PIC18F67K40-E/PT Overview
An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, integrating CPU, volatile and non-volatile memory, peripherals and interrupt logic on one die. The PIC18 family uses an enhanced RISC Harvard architecture with a 16-bit instruction word, C-compiler friendly instruction set and on-chip peripherals such as Core Independent Peripherals (CIPs) that can execute logic, timing, PWM and communications without CPU intervention.
Key features of the PIC18F67K40 include eXtreme Low Power (XLP) technology with sub-uA sleep currents, 5 V tolerance on most digital I/O, an integrated 12-bit ADC with computation (ADC2), multiple UART/SPI/I2C peripherals, PWM, Complementary Waveform Generator (CWG), CRC/SCAN memory scan, Windowed Watchdog Timer (WWDT), and hardware touch (CTMU) capable I/O. The 64-pin TQFP exposes up to 60 I/O pins for ample user connectivity.
Architecturally, the PIC18F67K40 combines a 16-bit program-word Flash with 8-bit data path, a 31-level hardware stack, and on-chip instruction trace support via a debug interface. Internal PLL allows selectable system clocks up to 64 MHz while the XLP sleep mode retains RAM at <1 uA, making it ideal for battery powered sensor nodes.
Typical applications include industrial control panels, home appliance HMI, low-power IoT sensor nodes, automotive body and climate modules, and USB/HID peripherals using the on-chip FS USB transceiver. Designers frequently use the PIC18F67K40 in human-machine interface boards, motor control command front-ends and sensor aggregation hubs.
When designing in this part, leave the reserved pins (OSC1/OSC2/VDD/VSS pairs) on the 64-pin TQFP well-bypassed with 0.1 uF and 10 uF capacitors; the debug pins PGC/PGD should be brought to a 5-pin header for in-circuit serial programming. Pick PIC18F67K40-I/PT instead if your thermal environment does not exceed +85 °C.

Typical Applications
PIC18F67K40-E/PT is suitable for 6 applications: Industrial Control Panel HMI, Home Appliance Front Panel, Battery Powered IoT Sensor Node, Automotive Body and Climate Module, USB HID Peripheral Device, Motor Control Command Front-End.
Industrial Control Panel HMI
The PIC18F67K40-E/PT's 128 KB Flash accommodates full HMI state machines and graphics tables, while 8 KB RAM supports input debounce buffers and LCD frame buffers. The 12-bit ADC2 with computation scans up to 60 I/O for keypad, rotary encoder and analog sensor inputs.

Home Appliance Front Panel
Washing machines, dishwashers and ovens use the PIC18F67K40-E/PT to drive 7-segment LED or character LCD displays and to scan capacitive touch buttons via the on-chip CTMU. The 64-pin TQFP provides ample I/O to drive motor relays, triac triggers and door-lock solenoids directly through high-current capable pins. The FS USB enables factory firmware updates and diagnostic logs over a service port. XLP sleep currents under 1 uA keep standby power below the 0.5 W energy limits mandated by ecodesign regulations. The 64 MHz core executes IEC 60730 safety class B self-test routines within a few hundred microseconds. Pair with the MCP1700 LDO and AT24CM02 EEPROM for non-volatile fault logs.

Battery Powered IoT Sensor Node
The PIC18F67K40-E/PT's eXtreme Low Power XLP technology delivers sub-uA sleep currents while retaining RAM, enabling multi-year coin-cell life for environmental sensors, smart locks and metering edge nodes. The 12-bit ADC2 with averaging and threshold interrupts wakes the core only on threshold crossings to preserve energy. Multiple I2C and SPI peripherals fan out to environmental, motion and gas sensors simultaneously. The 2.3-5.5 V VDD range supports both single-cell Li-ion and 3 V coin-cell chemistries without level shifters. Core Independent Peripherals execute sensor polling, watchdog refresh and PWM dimming without CPU wake-up. Pair with the MCP9808 temperature sensor and RN4870 BLE module for wireless IoT nodes.

Automotive Body and Climate Module
The PIC18F67K40-E/PT -E temperature grade spans -40 °C to +125 °C, suiting under-dash and engine-bay-adjacent body controllers for lighting, mirror adjust, seat control and HVAC blend doors. The 12-bit ADC reads potentiometers and thermistors for climate control feedback, while PWM outputs drive brush DC motor bridges for blend doors and blowers. LIN stack via UART enables low-cost automotive networking with BCMs. The hardware CRC and Memory Scan CIPs meet ASIL-QM functional safety self-test requirements for body domain controllers. Designers pair the part with the MCP2515 CAN-FD controller for chassis bus bridging and ATA663231 LIN transceiver for body electronics.
Recommended
USB HID Peripheral Device
The PIC18F67K40-E/PT's integrated Full-Speed USB 2.0 peripheral with on-chip transceiver enables HID-class devices such as custom keyboards, programmable control surfaces, foot pedals and barcode scanners without external USB PHY chips. The 128 KB Flash stores HID descriptors, macro definitions and dual-boot firmware update images, while 8 KB RAM holds HID reports and ring buffers. The 5 V-tolerant I/O can directly interface with mechanical switches and optocouplers for industrial foot switches. Core Independent Peripherals handle USB endpoint servicing, debounce and LED indicator PWM without CPU intervention. Pair with the MCP2221A USB-to-UART bridge for legacy RS232 peripherals and AT25SF081 flash for HID macro storage.
Recommended
Motor Control Command Front-End
The PIC18F67K40-E/PT executes high-level command arbitration and protection logic for brushless DC or stepper motor front-ends, while dedicated PWM and CWG peripherals generate the timing waveforms. The 64 MHz instruction rate provides sub-microsecond response to current-sense faults via the 12-bit ADC2 with computation thresholds. Quadrature encoder inputs on dedicated pins close position loops for stepper and servo applications. The FS USB enables host-side configuration and live tuning over a service port. Pair with the dsPIC33CK for high-performance FOC loops and the DRV8323 gate driver for three-phase BLDC stages.

Design Notes
Place a 0.1 uF decoupling capacitor within 5 mm of every VDD pin (11 and 32) and a single 10 uF bulk capacitor on the AVDD supply rail. For USB operation, the VUSB pin must be tied to VDD through a 10 uF capacitor and the D+/D- lines require 27 ohm series resistors per the USB specification to meet FS edge rates.
Keep the 64-pin TQFP footprint with 0.5 mm pitch and an exposed die pad for thermal dissipation. Route the PGC and PGD pins to a 5-pin ICSP header (MCLR, VDD, GND, PGC, PGD) placed at the board edge for in-circuit serial programming without removing the MCU. The exposed thermal pad must be soldered to a copper pour of at least 25 mm^2 for thermal relief at full 64 MHz operation.
Do not leave unused I/O pins floating - configure them as outputs driving low to eliminate shoot-through current in XLP sleep mode. The MCLR pin should be tied to VDD through a 10 kohm pull-up; do not leave it floating. A 100 nF capacitor on MCLR is recommended to suppress ESD-induced resets. Verify the PLL settings against the oscillator configuration bits to avoid lockup at startup.
Isolate the analog AVDD/VSS pair with a ferrite bead from the digital VDD/VSS supply to keep ADC2 measurements clean. Place the 12-bit ADC reference capacitor (0.1 uF) adjacent to the VREF+ pin. For CTMU touch applications, route touch electrodes with a guard ring tied to a quiet analog ground to maximize touch SNR.
Compliance Information
RoHS and REACH compliant per Microchip product page. AEC-Q100 is not applicable - this part is qualified to industrial -E grade (-40 to +125 °C) only; for AEC-Q100 automotive, select a VAO-suffixed variant.
