PIC18F87K22T-I/PT Descripción general
An 8-bit microcontroller (MCU) is a programmable logic device that executes instructions one byte at a time and integrates CPU, memory, and peripherals on a single silicon die. PIC18F-series MCUs (PIC -> Peripheral Interface Controller -> Microchip's 8-bit architecture -> microcontroller family -> embedded computing) extend the baseline PIC16 architecture with an enhanced instruction set, 16-bit wide program memory, and a linear program/data memory map. The K22 sub-family further adds nanoWatt XLP (eXtreme Low Power) Technology with deep-sleep currents well under 1 microampere, positioning the device for battery-constrained applications.
Key features include a maximum CPU clock of 64 MHz delivering up to 16 MIPS (Million Instructions Per Second), a 12-bit A/D converter with up to 30 channels, an integrated Charge Time Measurement Unit (CTMU) for capacitive touch sensing, multiple Enhanced USART, SPI, and I2C peripherals, and a nanoWatt XLP power-management block that supports idle, sleep, and deep-sleep modes. The 80-pin TQFP exposes up to 70 I/O pins and supports external memory interfaces via the Parallel Slave Port and Extended Microcontroller modes, enabling connection to external peripherals or memory-mapped devices.
Architecturally, the PIC18F87K22 employs a Harvard-class modified RISC core with a 16-bit instruction word, an 8-bit data path, hardware multiply, and a programmable instruction set optimized for compiled C code. The internal oscillator, watchdog timer, brown-out reset, and in-circuit debug (ICD) interface collectively reduce external component count and shorten firmware development cycles, which is one reason the family remains popular in industrial control and human-machine interface designs.
Typical applications include industrial control panels, home appliance user interfaces, capacitive touch keypads, sensor hubs, energy-harvesting battery nodes, automotive accessory modules, and USB HID human-interface devices using the PIC18 USB-enabled peripheral extensions. The combination of 128KB Flash (1 Mbit class) and 70 I/O pins makes the part well suited to mid-complexity graphical LCD or segmented display products.
Designers should note that the 80-pin TQFP and 80-pin QFN variants of this part are pin-compatible within their respective packages but NOT interchangeable between packages. Programming is performed via ICSP (In-Circuit Serial Programming) or the ICD interface; production programmers from MPLAB, PICKit, and third-party vendors support the device.

Aplicaciones típicas
PIC18F87K22T-I/PT es adecuado para 6 aplicacións: Industrial Control Panel HMI, Capacitive Touch Keypads, Appliance Front-Panel Controllers, Battery-Powered Sensor Hubs, Automotive Accessory Modules, USB HID Human-Interface Devices.
Industrial Control Panel HMI
The PIC18F87K22T-I/PT is well matched to industrial control panel human-machine interfaces because 128KB Flash and 4KB RAM easily accommodate structured-segment or grayscale graphics libraries, while 70 GPIO drive segmented LCDs, keypads, status LEDs, and rotary encoders without external bus expanders. nanoWalt XLP keeps idle panels under 1 uA for battery-backed operator stations. The 12-bit ADC reads analog sensor inputs (temperature, pressure, current shunt) at 100 ksps, while EUSART/SPI handle Modbus RTU or device-net side-channels. Industrial -40 to +85 C temperature and 5V tolerance match 24V-bus sensor subsystems.
Recomendado
Capacitive Touch Keypads
The PIC18F87K22T-I/PT's on-chip CTMU (Charge Time Measurement Unit) measures small capacitance changes from the touch electrode to mechanical overlay, eliminating the need for a dedicated touch controller. Combined with 128KB Flash, designers can run Microchip's mTouch or third-party capacitive-touch libraries with finite state machine control and surface gesture decoding. The 12-bit ADC tracks ambient noise for self-calibration, while XLP deep-sleep with touch wake-up enables sealed-battery keypads that last 5+ years on a single coin cell, ideal for door locks and appliances.
Recomendado
Appliance Front-Panel Controllers
Home-appliance front panels (washing machines, ovens, induction cooktops) require robust 5V-tolerant I/O for triac/relay control, segmented or TFT display drivers, and reliable motor-control timing. The PIC18F87K22T-I/PT's 70 GPIO drive multi-digit 7-segment or character LCDs without extra logic, while its CCP/ECCP units generate PWM and zero-cross control for AC loads. With 128KB Flash it can host bootloader plus vector graphics plus diagnostics, and the industrial -40 to +85 C range covers under-cabinet thermal environments. nanoWalt XLP keeps idle standby for smart appliances well under 100 uA.
