PIC24FJ64GA110-E/PT 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), volatile data memory (RAM), and a rich set of peripheral blocks on one die. PIC24F devices sit in Microchip's 16-bit MCU portfolio, positioned between 8-bit PIC16/PIC18 parts and 32-bit PIC32 parts. They are used in applications that need more computational headroom than 8-bit cores can deliver while retaining low-power characteristics and a deterministic interrupt model. The PIC24FJ family further adds peripherals such as RTCC, Parallel Master Port, and multiple serial interfaces, broadening use cases into human-machine interfaces and connectivity products.
The PIC24FJ64GA110-E/PT integrates 64 KB (22K x 24) Flash and 16 KB RAM, 85 general-purpose I/O pins, three I2C, three SPI, and four UART serial interfaces, and 23 independent timers including a Real-Time Clock/Calendar and a 16-bit timer/counter set. The 12-bit A/D converter provides up to 16 channels with 500 ksps conversion rate, while a 10-bit DAC and multiple analog comparators support mixed-signal designs. NanoWatt technology delivers a standby current under 100 nA, enabling battery-powered and energy-harvesting products.
The architecture pairs a 16-bit data path with a 24-bit instruction word, supporting C and assembly development through MPLAB X IDE and MPLAB XC16 compiler. With its 85 I/O count and abundant peripherals, this MCU targets industrial automation controllers, medical patient monitors, automotive body and HMI subsystems, and low-power connected sensor nodes. The 100-TQFP (12x12 mm) package provides a low-profile surface-mount footprint compatible with standard PCB assembly lines.
Consider the wide I/O count and 16 KB RAM when selecting this part. Designs requiring more Flash should step up to the PIC24FJ128 family, while designs needing USB-OTG or CAN should look at the PIC24FJ64GB/GC variants. The -E temperature suffix indicates an extended -40C to +125C operating range, distinct from the -I (-40C to +85C) suffix.

主な用途
PIC24FJ64GA110-E/PT の用途: 6 件s: Industrial Automation Controller, Medical Patient Monitoring, Automotive Body and HMI Subsystems, Low-Power Connected Sensor Node, Consumer Audio and Display Interface, Building Automation and HVAC.
Industrial Automation Controller
The PIC24FJ64GA110-E/PT is well-suited for industrial PLC and process-control submodules because its 64 KB Flash and 16 KB RAM support state-machine logic plus a TFT/HMI data buffer, while the 12-bit ADC with 16 channels handles multi-loop analog sensor reading. The 85 I/O and 23 timers drive parallel I/O modules and PWM outputs simultaneously. NanoWatt standby under 100 nA allows battery-backed controllers to ride out power events without data loss. Compared to 8-bit PIC16/PIC18 parts, the 16 MIPS throughput and 16-bit math enable DSP-style control algorithms (PID, field-oriented motor control) directly in firmware.
おすすめ
Medical Patient Monitoring
Medical bedside monitors and ambulatory devices use the PIC24FJ64GA110-E/PT for signal processing thanks to its 16 MIPS performance and 16 KB RAM, which handle ECG/EEG filter pipelines and 16-channel analog front-end scanning. The 12-bit 500 ksps ADC captures biosensor waveforms at sufficient sample rate, while three SPI buses drive simultaneous DAC, LCD, and radio subsystems. The extended -40C to +125C operating range covers body-worn and clinical environments. The 100-TQFP package is easy to reflow on FR-4 medical-grade PCBs.
おすすめ
Automotive Body and HMI Subsystems
In automotive body controllers, HVAC panels, and mirror/lighting modules the PIC24FJ64GA110-E/PT provides the I/O count and serial bandwidth needed to drive displays, keypads, and LIN/CAN-compatible UART links. Four UARTs handle LIN bus masters and slaves simultaneously, while three SPI ports run display controllers, stepper drivers, and touch sensors. The extended -40C to +125C grade and NanoWatt standby current (<100 nA) suit parking-lot current budgets in modern vehicles. Designers port code from PIC24FJ128 family members by recompiling without layout changes due to identical 100-TQFP footprint.
おすすめ
Low-Power Connected Sensor Node
Battery-powered IoT sensor nodes benefit from the PIC24FJ64GA110-E/PT NanoWatt technology standby current under 100 nA, allowing multi-year life on a single CR2032 cell. The 64 KB Flash holds ZigBee/BLE/LoRa application stacks, while 16 KB RAM buffers sensor telemetry bursts. Three I2C buses read multiple environmental sensors, three SPI drives an RF front-end, and four UARTs handle debug and configuration channels. The 12-bit ADC supports direct thermistor and battery-voltage monitoring without an external ADC.
おすすめ
Consumer Audio and Display Interface
Audio DAC/amplifier front panels and HMI-rich consumer appliances use the PIC24FJ64GA110-E/PT to drive TFT displays and button/keyboard matrices. The 23 timers generate PWM for backlight, buzzer, and LED feedback, while the 16 KB RAM holds double-buffered frame data. The 85 I/O supports capacitive touch sliders and rotary encoders through the parallel master port. The 32 MHz CPU delivers smooth 16-bit DSP filtering of microphone input for voice-command appliances.
おすすめ
Building Automation and HVAC
Building automation controllers, fan-coil units, and VAV box regulators use the PIC24FJ64GA110-E/PT for its mix of 12-bit ADC inputs (temperature/pressure transducers) and multiple UART ports for BACnet/Modbus slaves over RS-485. The 85 I/O drives triac-fired outputs, isolation relays, and 7-segment/HMI displays simultaneously. NanoWatt technology keeps idle power low in always-on wall controllers. The extended temperature range supports unheated equipment rooms and rooftop installations.

設計ノート
Take advantage of NanoWatt sleep modes: the PIC24FJ64GA110-E/PT draws under 100 nA in deep-sleep with RTCC running. Configure all unused peripherals to idle or off and drive I/O pins to a defined state before sleep to avoid parasitic current paths. For battery-backed designs, gate the rest of the board with a high-side load switch controlled by a wake-capable I/O pin to achieve system-level current under 1 uA.
Decouple VDD/VSS pairs with 100 nF ceramic capacitors placed within 3 mm of each supply pin; add a single 10 uF bulk capacitor near the device. Keep the analog VDD/AVSS pair isolated with its own ferrite bead from noisy digital rails to preserve 12-bit ADC performance. Route the 32 MHz crystal traces short and symmetrical, with the load capacitors placed adjacent to the oscillator pins and a guard ring tied to analog ground.
Do not assume the MCLR pin can be left floating - the datasheet requires an external pull-up to VDD because MCLR is an active-low reset. Configure unused I/O as outputs driving low, not as inputs, to prevent shoot-through. When migrating code from PIC24FJ128 to PIC24FJ64 variants, watch Flash page size and Configuration Word settings because erasing pages larger than your code section leaves stale bytes unless you use the proper erase sequence.
Long parallel-bus traces to the PMP/PMP-E pins should be impedance-controlled with series damping resistors near the MCU to reduce ringing on display or memory buses. When using SPI at the maximum peripheral clock, add a 33 ohm series resistor at the SCK output and keep trace lengths under 50 mm to avoid reflections that cause CRC errors with SD card and LCD peripherals.
