PIC24FJ64GB110T-I/PF 概要
A 16-bit microcontroller is a class of embedded processor that uses a 16-bit-wide data path, register file, and ALU - sitting architecturally between 8-bit MCUs (PIC16, AVR) and 32-bit Cortex-M parts. Within the MCU hierarchy it belongs to the PIC24F -> PIC24 -> 16-bit MCU -> microcontroller -> embedded processor -> semiconductor lineage. The "FJ" prefix denotes the Flash-based, low-power family; the "GB" infix signals integrated USB OTG; and "110" is the 100-pin pin-count and 64 KB Flash code member of that sub-family.
Key features include 64 KB Flash, 16 KB RAM, an 8 MHz internal oscillator with 4x PLL (giving the 32 MHz CPU clock), a 17-bit x 17-bit single-cycle hardware multiplier, a 16-bit hardware divider, and a 16-bit working register array that the C compiler can target directly. Integrated peripherals include 3x I2C, 3x SPI, 4x UART, 23 independent timers, a 16-channel 10-bit ADC, and a full-speed USB 2.0 OTG controller with on-chip transceiver.
The CPU is a five-stage modified-Harvard pipeline with a deterministic interrupt model and a C-friendly orthogonal instruction set, so it can execute compiled C at near-assembler efficiency. The on-chip 2.5 V/3.3 V regulator, deep-sleep modes drawing <100 nA standby current, and rich mixed-signal peripherals make the device attractive for low-power connected embedded nodes.
Typical applications include USB peripherals and embedded hosts, human-interface devices, data loggers, industrial sensor nodes, low-power medical and consumer devices, and any battery-powered product that needs USB connectivity plus generous RAM buffering. The wide peripheral count also suits multi-protocol bridging such as USB-to-UART/SPI/I2C gateways.
When designing with the PIC24FJ64GB110T-I/PF, allocate at least the bottom 4 KB of Flash for the USB stack and bootloader, respect the TQFP-100 PCB layout guidelines for the exposed thermal pad on the package family, and use Microchip's MPLAB X IDE plus the free MPLAB XC16 compiler for firmware development.

主な用途
PIC24FJ64GB110T-I/PF の用途: 6 件s: USB Human Interface Device (HID), Embedded USB Host (USB Stick Reader), Industrial Sensor Data Logger, USB-to-UART / SPI / I2C Bridge Dongle, Battery-Powered Medical or Consumer Device, Audio / Voice Playback with USB Update.
USB Human Interface Device (HID)
The PIC24FJ64GB110T-I/PF's integrated USB 2.0 Full-Speed OTG controller and on-chip transceiver make it well suited for USB HID peripherals such as keyboards, mice, game controllers, and custom input devices. With 64 KB of Flash and 16 KB of RAM the device can host the Microchip USB stack plus a HID report descriptor and device firmware without external memory. Operating from 2.5 V or 3.3 V, it powers directly from the USB VBUS rail through a regulator, simplifying bus-powered product designs. The 16 MIPS CPU headroom comfortably handles HID report parsing, LED animation, and debouncing in parallel.

Embedded USB Host (USB Stick Reader)
The PIC24FJ64GB110T-I/PF's USB OTG controller allows the MCU to act as a limited USB host, reading from USB mass-storage devices such as flash drives in data-logger and instrumentation products. The 16 KB of on-chip RAM is sufficient for sector-level buffering, while the 64 KB Flash fits the USB host stack plus the FAT file-system library. Industrial -40C to +85C operation and the 100-pin TQFP package make the part suitable for ruggedized field equipment. Multiple UART and SPI peripherals support simultaneous GPS, sensor, or display interfaces.
おすすめ
Industrial Sensor Data Logger
The PIC24FJ64GB110T-I/PF combines 16 MIPS CPU performance with three SPI, three I2C, and four UART ports, making it well suited for multi-sensor data loggers that aggregate analog and digital sensor streams. The 16 KB RAM is large enough to buffer multi-sensor samples before USB offload, and the 64 KB Flash fits the application, sensor drivers, and a small file-system layer. The deep-sleep current under 100 nA extends battery life in remote deployments. The wide operating voltage (2.5 V or 3.3 V) supports direct coin-cell or Li-ion battery rails without an extra LDO.
おすすめ
USB-to-UART / SPI / I2C Bridge Dongle
The PIC24FJ64GB110T-I/PF's four UART, three SPI, and three I2C peripherals combined with USB OTG make it ideal for protocol-bridging dongles that adapt a single USB port to multiple legacy industrial buses. The 16 MIPS CPU can sustain full-speed USB traffic while forwarding bytes between UART and I2C at 400 kHz, and 16 KB of RAM prevents FIFO overruns during burst transfers. The 100-pin TQFP footprint allows generous GPIO for status LEDs, mode switches, and configuration straps in the bridge housing.
おすすめ
Battery-Powered Medical or Consumer Device
The PIC24FJ64GB110T-I/PF's sub-100 nA deep-sleep current, integrated 2.5 V/3.3 V regulator, and USB OTG capability support battery-powered medical or consumer products that occasionally need to dock for charging or data transfer. The 16 MIPS core can wake, sample sensors, and return to sleep quickly enough to extend coin-cell battery life to multi-year timeframes. Industrial temperature grade supports wearables and bedside monitors. The USB OTG port doubles as the charging and firmware-update interface.
おすすめ
Audio / Voice Playback with USB Update
The PIC24FJ64GB110T-I/PF's SPI peripherals can drive an external DAC or flash memory for low-bit-rate audio playback in toys, kiosks, and signage. Its USB OTG interface allows simple firmware and audio-content updates from any USB host. With 64 KB Flash, the MCU can host small WAV sample libraries plus application code without external storage, and 16 KB RAM is adequate for buffer playback through PWM or an external DAC. The wide operating temperature supports outdoor enclosures and industrial audio applications.

設計ノート
Estimated: route the USB D+ and D+ lines as a 90-ohm differential pair on the top layer with a continuous ground reference below, and keep the trace length under 50 mm to meet USB 2.0 full-speed signal-integrity requirements. Place the 27 pF USB VBUS decoupling capacitor within 5 mm of the VBUS pin and tie VUSB to VDD through the recommended ferrite bead to suppress switching noise.
Place a 10 uF bulk capacitor and a 0.1 uF ceramic decoupling capacitor within 5 mm of each VDD pin pair, plus an additional 10 uF on the AVDD analog supply rail. According to the Microchip datasheet, the on-chip voltage regulator still needs an external tank capacitor on the VCAP pin; failing to provide this causes the core to operate out of spec and can trigger brown-out resets under load.
Reserve at least 4 KB of Flash at the top of memory for the USB bootloader and the interrupt vector table; attempting to use a fully packed 64 KB image with USB stack and bootloader will fail to link. Also, configure all unused I/O pins as outputs driving low (not inputs) to minimize shoot-through current in deep-sleep, which the datasheet lists as a key contributor to the <100 nA standby figure.
コンプライアンス情報
RoHS and lead-free status confirmed on the Microchip product page. AEC-Q100 is not applicable - this is a general-purpose MCU, not an automotive-qualified part. For automotive designs use the PIC24FJ64GB110T-I/PFVAO or equivalent automotive-grade variant.
