PIC18F67K22-I/PT Visão geral
A microcontroller (MCU) is a single-chip computer containing a CPU core, program and data memory, I/O peripherals, and interrupt logic. The PIC18F family sits within the broader 8-bit PIC microcontroller hierarchy from Microchip, occupying the high-performance tier above the PIC16 and baseline PIC10/12/14 families. XLP technology is a suite of power-management modes (including nanoWatt XLP sleep currents down to 300 nA) that make this MCU well suited to battery-powered and energy-harvesting applications where quiescent draw dominates battery life.
Key differentiating features include 64 MHz maximum clock speed (with a 16 MIPS instruction throughput at that rate), 53 digital I/O pins, a 12-bit A/D converter capable of up to 100 ksps, two analog comparators, a 16-bit timer/counter module with PWM, and CTMU hardware for touch and time-of-flight measurements. The wide operating voltage range of 1.8 V to 5.5 V supports both 3.3 V and 5 V system designs without external level translation. The PIC18F67K22-I/PT is the industrial temperature grade (-40C to +85C) variant in the 64-pin TQFP package.
Architecturally, the device uses an enhanced Harvard architecture with separate program and data buses, a 16-bit instruction set, and hardware multiplier for faster arithmetic than baseline PIC cores. The integrated nanoWatt XLP modes (Run, Idle, Sleep, and RTCC) and the RTCC module (with dedicated 32 kHz crystal support) provide fine-grained control over active and standby power budgets. Brown-out Reset (BOR), Watchdog Timer (WDT), and Power-on Reset (POR) hardware ensure reliable start-up in noisy industrial environments.
Typical applications include capacitive touch user interfaces, battery-powered sensor nodes, industrial control panels, low-power metering, USB device peripherals (using the 8-bit USB-capable sibling PIC18F46K22 or external transceiver), automotive body electronics (with the extended-grade variant), and embedded HMI displays. The CTMU peripheral simplifies capacitive touch button and slider implementations by measuring charge time rather than requiring an external timer IC.
When designing with this part, pay attention to the in-circuit serial programming (ICSP) pins and provide a robust decoupling network (100 nF + 10 uF near VDD) to keep the analog and digital rails clean. The 64-pin TQFP footprint is shared with many PIC18F siblings, allowing in-package migration to PIC18F87K22 or down-migration to PIC18F47K22 with minimal PCB rework.

Aplicações típicas
PIC18F67K22-I/PT é adequado para 7 aplicaçãos: Capacitive Touch User Interface, Battery-Powered Sensor Node, Industrial Control Panel, Low-Power Metering, Embedded HMI Display, Automotive Body Electronics, USB Device Peripheral.
Capacitive Touch User Interface
The PIC18F67K22-I/PT fits capacitive touch UI designs through its integrated CTMU peripheral, which measures charge time on capacitive sense electrodes to detect finger proximity without an external timer IC. With 53 I/O pins available in the TQFP-64 package, the MCU can scan 20+ touch electrodes while leaving sufficient I/O for LEDs, haptics, and a host interface. The 16 MIPS throughput handles Microchip's mTouch firmware library at typical 25-50 Hz scan rates, and the nanoWatt XLP sleep mode keeps touch-active standby current below 300 nA, enabling battery-powered remote controls and white-good HMI panels.
Recomendado
Battery-Powered Sensor Node
For battery-powered sensor nodes, the PIC18F67K22-I/PT delivers the right balance of low quiescent draw and computational headroom. Through its nanoWatt XLP sleep mode, the MCU pulls less than 300 nA in deep sleep while still maintaining RTCC operation, allowing multi-year battery life in metering and remote-monitoring applications. The 12-bit ADC with 16 channels handles thermocouple, ratiometric sensor, and battery-voltage measurements at 100 ksps, while the 128 KB Flash fits complete Microchip MiWi or Modbus RTU protocol stacks alongside application code, eliminating the need for an external 16-bit MCU.
