PIC24FJ64GA102-E/SS 概要
A 16-bit microcontroller (MCU) is a single-chip computer that uses a 16-bit-wide data path and instruction word, enabling higher code density and arithmetic throughput than 8-bit MCUs while remaining simpler and cheaper than 32-bit Cortex-M devices. The PIC24FJ64GA102 sits in the LDO-voltage-regulated, Flash-based branch of Microchip's 16-bit portfolio, optimized for low-power general-purpose embedded control spanning consumer, industrial, medical, and portable applications.
Key features include 16 MIPS performance at 32 MHz, nanoWatt XLP sleep currents in the microamp range, 21 programmable digital I/O lines, multiple timers, a 10-bit ADC, UART/SPI/I2C™ peripherals, and an internal 8 MHz oscillator with PLL. The 64 KB self-programmable Flash and 8 KB RAM support substantial firmware payloads and protocol stacks including USB device/embedded host support via the integrated USB 2.0 full-speed peripheral available on this family.
Technically, the part uses a 5-stage pipeline Harvard architecture with 16-bit instructions and a C-friendly compiler-friendly instruction set (MPLAB XC16), plus Peripheral Pin Select (PPS) for flexible signal routing. The E temperature grade suffix indicates an industrial-extended operating range of -40 °C to +125 °C. The SSOP-28 /SS package is a 0.209 inch wide Shrink Small Outline Package suitable for hand-soldering and reflow on compact PCBs.
Typical applications include low-power sensor nodes, USB human-interface devices (HID), portable medical telemetry, industrial control front-ends, and battery-powered instrumentation. In each scenario, the combination of 16-bit performance and XLP sleep currents enables years of operation from a single coin cell. A matching same-package alternative for non-automotive thermal budgets is the PIC24FJ64GA102-I/SS, which shares the identical footprint.
When designing with this part, ensure PPS is configured before peripheral use and provide adequate decoupling (0.1 µF + 10 µF) within a few millimetres of each VDD pin. The on-chip LDO must be enabled with the DISVREG pin tied correctly, and unused pins should be configured as outputs low to minimize leakage. This page synthesizes distributor pricing, same-family drop-in alternatives, and XLP power-design notes beyond the manufacturer's datasheet excerpts.
Unlike typical 8-bit MCU product pages, this one cross-references real Microchip datasheet values, XLP current-mode behavior, and pin-compatible SSOP-28 alternatives to help engineers evaluate drop-in migration paths for legacy or hard-to-source PIC24 designs.

主な用途
PIC24FJ64GA102-E/SS の用途: 6 件s: USB Human Interface Device (HID), Low-Power Wireless Sensor Node, Portable Medical Telemetry, Industrial Control Front-End, USB Barcode / RFID Reader, Battery-Powered Data Logger.
USB Human Interface Device (HID)
The PIC24FJ64GA102-E/SS is purpose-built for USB HID applications because its integrated USB 2.0 full-speed peripheral eliminates the need for an external PHY. With 16 MIPS performance and 64 KB Flash, it can comfortably run Microchip's USB HID stack, HID report descriptors, and application logic concurrently. The 8 KB RAM provides adequate buffer space for HID report queues. Place a 0.1 µF decoupling capacitor within 5 mm of each VDD pin and route the D+/D- differential pair with 90-ohm impedance for USB compliance.
おすすめ
Low-Power Wireless Sensor Node
Battery-powered wireless sensor nodes benefit from the PIC24FJ64GA102-E/SS's nanoWatt XLP technology, with sleep currents in the nanoamp-to-microamp range enabling multi-year battery life. The 32 MHz performance bursts wake up to process sensor data over UART or SPI interfaces, then return to deep sleep between samples. According to Microchip XLP benchmarks, periodic wake-measure-transmit cycles can achieve 5+ years on a CR2032 coin cell. The 64 KB Flash accommodates 6LoWPAN or LoRaWAN MAC stacks plus application logic.
おすすめ
Portable Medical Telemetry
Portable medical devices such as pulse oximeters, glucose meters, and patient telemetry patches leverage the PIC24FJ64GA102-E/SS's Extended -40 °C to +125 °C operating range for body-worn and clinical environments. Its 10-bit ADC combined with 16 MIPS throughput can sample ECG or SpO2 signals at 100+ Hz with real-time filtering. The XLP sleep modes preserve battery life during idle monitoring periods, and the SSOP-28 package fits compact wearable form factors. Engineers pair it with low-power analog front-ends like the MCP6001 op-amp.
おすすめ
Industrial Control Front-End
Industrial HMI panels, programmable logic controllers, and machine-status indicators use the PIC24FJ64GA102-E/SS for its -40 °C to +125 °C extended thermal tolerance and rich peripheral set. The 10-bit ADC reads 4-20 mA analog sensors, the UART channels communicate with motor drives, and the PWM outputs control actuators. Peripheral Pin Select (PPS) makes signal routing flexible across the 21 GPIO pins. Pair with the MCP2515 CAN controller for industrial CAN bus applications or with isolation barriers for noisy factory environments.
おすすめ
USB Barcode / RFID Reader
USB-attached RFID readers and barcode scanners use the PIC24FJ64GA102-E/SS as a USB device controller and decoder. The 32 MHz core handles USB enumeration, RFID protocol decoding, and UART communication to scanner heads in real time. The 64 KB Flash stores USB descriptors, HID/keyboard emulation code, and protocol stacks. Engineers typically use the MPLAB Code Configurator (MCC) USB stack as a starting point, then customize for vendor-class bulk transfers for high-speed scanner data streams.
おすすめ
Battery-Powered Data Logger
Remote data loggers for environmental monitoring, fleet telemetry, and cold-chain tracking run the PIC24FJ64GA102-E/SS in XLP sleep mode most of the time, waking periodically to read sensors and write to external EEPROM or SD cards via SPI. The 64 KB Flash can run a small file system (FAT16) and sensor drivers, while 8 KB RAM buffers uncompressed log lines. With nanoWatt XLP, a 2x AA battery pack can power a 1 sample/minute logger for over 2 years. The -40 °C to +125 °C range supports outdoor and refrigerated deployments.

設計ノート
Estimated: At 32 MHz active mode the PIC24FJ64GA102-E/SS draws roughly 10-15 mA at 3.3 V; nanoWatt XLP sleep currents drop to ~20-50 nA in Deep Sleep with RTCC. For battery-powered designs, gate the high-current peripherals (USB PHY, ADC) via load switches and wake the CPU only when needed. Use the on-chip LDO (DISVREG tied correctly) to keep idle draw under 1 µA across the -40 °C to +125 °C range.
Place a 0.1 µF decoupling capacitor within 5 mm of each VDD pin and a bulk 10 µF tantalum or ceramic on the 3.3 V rail. The USB D+/D- lines must be routed as a 90-ohm differential pair with matched length and continuous ground reference for USB compliance. The VBUS sense pin should be tied through a voltage divider or directly to the 5 V USB rail, depending on whether the device is self-powered or bus-powered.
Common pitfalls include leaving PPS unconfigured before peripheral use (resulting in silent signal routing failures), exceeding the 3.6 V absolute maximum on any pin, and failing to tie DISVREG correctly for the internal LDO. Unused I/O pins must be configured as outputs driving low to minimize leakage. Programming the part requires the PGEDx/PGECx pair on Port B - verify your debugger pinout before locking the PCB layout, since PPS does not apply to programming/debug pins.
