PIC18F64J11-I/PT 概要
A PIC18 microcontroller is an 8-bit Harvard-architecture MCU from Microchip's enhanced mid-range family, used in cost-sensitive embedded systems. It sits within the broader taxonomy: microcontroller (MCU) -> embedded controller -> semiconductor -> integrated circuit. The PIC18 family offers higher performance (up to 16 MIPS) than PIC16 parts and simpler programming than PIC24/dsPIC, making it a workhorse for industrial, automotive, and consumer applications.
Key features of the PIC18F64J11 include nanoWatt Technology for ultra-low sleep current (sub-uA), an internal 8MHz oscillator that eliminates the need for an external crystal in many designs, 16KB of self-programmable Flash, 1KB of RAM, a 10-bit ADC, multiple timers, and Enhanced Capture/Compare/PWM modules. Communication peripherals include I2C, SPI, and Enhanced USART interfaces, and a parallel port for external memory or graphics interfacing.
The PIC18F64J11 family uses a modified Harvard core with a 16-bit instruction word, single-cycle hardware multiply, and a 31-level hardware stack. The nanoWatt XLP power management offers several idle/sleep modes, internal voltage regulator, and ultra-low-power Real-Time Clock calendar operation, allowing battery-powered designs that can sleep at sub-uA currents while retaining RAM and RTCC operation.
Typical applications include industrial data loggers, USB peripherals (with external transceiver), sensor signal conditioning, motor control (low-end), environmental monitoring, and cost-sensitive consumer electronics. It is also widely used in educational environments for embedded systems curriculum.
When designing with this device, allocate PCB real estate for the 64-pin TQFP and provide proper decoupling: a 100nF ceramic cap within 3mm of each power pin and a bulk 10uF tantalum on VDD. For low-power designs, leverage the nanoWatt XLP sleep modes and the internal 31kHz RTCC oscillator to retain RAM while consuming <1uA.

