MPN: PIC18F87K22T-I/PTRSL ✓ فعالPIC18F87K22T-I/PTRSL نمای کلی
An 8-bit PIC microcontroller is a Harvard-architecture RISC device that executes one instruction every four oscillator cycles (200 ns at 20 MHz instruction clock) with separate program and data buses. Within the broader taxonomy, a microcontroller sits under MCU -> microprocessor -> semiconductor -> IC, and is used wherever embedded intelligence, peripheral control, or low-power standby operation is needed. The XLP family adds deep sleep modes in the nA-to-uA range, enabling battery-powered products to last years on a single cell.
Key features include a 64 MHz maximum CPU clock (16 MIPS), 70 digital I/O pins, a 12-bit A/D converter with up to 16 input channels, multiple capture/compare/PWM modules, two MSSP (SPI/I2C) ports, two USART modules, and the Charge Time Measurement Unit (CTMU) for capacitive touch and accurate time measurement. The 80-pin TQFP provides ample I/O for human-interface and motor-control designs, and the I-grade (-40C to +85C) operating range covers most indoor and industrial environments.
Architecturally, the PIC18F87K22 uses an enhanced RISC core with hardware multiply, a 31-level deep hardware stack, and a priority-controlled interrupt controller. nanoWart XLP technology implements deep sleep currents measured in tens of nanoamps, with multiple wake sources including RTCC, interrupts, and the watchdog timer. The on-chip CTMU can measure capacitance, temperature, and time with high accuracy for touch, flow, and metering applications.
Typical applications include industrial HMI panels, capacitive touch keypads, battery-powered sensor nodes with LCD or segment displays, motor and stepper control, USB device bridges, and automotive body controllers. The combination of 128 KB Flash, 4 KB RAM, and rich peripherals makes it a good fit for mid-range embedded products with graphical or networked user interfaces.
When designing with this MCU, allocate at least 0.1 uF decoupling on every VDD/VSS pair, follow Microchip's Emulation Header layout guidelines for debug, and use the ICD 3 or PICkit 4 programmer for development. The 'T' suffix in the MPN indicates tape-and-reel packaging, and the '-I' suffix denotes the industrial temperature grade (-40C to +85C).

کاربردهای معمول
PIC18F87K22T-I/PTRSL مناسب است برای 6 کاربردs: Industrial HMI Control Panels, Capacitive Touch Keypads, Battery-Powered Sensor Nodes with LCD, Motor and Stepper Control, USB Device Bridges and Converters, Automotive Body and Climate Controllers.
Industrial HMI Control Panels
The PIC18F87K22T-I/PTRSL's 80-pin TQFP exposes 70 I/O lines and drives segmented LCD, character LCD, or small graphical TFT panels via parallel interface. With 128 KB Flash and 4 KB RAM, it runs multi-page menus, button debouncing, and modbus or CANopen master stacks comfortably. Industrial-grade -40C to +85C operation and nanoWatt XLP standby enable always-on key response without excessive cabinet heat rise.

Capacitive Touch Keypads
The on-chip Charge Time Measurement Unit (CTMU) on the PIC18F87K22T-I/PTRSL measures capacitance with sub-pF resolution, enabling robust touch sliders, wheels, and button matrices without external analog ICs. Combined with XLP deep sleep at tens of nA, a battery-powered door lock can stay in standby for years while waking instantly on touch. The 12-bit ADC and CTMU share the I/O pins used for touch, so no extra components are required beyond the sensor pad and ground pour.

Battery-Powered Sensor Nodes with LCD
nanoWart XLP sleep modes and the on-chip RTCC on the PIC18F87K22T-I/PTRSL enable multi-year battery operation in remote sensor applications. The 4 KB RAM buffers sensor data between sleep cycles, and 1 KB EEPROM stores calibration constants that survive deep power-down. With two USARTs and two MSSP ports, it bridges I2C sensors and SPI radios while displaying readings on an external character LCD.

Motor and Stepper Control
The PIC18F87K22T-I/PTRSL provides multiple CCP/ECCP modules generating complementary PWM outputs suitable for driving H-bridge and three-phase motor stages. Its 16 MIPS throughput runs field-oriented control loops at adequate update rates for small BLDC pumps and stepper drivers. The 12-bit ADC samples motor currents at tens of kHz, while the high-pin-count TQFP exposes encoder and limit-switch inputs without multiplexing.
پیشنهادی
USB Device Bridges and Converters
Using Microchip's USB stack on the PIC18F87K22T-I/PTRSL, the MCU can implement USB CDC, HID, or vendor-class bridges between a PC and serial or SPI peripherals. The 64 MHz core easily handles full-speed USB 2.0 packet scheduling and bulk transfers, while 4 KB of RAM buffers endpoint data. The 80-pin TQFP provides enough I/O to drive status LEDs, buttons, and the upstream/downstream serial links concurrently.
پیشنهادی
Automotive Body and Climate Controllers
In the extended-temperature PIC18F87K22 family, the PIC18F87K22T-I/PTRSL handles climate control and lighting loads in automotive body modules with 70 robust I/O pins driving relays and LED drivers. Its 12-bit ADC reads thermistors and potentiometers accurately, and the CTMU can replace mechanical switches with capacitive proximity sensors. The wide supply range (4.2-5.5 V) tolerates automotive load-dump transients with proper external protection.

یادداشت‌های طراحی
Place a 0.1 uF ceramic decoupling capacitor on each VDD/VSS pair (pins 12/13, 32/33, 76/77) within 5 mm of the package. Add a bulk 10 uF tantalum or ceramic at the MCU power pin. For battery applications use the nanoWatt XLP Sleep and Deep Sleep modes with RTCC wake-up to reduce average current to single-digit microamps during idle periods.
Keep the 16 MHz crystal (or external clock) traces short and symmetric, with the load capacitors placed within 3 mm of OSC1/OSC2. Route analog and digital grounds separately and join at a single point near the AVDD/AVSS pins (58/59). Avoid running noisy PWM traces parallel to ADC input traces, and place the CTMU touch sensing electrodes on the same layer as the MCU with a solid ground pour beneath.
Do not leave the MCLR pin floating; tie it to VDD through a 10 kohm resistor with a 100 nF capacitor to VSS for in-circuit serial programming. The RB6/PGC and RB7/PGD lines must not be pulled low at power-on or programming will be blocked. Always configure the CONFIG registers (oscillator, watchdog, brown-out, low-voltage programming) explicitly in source code rather than relying on defaults to avoid spurious resets.
For high-speed SPI peripherals above 8 MHz, add 33 ohm series resistors at the SDO output to dampen ringing, and keep clock traces less than 50 mm long on FR-4. I2C buses require 4.7 kohm pull-ups to VDD for 400 kHz operation. When using the Parallel Master Port (PMP) to drive external LCD or memory, add 22 ohm series resistors on all PMP data and control lines.
