PIC24FJ64GA008-I/PT 概要
A 16-bit PIC microcontroller is a low-power MCU built around a 16-bit modified Harvard architecture. PIC24F devices sit in the middle of Microchip's 8-bit (PIC16/PIC18) and 32-bit (PIC32) portfolio, defining the microcontroller category as programmable computation engine -> embedded MCU -> digital IC -> semiconductor. The wider data path (24-bit instruction word, 16-bit data path) delivers higher throughput than 8-bit MCUs at similar clock rates while retaining low power consumption typical of Flash-based PIC devices.
Key features include 64KB self-programmable Flash with EEPROM emulation, 8KB SRAM, a 16-channel 10-bit ADC with 500ksps conversion rate, five 16-bit timers, two UART modules, two SPI ports, two I2C ports, and a Parallel Master Port. The CTMU peripheral enables touch sensing and capacitive measurement applications. The 80-pin TQFP package offers 69 digital I/O pins plus dedicated analog, communication, and clock pins, suitable for mid-complexity embedded designs.
The PIC24FJ64GA008 uses a pipelined RISC core with hardware multiplier and divider, achieving 16 MIPS performance. The integrated nanoWatt technology provides multiple power-saving modes (idle, sleep, deep sleep) and peripheral clock gating, suitable for battery-powered and energy-harvesting designs.
Typical applications include industrial control panels, home automation gateways, HVAC controllers, sensor hubs, USB device interfaces, graphical user interfaces with PICtail Plus daughter cards, and general-purpose 16-bit embedded systems. The Explorer 16/32 Development Board supports this part via Plug-In Modules (PIMs) for rapid prototyping.
When designing with this part, note that the operating voltage range of 2.0V-3.6V is strict; using 5V will damage the device. Add 0.1uF decoupling capacitors near each VDD/VDDCORE pin pair, and connect all VSS pins to a common ground plane. The internal 8 MHz Fast RC oscillator with PLL can replace an external crystal for cost-sensitive designs, but crystal accuracy is required for USB or CAN timing.

主な用途
PIC24FJ64GA008-I/PT の用途: 7 件s: Industrial Control Panels, Home Automation Gateway, USB Device Peripherals, Capacitive Touch Interfaces, HVAC Climate Controllers, Sensor Hub / Data Logger, Graphical User Interfaces (LCD).
Industrial Control Panels
The PIC24FJ64GA008-I/PT suits industrial control panels thanks to its 69 digital I/O pins and 16-channel 10-bit ADC. Industrial HMI panels typically require multiple key inputs, LED indicators, and analog sensor inputs (temperature, pressure, current) - the 64GA008 handles up to 16 analog inputs at 500 ksps conversion rate, plus PWM outputs for indicator dimming. Its 2.0V-3.6V operation with -40C to +85C industrial temperature range supports factory floor deployment. The integrated USB 2.0 full-speed peripheral enables panel configuration upload and diagnostics logging to a host PC, while the nanoWatt power-saving modes reduce idle power in panels with always-on standby requirements.
おすすめ
Home Automation Gateway
The PIC24FJ64GA008-I/PT works well as a home automation gateway controller because of its multiple communication peripherals - 2 UART, 2 SPI, and 2 I2C ports allow simultaneous connection to Wi-Fi modules (via UART), Zigbee/Z-Wave radios (via UART), and local sensors (via I2C/SPI). Its 64KB Flash accommodates protocol stacks like MQTT and Modbus, while 8KB SRAM handles message buffering. The CTMU peripheral supports capacitive touch inputs on wall-mounted control panels. Operating from 2.0V-3.6V, the 64GA008 can run from a regulated 3.3V supply common in home automation hardware, and the -40C to +85C industrial temperature range covers residential and light-industrial installations.
おすすめ
USB Device Peripherals
The PIC24FJ64GA008-I/PT's integrated USB 2.0 full-speed peripheral with on-chip transceiver makes it a strong choice for USB HID devices like keyboards, mice, game controllers, and custom USB peripherals. The internal PLL can derive the required 48 MHz USB clock from a 4 MHz crystal, eliminating external clock components. The 64KB Flash and 8KB SRAM comfortably fit USB HID class drivers plus application logic, while the 16 MIPS CPU ensures responsive USB polling. Operating voltage is strictly 2.0V-3.6V, so level shifting may be needed for 5V USB hosts. For USB OTG or host functionality, the PIC24FJ64GB108-I/PT drop-in alternative in the same TQFP package adds OTG support.
