PIC18LF8627T-I/PT - 8-Bit MCU, 96KB Flash, 80-TQFP | Microchip
MPN: PIC18LF8627T-I/PT ✓ فعالPIC18LF8627T-I/PT نمای کلی
A PIC microcontroller (MCU) is a compact integrated circuit that combines a CPU core (in this case an enhanced PIC18 RISC architecture), programmable FLASH memory, RAM, EEPROM, and a rich set of digital and analog peripherals in a single chip. PIC18F-family MCUs sit in the middle of Microchip's 8-bit portfolio: more capable than the PIC16F baseline series and PIC12/16 mid-range, but below the 16-bit PIC24/dsPIC and 32-bit PIC32 families. They are widely adopted in industrial control, automotive sub-systems, consumer appliances, and sensor-based embedded designs where deterministic behavior and ease of programming (via MPLAB X) matter more than raw computational throughput.
Key features of the PIC18LF8627T-I/PT include 96KB (48K x 16) of self-programmable FLASH for code storage, 4KB of SRAM, 1KB of EEPROM data memory, 70 general-purpose I/O pins, multiple 10-bit ADC modules, PWM, USART, I2C, SPI, USB and CAN peripherals, and an operating frequency up to 40 MHz (10 MIPS). The TQFP-80 (12x12 mm) package provides ample I/O count for human-machine interface (HMI), motor control, and instrumentation.
Architecture-wise, the part uses a 16-bit instruction word with an 8-bit data path, an enhanced instruction set, hardware multiply, and a 32-level deep hardware stack, enabling efficient C-code generation while retaining the predictable interrupt latency PIC MCUs are known for. The 10 MIPS performance combined with nanoWatt power management makes it suitable for both line-powered and battery-powered designs.
Typical applications include industrial automation controllers, automotive body and HVAC modules, medical instrumentation front-ends, consumer appliance control boards, and USB/CAN-connected sensor hubs. The wide I/O count and rich peripheral mix make it a strong fit where a single chip must consolidate several legacy functions.
When designing with this MCU, plan oscillator and decoupling layout early, keep analog and digital grounds partitioned, and verify the CAN/USB bus termination against IEC 61000-4-2 ESD expectations in your enclosure. Engineers migrating from PIC16F should review the extended instruction set and the new peripheral libraries in MPLAB XC8.

کاربردهای معمول
PIC18LF8627T-I/PT مناسب است برای 7 کاربردs: Industrial Automation Controller, Automotive Body Control Module, Medical Instrumentation Front-End, Consumer Appliance Control Board, USB/CAN Sensor Hub, HMI Display Controller, Data Acquisition / Test Equipment.
Industrial Automation Controller
The PIC18LF8627T-I/PT's 70 I/O pins and integrated CAN 2.0B peripheral make it a strong fit for industrial PLC and distributed I/O nodes. Its 96 KB FLASH accommodates ladder-logic interpreters, Modbus/CANopen stacks, and the 4 KB SRAM buffers protocol frames efficiently. At 40 MHz (10 MIPS), the part handles deterministic scan loops with sub-millisecond response. Pair it with an MCP2551 CAN transceiver and TVS arrays for IEC 61000-4-2/4 ESD/surge compliance.

Automotive Body Control Module
In automotive body and HVAC modules the PIC18LF8627T-I/PT provides LIN/CAN connectivity for door, seat, and climate subsystems. The 70 I/O drive multiple FET bridges and sensor inputs, while the 10-bit ADC reads thermistor/position feedback. The industrial -40C to +85C grade covers cabin environments; for under-hood use, step up to the PIC18F8627T-E/PT (E-temperature, -40C to +125C). The 96 KB FLASH supports OEM-specific calibration tables.

Medical Instrumentation Front-End
The PIC18LF8627T-I/PT serves as a sensor aggregation and user-interface MCU in portable medical devices such as glucose meters and pulse-oximeter base stations. Its 70 I/O support TFT/LCD drive, keypad scanning, and analog front-end interfacing. The integrated USB peripheral simplifies data upload to a host PC, while the LF core allows battery operation from a single Li-ion cell. Verify your design against IEC 60601-1 isolation requirements separately.

