PIC18F67K22-I/MR 概要
What is a microcontroller? A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), working RAM, and a rich set of peripherals (ADC, timers, communication ports, I/O). The PIC18F family uses Microchip's enhanced 8-bit Harvard RISC architecture with 16-bit opcodes, offering 200 ns instruction execution at 40 MHz. MCUs sit at the core of embedded systems, taking sensor inputs, running application firmware, and driving actuators or displays.
Key features of the PIC18F67K22 include 54 digital I/O pins, an integrated 12-bit A/D converter with up to 16 channels, a Charge Time Measurement Unit (CTMU) that simplifies capacitive-touch and capacitive sensing designs, multiple EUSART, I2C, and SPI ports, and the nanoWatt XLP technology suite that delivers sleep currents in the nanoampere range. The 1.4 KB of data EEPROM provides non-volatile storage for calibration, configuration, and user data separate from the main program Flash.
The device uses a modified Harvard architecture with separate code and data buses, executed through a C-optimizing compiler ecosystem. Up to 16 MIPS peak performance at 64 MHz supports real-time control loops. The CTMU peripheral allows time-based current integration for measuring capacitance, supporting mTouch touch sensing without external analog front ends.
Typical applications include capacitive-touch user interfaces, industrial sensor conditioning, low-power wireless sensor nodes, smart meters, home appliances, automotive body controllers, and USB peripherals (with the on-chip full-speed USB 2.0 device transceiver). The wide operating voltage range from 1.8V to 5.5V supports both 3.3V and 5V designs.
When designing with this part, note that the VQFN-9x9 footprint demands careful PCB layout with a properly sized thermal/exposed pad. The device is available in industrial (-40C to +85C) and extended (-40C to +125C) temperature grades.

主な用途
PIC18F67K22-I/MR の用途: 6 件s: Capacitive Touch User Interface, Battery-Powered Wireless Sensor Node, Industrial Process Sensor Conditioning, Smart Meter / Energy Measurement, USB HID Peripheral / Consumer Device, Home Appliance Control Board.
Capacitive Touch User Interface
The PIC18F67K22-I/MR is ideal for capacitive-touch user interfaces thanks to its integrated Charge Time Measurement Unit (CTMU), which delivers constant-current sourcing and timing measurement for mTouch capacitive sensing. The 54 I/O pins support 20+ touch electrodes including sliders and proximity zones without an external analog front-end IC. With 128 KB Flash and 4 KB RAM, firmware can include Microchip's mTouch library, GUI state machines, and noise-immunity algorithms.
おすすめ
Battery-Powered Wireless Sensor Node
The nanoWatt XLP technology in the PIC18F67K22-I/MR delivers sleep currents in the nanoampere range, making the device well-suited for battery-powered wireless sensor nodes. The CTMU can periodically wake the core for sensor sampling while the on-chip 12-bit ADC conditions transducer signals. The 1.8 V minimum supply voltage supports single-cell lithium or 2x AA operation with wide derating margin. EUSART, I2C, and SPI ports connect directly to radios like the MRF24J40 or RN2483 LoRa modules.
おすすめ
Industrial Process Sensor Conditioning
The PIC18F67K22-I/MR's 12-bit ADC with up to 16 input channels can directly digitize industrial sensor outputs including 4-20 mA loops, RTD bridges, and thermocouples. The 64 MHz CPU executes digital filters (FIR/IIR) and PID control loops at sub-millisecond period. The 1 KB EEPROM stores calibration coefficients per channel. Multiple EUSART ports enable simultaneous Modbus RTU master and HMI link operation. Industrial -40C to +85C rating supports factory-floor deployment.
おすすめ
Smart Meter / Energy Measurement
The CTMU and 12-bit ADC combination in the PIC18F67K22-I/MR supports metrology-grade measurement of voltage and current for single-phase smart meters. The 16 MIPS throughput executes IEC 62053-22 class-1 energy calculations in real time, while the 1 KB EEPROM logs tamper events and tariffs. The wide 1.8 V to 5.5 V supply supports battery-backed RTC operation during power outages. nanoWatt XLP idle modes extend coin-cell backup life to 10+ years.
おすすめ
USB HID Peripheral / Consumer Device
The PIC18F67K22-I/MR integrates a full-speed USB 2.0 device transceiver, eliminating an external USB PHY and supporting HID, CDC, and vendor-class device stacks. With 128 KB Flash and 4 KB RAM, Microchip's MLA USB library fits comfortably alongside application code. The 54 I/O pins drive LEDs, key switches, and actuators in HID peripherals such as keyboards, custom input devices, and audio controllers. VQFN-64 9x9 mm footprint suits compact consumer enclosures.
おすすめ
Home Appliance Control Board
The PIC18F67K22-I/MR is a strong fit for home-appliance controllers (washing machines, dishwashers, induction cooktops) thanks to its 54 I/O pins driving triac interfaces, motor PWM, and segmented LCDs. The 12-bit ADC reads thermistor inputs and motor current sensing for closed-loop control. The 1 KB EEPROM stores user cycle selections across power cycles. nanoWatt XLP modes minimize standby power to <0.5 W to meet global energy regulations. Operating temperature range -40C to +85C covers appliance kitchens and laundry rooms.

設計ノート
The VQFN-64 9x9 mm package has an exposed thermal pad (EP, pin 64) that must be soldered to a copper pour on the PCB. Soldering the EP improves thermal dissipation (helping the part meet industrial -40C to +85C specs) and provides a low-impedance ground reference. Star-ground multiple VSS pins to the EP pour with short, wide traces. Use a 0.1 uF ceramic bypass capacitor within 3 mm of each VDD pin cluster.
Place the 32.768 kHz crystal on SOSCO/SOSCI (RC1/RC0) as close to the MCU as possible with short traces and a guard ring tied to ground. The USB D+/D- pins (located on the K2x family on dedicated pins) require 90-ohm differential routing, matching length within 150 mil, and a common-mode choke for EMI compliance. Use Microchip's ANSEL/HID/CDC firmware stack guidelines for USB layout reference.
Do not exceed 5.5 V on any VDD pin or 5.5 V on any I/O pin - the K2x family is NOT 5V-tolerant on all pins when VDD is at 3.3 V. Verify the ICDSP programming pins (RB6/PGC, RB7/PGD) are not loaded down by external circuitry during programming. Do not leave MCLR floating; pull MCLR up through a 10 kohm resistor to VDD or use Microchip's internal MCLR configuration.
The PIC18F67K22-I/MR supports nanoWatt XLP modes. Use Sleep mode aggressively for battery-powered sensor applications - wake on RTCC alarm, CTMU threshold, or external interrupt. For high-throughput USB applications, switch to HS-PLL mode before USB enumeration to ensure full-speed USB timing. Place a 10 uF tantalum or ceramic bulk capacitor near the VDD pins to handle USB inrush current.