おすすめ
Capacitive Touch Interfaces
The PIC24FJ64GA008-I/PT includes Microchip's CTMU (Charge Time Measurement Unit) peripheral specifically designed for capacitive touch sensing - this enables touch buttons, sliders, and proximity sensors without external touch ICs. The CTMU generates precisely controlled current sources used in conjunction with the ADC to measure capacitance changes caused by finger touches. With 16 ADC inputs available, the 64GA008 supports up to 16 touch electrodes directly, expandable via I/O expanders. The 16 MIPS CPU can poll all touch electrodes at a 100Hz update rate, suitable for appliance control panels, LED dimmer switches, and consumer electronics touch UIs where mechanical buttons are undesirable.
おすすめ
HVAC Climate Controllers
The PIC24FJ64GA008-I/PT suits HVAC climate controller designs with 16 analog inputs for temperature sensors (NTC thermistors, analog ICs like MCP9700), 5 timers for PWM-driven fan and damper control, and 64KB Flash for PID control loops and scheduling firmware. The nanoWatt power-saving modes drop quiescent current to microamps during idle, meeting Energy Star standby requirements for thermostats. The 16 MIPS CPU runs multi-zone temperature averaging algorithms in real time. Operating voltage of 2.0V-3.6V with -40C to +85C industrial temperature range supports installation near furnaces, air handlers, and outdoor units where temperatures swing widely.
おすすめ
Sensor Hub / Data Logger
The PIC24FJ64GA008-I/PT works as a multi-sensor hub and data logger with 2 I2C and 2 SPI ports enabling simultaneous connections to multiple sensors (accelerometers, gyros, magnetometers, environmental sensors, pressure sensors). Its 8KB SRAM buffers sensor data between writes, and the USB peripheral enables fast offload of logged data to a host PC. The 16-channel 10-bit ADC at 500 ksps conversion rate handles analog sensor inputs like strain gauges and thermocouples via signal conditioning. Real-time clock with calendar and battery backup support (via RTCC peripheral with external 32.768 kHz crystal) timestamps all logged entries. For larger logs, external SPI Flash like SST25VF016B extends storage to MB scale.
おすすめ
Graphical User Interfaces (LCD)
The PIC24FJ64GA008-I/PT includes a Parallel Master Port (PMP) for interfacing with parallel LCDs and graphical displays, plus 64KB Flash for GLCD graphics libraries and 8KB SRAM for framebuffer on smaller displays. The PMP peripheral directly drives character LCDs, TFT displays with parallel interfaces, and OLED panels with 8-bit or 16-bit data bus. With 69 digital I/O available, the 64GA008 drives the display while leaving pins for touch input (via CTMU), keypad matrix, and communication interfaces. The Explorer 16/32 Development Board with PICtail Plus daughter cards accelerates prototyping of GUI-based products. Operating voltage 2.0V-3.6V suits modern TFT/OLED panels with on-chip charge pumps.

設計ノート
Place a 10uF bulk capacitor and 0.1uF decoupling capacitor near each VDD/VDDCORE pin pair. The PIC24FJ64GA008-I/PT has multiple VDD/VSS pairs (VDD, VDDCORE, AVDD, AVSS) that all require individual decoupling. Tie the ENVREG pin to VDD via a 10uF capacitor to enable the internal 2.5V core voltage regulator; leaving ENVREG floating disables internal regulation and requires external 2.5V supply.
Route the 32.768 kHz crystal traces as short and symmetric as possible, with a ground guard ring, to minimize noise coupling into the low-amplitude oscillator. The main 4-32 MHz crystal traces have similar requirements. Place the crystal within 5mm of the OSCI/OSCO pins and avoid routing digital signals underneath or near the crystal traces.
For USB applications, the D+/D- traces must be 90 ohm differential impedance matched, length-matched within 1mm, and kept short. Add a 90 ohm common-mode choke near the connector, and ensure the USB cable shield connects to chassis ground via a ferrite bead to reduce EMI. Route USB traces on the top layer over a continuous ground plane on the adjacent layer.
Do not apply 5V to VDD or any I/O pin - the absolute maximum is 3.6V and 5V will damage the device. Connect all VSS pins to a common ground, even unused ones - floating VSS pins can cause programming failures and erratic operation. The MCLR pin requires a 10k pull-up to VDD for normal operation; do not leave it floating. Use the PPS (Peripheral Pin Select) feature to remap peripherals to alternate pins, but verify the PPS lock bits are properly configured before reset to prevent accidental remapping.