Consumer Appliance Control Board
For washing machines, dishwashers, and induction cooktops, the PIC18LF8627T-I/PT consolidates HMI control, motor drive signaling, and safety monitoring in one chip. The 96 KB FLASH holds appliance-state machines and fault logs in EEPROM. Multiple PWM channels drive TRIAC/MOSFET gate signals. Its nanoWatt power-down modes help meet ENERGY STAR idle budgets. The wide I/O count eliminates the need for an external I/O expander.

USB/CAN Sensor Hub
The PIC18LF8627T-I/PT's combined USB 2.0 full-speed and CAN 2.0B peripherals make it ideal for a bridge hub that aggregates sensor data over CAN and exposes it to a host PC via USB. Its 70 I/O connect to multi-channel sensor front-ends, while the 4 KB SRAM ring-buffers CAN traffic. At 40 MHz the part keeps up with 1 Mb/s CAN-FD frames (limited to arbitration phase) and USB polling intervals without dropping frames.
پیشنهادی
HMI Display Controller
The 70 I/O count and 96 KB FLASH make the PIC18LF8627T-I/PT a capable HMI controller for low-to-mid resolution TFT panels and character LCDs. It generates bit-mapped graphics, scans keypads, and drives LEDs through PWM. Combined with the PIC18F family reference manual's PMP/EPMP peripheral documentation, the part can address 8080-interface panels directly. The USB peripheral supports touch-screen firmware updates from a PC.
پیشنهادی
Data Acquisition / Test Equipment
For bench-top data loggers and laboratory instruments, the PIC18LF8627T-I/PT acts as the control MCU that streams 10-bit ADC samples over USB to a host PC. Its 70 I/O accommodate multiple sensor input multiplexers, while the 4 KB SRAM ring-buffers sample bursts. The LF voltage range supports battery-powered field instruments. On-board EEPROM stores calibration coefficients for traceable measurements.

یادداشت‌های طراحی
The PIC18LF8627T-I/PT has multiple VDD/VSS pairs (pins 10/11, 20/21, 38/44, 76/77). Decouple each VDD pair with a 100 nF ceramic placed within 3 mm of the pin, plus a bulk 10 uF tantalum near the package. Tie AVDD/AVSS to the same rail with a ferrite bead or 10 ohm resistor to isolate analog from digital noise; place a separate 100 nF on AVDD. This decoupling layout is essential for reliable USB and CAN operation per Microchip's PIC18F8627 datasheet recommendations.
Do not leave MCLR floating - always tie it through a 10 kohm pull-up to VDD with a 100 nF cap to ground for noise immunity. The ICSP pins RB6/PGC and RB7/PGD must be accessible in production (test pads or header) for in-field firmware updates. Failure to disable unused peripherals in firmware via the PMD registers can increase I_DD by 1-3 mA, which matters for battery-powered designs. According to Microchip's errata DS80000483, certain silicon revisions require workaround code for the ADC in sleep mode.
Route the 40 MHz crystal traces (OSC1/OSC2, pins 1-2) as short as possible with a ground guard ring, and keep them away from high-edge-rate signals like PWM outputs and CAN. The USB D+/D- traces require 90 ohm differential impedance and should not fork; route them on the top layer over a continuous ground plane. CAN CANTX/CANRX should also be routed with a ground guard, as recommended in Microchip's AN1249 'USB CDC Class on PIC18F' and AN215 'CAN Physical Layer'.
When using the integrated USB peripheral, ensure the D+/D- lines have 90 ohm differential impedance and a 15 kohm pull-down on D- (for host detection). The on-chip USB regulator requires a 220 nF bypass on VUSB. For CAN, place a 120 ohm termination resistor at each end of the bus and use a twisted pair. Both buses benefit from TVS arrays such as USBLC6-2SC6 (USB) and PESD1CAN (CAN) for automotive-grade ESD/surge protection.