主な用途
PIC18F64J11-I/PT の用途: 7 件s: Industrial Data Loggers, USB HID Peripherals, Sensor Signal Conditioning Hubs, Educational Embedded Platforms, Low-Power Battery IoT Nodes, HVAC Control Panels, Motor Control (Low-End BLDC / Stepper).
Industrial Data Loggers
The PIC18F64J11-I/PT fits industrial data loggers via its 54 digital I/O pins, 10-bit ADC, and 16KB Flash for FAT-style file system code. With nanoWatt XLP technology consuming <1uA in sleep, battery-powered loggers can run for years on a single AA cell while waking periodically to record sensor data. The internal 8MHz oscillator eliminates external crystal cost, and 1KB SRAM is sufficient for buffering hundreds of samples between writes. Real-world deployment examples include temperature/humidity monitors in cold-chain shipping and predictive-maintenance sensors on factory equipment.
おすすめ
USB HID Peripherals
The PIC18F64J11-I/PT is widely used in USB Human Interface Device designs (keyboards, mice, game controllers) when paired with an external USB transceiver such as the MCP2200 or FT232. Its 10 MIPS throughput comfortably handles USB 1.1 low-speed HID class descriptors and HID report parsing in software stack. The 16KB Flash holds the USB stack plus application code, and 54 GPIO pins support matrix-scanned keypads up to 8x8. The 10-bit ADC can read analog joysticks or potentiometers, while nanoWatt XLP enables bus-powered devices with strict suspend-current requirements.
おすすめ
Sensor Signal Conditioning Hubs
The PIC18F64J11-I/PT is ideal as a sensor-hub MCU aggregating multiple analog and digital sensors via I2C/SPI. Its 10-bit ADC can sample up to 16 channels of analog sensors (thermistors, strain gauges, light sensors) while its hardware I2C/SPI masters read digital MEMS sensors. The 16KB Flash fits Microchip's MPLAB X generated peripheral libraries plus application logic. The 64-TQFP package exposes enough GPIO to drive status LEDs, keypad inputs, and buzzer outputs. Typical deployments include HVAC control panels, weather stations, and multi-sensor IoT edge nodes.
おすすめ
Educational Embedded Platforms
Universities and training academies use the PIC18F64J11-I/PT in embedded systems courses due to its accessible C compiler (XC8), free MPLAB X IDE, and rich peripheral set. The 64-TQFP package is breadboard-compatible via breakout boards, allowing students to learn GPIO, timers, ADC, and serial communications hands-on. The PIC18 instruction set is documented in 396 pages of datasheet - ideal teaching material. The 16KB Flash supports real C projects including state machines, RTOS-lite kernels, and communication stacks, preparing students for industry PIC24/dsPIC/PIC32 work.
おすすめ
Low-Power Battery IoT Nodes
The PIC18F64J11-I/PT powers battery-operated IoT edge devices via its nanoWatt XLP sleep current of <100nA with RTCC retention. The internal 31kHz RTCC oscillator keeps real-time wake-up scheduling accurate without external 32.768kHz crystal, reducing BOM cost. The 16KB Flash holds wireless-stack proxy code (when paired with RN2483 LoRa or nRF24L01 transceivers), and 54 GPIO supports multiple sensor interfaces. The 10-bit ADC is sufficient for battery voltage monitoring - critical for predictive low-battery alerts in remote deployments like agricultural sensors and asset trackers.
おすすめ
HVAC Control Panels
The PIC18F64J11-I/PT suits HVAC control panels in residential and light-commercial thermostats, providing 10-bit ADC for thermistor temperature sensing, PWM outputs for triac-driven fan control, and UART for communication with HVAC indoor units. The 16KB Flash fits custom UI state machines plus Modbus/ASCII protocols, while 1KB RAM is ample for menu and scheduling buffers. The industrial -40C to +85C temperature rating matches HVAC equipment specifications, and the 64-TQFP package exposes enough GPIO for LCD interfaces, keypads, and relay drivers.
おすすめ
Motor Control (Low-End BLDC / Stepper)
The PIC18F64J11-I/PT drives low-end BLDC and stepper motors via its Enhanced CCP (ECCP) modules producing complementary PWM with programmable dead-time. The 10-bit ADC samples back-EMF or current-sense shunt resistors for sensorless commutation on small BLDC fans and pumps. The 40MHz / 10 MIPS throughput handles 20kHz PWM switching frequency while leaving cycles for serial telemetry. 54 GPIO allows multi-axis control of 2-3 stepper axes. Typical applications include small appliance motors, 3D printer controllers, and CNC auxiliary axes.

主な差別化要因

- Internal 8MHz oscillator eliminates external crystal （vs PIC18F46K22-I/PT)

設計ノート
Estimated: At 40MHz and VDD=5V, the PIC18F64J11-I/PT core draws approximately 15mA typical; in sleep mode with RTCC active, current drops to <1uA per the nanoWatt XLP spec. Place a 100nF ceramic decoupling capacitor within 3mm of each VDD pin and a bulk 10uF tantalum on the main VDD rail. For battery designs, use the internal 31kHz RTCC oscillator to keep time during deep sleep without an external crystal.
The 64-TQFP package has 0.5mm pitch pads requiring careful PCB layout. Use 0.25mm trace width with 0.15mm clearance to fit traces between pads. Provide a continuous ground plane under the IC and stitch vias around the perimeter to suppress EMI. Route the MCLR pin through a 10k pull-up to VDD and a 100nF cap to ground for clean reset behavior - never leave MCLR floating.
Common pitfalls when designing with the PIC18F64J11-I/PT: (1) The I/O pin voltage is limited to VDD - do not apply 5V signals when running on 3.3V via LF variant. (2) The configuration bits must be set correctly for oscillator selection - using the wrong config can lock the device until ICSP recovery. (3) The ADC acquisition time must be programmed per the datasheet, or readings will be inaccurate. (4) When using ICSP, isolate PGC/PGD from application circuitry to avoid programming conflicts.
The 64-TQFP at 40MHz produces moderate EMI. To minimize radiated emissions: (1) keep clock traces short and ground-stitched; (2) use a 4-layer PCB with dedicated ground and power planes; (3) place a ferrite bead on the VDD supply line if the application must meet FCC/CE Class B; (4) for high-current GPIO switching, add 100-ohm series resistors to dampen ringing. The internal 8MHz oscillator avoids the EMI of external crystals.