Recomendado
Industrial Control Panel
The PIC18F67K22-I/PT is well-matched to industrial control panels because of its wide 1.8-5.5 V operating range and rugged 5V-tolerant I/O. Through its EUSART (with LIN support), SPI, and I2C peripherals, the MCU communicates concurrently with sensor front-ends, display drivers, and isolated RS-485 transceivers. The 53 I/O lines drive matrix keypads, status LEDs, character LCDs, and buzzer PWM without external logic. Industrial-grade -40C to +85C operation, BOR/POR/WDT supervisory hardware, and 64-pin TQFP package availability make the part a drop-in solution for HMI panels and machine-control boards.
Recomendado
Low-Power Metering
For gas, water, and electricity meters, the PIC18F67K22-I/PT's combination of CTMU, 12-bit ADC, and XLP sleep modes is highly attractive. Through its CTMU peripheral, the MCU performs precision time-of-flight measurements on ultrasonic flow sensors without an external TDC chip, reducing BOM cost. The integrated RTCC with dedicated 32 kHz crystal drive keeps accurate time-stamped metering logs while drawing microamp-level standby current, and the 1 KB EEPROM stores calibration coefficients that survive battery replacement. The 64-pin TQFP package supports both single-phase and three-phase meter PCB layouts.
Recomendado
Embedded HMI Display
The PIC18F67K22-I/PT suits embedded HMI displays that need to drive small character/graphic LCDs alongside touch input. Through its hardware SPI running at up to 16 MHz Fosc/4, the MCU refreshes 128x64 graphical LCDs and OLED modules without DMA, leaving CPU bandwidth for menu logic and communication. The 128 KB Flash stores full UTF-8 font tables and multilingual menu structures, while the 53 I/O lines handle display backlight, key matrix, and rotary encoder inputs. The wide voltage range permits direct connection to both 3.3V OLED modules and 5V character LCDs.
Recomendado
Automotive Body Electronics
For automotive body electronics, the PIC18F67K22-I/PT provides CAN/LIN-friendly peripherals at industrial temperature grade, suitable for non-safety body control modules. Through its EUSART with LIN 2.1 support and hardware CRC, the MCU interfaces directly with LIN slaves (window modules, mirror controllers, ambient lighting) without an external transceiver logic. The 12-bit ADC reads thermistor-based climate sensors and switch contact positions, while PWM modules drive LED lighting and small motor loads. For under-hood or extended-temperature automotive nodes, drop in the PIC18F67K22-E/PT (-40C to +125C).
Recomendado
USB Device Peripheral
The PIC18F67K22-I/PT can serve as a USB device peripheral when paired with an external USB transceiver such as the MCP2200 or MCP2221, or as a low-speed USB controller for simple HID class products. While the 67K22 lacks an integrated USB PHY (unlike the PIC18F46K22), the EUSART and 53 I/O lines provide ample bandwidth for UART-to-USB bridging, sensor-to-USB gateways, and CDC-class virtual COM ports. The 128 KB Flash comfortably stores USB stacks and vendor class descriptors, and the XLP sleep mode limits suspend-state current to USB spec limits below 2.5 mA.

Notas de projeto
Apply a robust decoupling network on VDD/AVDD: place a 100 nF ceramic capacitor as close as possible to each VDD/AVDD pin pair, plus a shared 10 uF bulk capacitor within 1 cm of the package. Estimated: switching noise at 64 MHz Fosc with 16 MIPS instruction throughput generates high-frequency transients that require low-inductance decoupling paths. For analog ADC accuracy, place a ferrite bead or small inductor between VDD and AVDD to isolate digital switching noise from the analog rail.
Route the ICSP pins (RB6/PGC and RB7/PGD) to a 6-pin header with short, direct traces and no series resistors; Microchip programmers expect direct access. Estimated: trace stubs longer than 25 mm on PGC/PGD risk signal integrity issues at 64 MHz. Keep the crystal traces (OSC1/OSC2) short and symmetric, with the load capacitors within 3 mm of the MCU pins to avoid oscillator startup failures.
Do not confuse the industrial (-I) and extended (-E) temperature grades when ordering - the E grade costs more and is unnecessary for indoor industrial panels. Estimated: MCLR requires a 10 kohm pull-up to VDD and a 100 nF capacitor for reliable reset behaviour; omitting these components causes intermittent power-on-reset failures in noisy environments. Always configure the Configuration Words (CONFIG1H, CONFIG2L) for the proper oscillator mode and BOR threshold before code execution, otherwise the MCU may lock out further ICSP programming.