Recomendado
Battery-Powered Sensor Hubs
For battery-driven sensor and IoT edge nodes, the PIC18F87K22T-I/PT's nanoWatt XLP Technology supplies sub-1 uA deep-sleep, RTC, and wake-on-touch via CTMU. The 128KB Flash accommodates Microchip's MPLAB X-generated C runtime plus LoRa, BLE, or sub-GHz radio drivers via SPI. Industrial temperature range plus wide 1.8-5.5V supply support direct attachment to lithium primary cells, energy harvesting inputs, or solar chargers. Up to 30 channels of 12-bit ADC enable multi-modal sensing (temperature, humidity, flow, voltage) per node.
Recomendado
Automotive Accessory Modules
Although not AEC-Q100 qualified, PIC18F87K22T-I/PT's industrial -40 to +85 C range and 5V tolerance make it suitable for non-safety automotive accessories such as interior lighting controllers, configurable door warning chimes, and aftermarket infotainment extenders. The 12-bit ADC reads battery sense, lighting current shunt, and rotary encoder inputs, while EUSART/SPI can connect to CAN transceivers. The 80-pin TQFP is pad-compatible with PIC18F8720/8722/8723 legacy automotive accessory designs, easing second-source procurement.
Recomendado
USB HID Human-Interface Devices
Custom HID peripherals (programmable keypads, studio controllers, instrumentation panel mounts) pair the PIC18F87K22T-I/PT with a USB 2.0 full-speed transceiver via the integrated EUSART/SPI or a host-side interface chip. The 128KB Flash holds the HID descriptor, keymaps, and MACRO/PROFILE firmware. 12-bit ADC enables analog-joystick or pedal-axis reading, while 4KB RAM buffers report frames. The industrial temperature range and wide 1.8-5.5V supply support bus-powered and self-powered designs in the same BOM.

Diferenciadores clave
- Higher CPU clock than legacy F8723 (frente a PIC18F8723-I/PT)
- Larger Flash than PIC18F85K22 (frente a PIC18F85K22T-I/PT)
- nanoWatt XLP technology (frente a PIC18F87J72-I/PT)
Notas de diseño
Estimated: at the maximum 64 MHz CPU clock the PIC18F87K22 family draws roughly 15 mA active (Vdd=5V per datasheet typical values). Switching to 1 MHz via the internal oscillator drops consumption to about 2 mA. For battery applications, enter Sleep (typical <1 uA) and use RTCC, INTx, or PORT change-on-interrupt to wake. Place a 0.1 uF decoupling cap within 5 mm of every Vdd/Vss pair, plus a bulk 10 uF near the Vdd pins, to suppress XLP wake-up voltage ringing.
The 80-TQFP package requires fine-pitch (0.4 mm) fan-out; use 4 mil traces and 8 mil clearances with a 12x12 mm solder-paste stencil that mimics the land pattern. Keep the MCLR/ICSP pins (PGC/PGD on RB6/RB7, MCLR on pin 1) on the top layer or accessible via test pads for in-circuit programming. Route the quartz between OSC1/OSC2 with short traces and guard ground; if the PLL is used, route the PLL bypass capacitor close to the VCAP pin.
When using the CTMU for capacitive touch, isolate the CTMU charge-current pin from high-speed digital signals and route the touch sensor traces over a solid ground pour. For SPI peripherals running above 5 MHz, add 33 ohm series termination at the source pins to control rise-time ringing; keep the SPI clock length-matched to its data lines.
Do not confuse PIC18F87K22 with the similar-sounding PIC18F8722 or PIC18F8723: K22 variants use 64 MHz and nanoWalt XLP, while 8722/8723 use 40 MHz and lack CTMU. The PIC18F87J72 is a different Flash-and-ADC-lesser variant. Confirm the supply-voltage range (1.8 to 5.5 V or 4.2 to 5.5 V depending on frequency) before swapping parts. Unused I/O must be configured as outputs or inputs-with-pull-ups to avoid floating-pin current draw in Sleep.
Información de cumplimiento
RoHS and REACH compliant per Microchip product declaration. Not AEC-Q100 qualified; the standard PIC18F87K22 family is intended for industrial and commercial use rather than automotive safety-critical applications.
