PIC18F67K22-I/PTRSL Visão geral
What is a PIC18 microcontroller? The PIC18 family is Microchip's high-performance 8-bit RISC architecture line, optimized for low power, robust peripherals, and a long product lifecycle, sitting above the baseline PIC16 and PIC12 families in Microchip's 8-bit portfolio. XLP (eXtreme Low Power) nanoWatt technology refers to a set of clocking, sleep mode, and peripheral gating techniques that allow sleep currents in the nanoamp range while retaining RAM and fast wake-up for battery-powered and energy-harvesting applications.
Key features include the nanoWatt XLP sleep current of approximately 20 nA, an active current of about 8 mA at 64 MHz, a CTMU peripheral for capacitive touch and precise time measurement, an Enhanced Universal Synchronous/Asynchronous Receiver/Transmitter (EUSART), two MSSP ports for SPI/I2C, multiple 16-bit timers, capture/compare/PWM modules, and a 12-bit A/D converter with up to 16 channels. The part also supports self-programming and an integrated LCD driver option on related die variants.
Technically, the PIC18F67K22 family uses a modified Harvard architecture with a 16-bit instruction word and 8-bit data path, executed through a 2-stage pipeline at 4 clock cycles per instruction. Internal oscillator options support 16 MHz to 64 MHz operation with PLL, providing clock accuracy suitable for UART communication without external crystals in many designs. The wide 1.8V-5.5V supply range enables direct operation from Li-Ion or two AA cells in portable designs.
Typical applications include capacitive touch user interfaces with the CTMU, battery-powered remote sensors with nanoWatt XLP, industrial control panels with 12-bit measurement, USB-enabled human interface devices when paired with an external transceiver, LCD-based consumer appliances, and automotive body/comfort modules using the wider PIC18 K-series derivatives.
When designing with this device, ensure proper decoupling with a 100 nF ceramic capacitor close to each VDD pin and a bulk capacitor on the regulated rail. The CTMU requires careful PCB layout and a reference current calibration step for accurate capacitive touch readings, and unused I/O pins should be configured as outputs low to minimize quiescent current.

Aplicações típicas
PIC18F67K22-I/PTRSL é adequado para 6 aplicaçãos: Capacitive Touch HMI, Battery-Powered Remote Sensor, Industrial Control Panel, USB HID Peripheral, Home Appliance with LCD Display, Automotive Body / Comfort Module.
Capacitive Touch HMI
The PIC18F67K22-I/PTRSL's integrated CTMU (Charge Time Measurement Unit) provides hardware-assisted capacitive touch sensing that measures sub-picofarad capacitance changes with a single calibration reference current. The 12-bit ADC with up to 16 channels can scan a touch matrix of 16 electrodes in a few milliseconds, while the 128 KB Flash comfortably holds a touch library plus application firmware. With 53 I/O pins on the 64-pin TQFP, designers can wire 4x4 or 5x5 touch matrices plus LEDs, a display interface, and a host UART without external GPIO expanders. The nanoWatt XLP sleep mode drops the MCU to roughly 20 nA between scans, enabling battery-powered remote controls and wireless touch panels that wake on a single electrode interrupt.
Recomendado
Battery-Powered Remote Sensor
The PIC18F67K22-I/PTRSL nanoWatt XLP technology delivers sleep currents of approximately 20 nA with RAM retention, enabling multi-year battery life on a single 3V coin cell when the MCU wakes every few seconds to read a sensor and transmit via UART or SPI. The 1.8-5.5V supply range supports direct Li-Ion, two-AA, or regulated 3.3V rails. The 12-bit ADC and CTMU handle resistive bridge sensors, thermistors, and capacitive humidity elements without an external signal chain. The 128 KB Flash allows on-chip protocol stacks for Sub-GHz transceivers, and the 64-pin TQFP footprint fits standard sensor-node PCB reference designs from Microchip application notes.
Recomendado
Industrial Control Panel
The PIC18F67K22-I/PTRSL suits industrial control panels that require 12-bit measurement of multiple analog signals (temperature, pressure, current) plus a user interface of buttons, LEDs, and a character LCD. The 12-bit ADC with up to 16 channels handles 4-20 mA loop inputs via burden resistors and direct thermocouple/thermistor digitization with proper signal conditioning. The two EUSARTs and two MSSP ports allow simultaneous RS-485 Modbus communication and SPI-connected peripherals such as digital potentiometers or EEPROM. The -40C to +85C industrial temperature range covers most factory-floor enclosures, and the 64-pin TQFP offers 53 I/O lines for keypad matrix, LED drivers, and discrete control outputs.
Recomendado
USB HID Peripheral
When paired with an external USB transceiver, the PIC18F67K22-I/PTRSL can act as a USB Full-Speed HID peripheral such as a keyboard, mouse, custom joystick, or measurement dongle. The 128 KB Flash and 4 KB RAM fit USB HID class drivers plus application logic, and the 12-bit ADC can digitize analog sensors for HID telemetry reports. Two MSSP ports provide SPI for external peripherals and I2C for user-interface devices such as OLED displays. The 64-pin TQFP footprint simplifies PCB layout by exposing the full peripheral set on a single, easily-routed 0.5 mm pitch package.
Recomendado
Home Appliance with LCD Display
The PIC18F67K22 family drives segment LCDs through its integrated LCD controller peripheral (on die variants that include it), reducing BOM cost for washing machines, microwave ovens, and thermostats that need a multi-digit display. The 12-bit ADC reads temperature sensors, level probes, and motor current sense, while the multiple PWM modules drive motor or heater elements via MOSFET drivers. The 128 KB Flash comfortably fits a UI library, real-time clock, and safety state machine. The 64-pin TQFP keeps the design on a single PCB layer with the display tail connected via a single FPC.
Recomendado
Automotive Body / Comfort Module
The PIC18F67K22 family is widely used in non-safety automotive body and comfort modules such as seat controllers, mirror adjusters, and ambient lighting drivers. The -40C to +85C industrial grade covers cabin environments, and the K22 family has automotive-qualified E-grade (-40C to +125C) variants on the same die. The 12-bit ADC reads switch positions and lighting feedback, the PWM modules drive LED strings, and the EUSARTs/MSSP handle LIN bus or CAN-with-external-transceiver networking. The 64-pin TQFP supports the higher I/O count needed for multi-channel lighting and motor control.

Notas de projeto
Estimated: at VDD = 5.0V, the PIC18F67K22 active current is approximately 8 mA at 64 MHz per the family datasheet, yielding roughly 0.25 W in steady-state. Decouple VDD/VSS pairs with a 100 nF ceramic capacitor within 5 mm of each supply pin plus a 10 uF bulk capacitor on the rail; the AVDD/AVSS pair (pins 35/36 on the 64-pin TQFP) requires its own 100 nF + 10 uF to keep ADC noise below 1 LSB at full 12-bit conversion rate.
Route the MCLR reset line (pin 60) with a 10 kohm pull-up to VDD and place a 100 nF capacitor from MCLR to ground close to the pin for noise immunity. Keep the ICSP clock and data lines (RB6/RB7) away from high-frequency switching traces to prevent programming glitches; avoid long parallel runs with PWM outputs.
Do not leave any I/O pin floating - configure all unused pins as outputs driving low to minimize quiescent current in nanoWatt XLP sleep mode. The CTMU requires calibration of the reference current using a known capacitor before accurate touch readings can be obtained; consult Microchip application note AN1250 for the CTMU calibration procedure.
