad is not present on this package; rely on copper pours on the top layer connected to Vdd/Vss to dissipate the moderate heat generated at 40 MHz / 5V.
Always configure unused I/O pins as outputs driving low to minimize current consumption in sleep mode - floating inputs can draw 100 uA or more per pin through the CMOS input buffer. Configure the MCLR pin with the recommended 10 kohm pull-up and direct connection to the ICSP connector for in-circuit debugging. Brown-out reset (BOR) should be enabled in the configuration bits to prevent code execution at unsafe Vdd levels during power-up; the PIC18F8627-I/PT supports BOR at 2.0V, 2.7V, 4.2V, or 4.5V thresholds.
For the ECAN module the TX and RX traces to the CAN transceiver must be routed as a differential pair with 120 ohm characteristic impedance and matched lengths within 5 mm; place a 4.7 nF split-termination across the bus as close to the transceiver as possible. The ICSP/ICD pins (PGC/PGD on RB6/RB7) should have series 4.7 kohm resistors to isolate the debugger from the application circuit during production, otherwise debug sessions can disturb sensitive analog measurements on adjacent PORTB pins.
