A PIC microcontroller (MCU) is a compact, low-power programmable processor built on Harvard architecture, integrating CPU core, Flash program memory, RAM, and peripherals onto a single silicon die. PIC24F devices are 16-bit variants optimized for low-power (<100 nA standby) and connectivity-rich applications, sitting between the 8-bit PIC16/PIC18 families and 32-bit PIC32MX devices in Microchip's portfolio. They are widely deployed in embedded systems requiring USB connectivity, mixed-signal I/O, and deterministic real-time performance.
Key features include a modified Harvard architecture with 17-bit single-cycle hardware multiplier and 16-bit hardware divider, an 8 MHz internal oscillator with 4x PLL option and multiple divide options, and a C-compiler-optimized instruction set. The part supports a wide operating voltage range and integrates peripherals suited for USB device, host, and OTG roles without external PHY circuitry. Its 16-bit working register array enables efficient C code generation, while the dedicated USB OTG module eliminates the need for companion interface chips.
Typical applications include USB peripherals such as HID-class devices, human-interface devices, point-of-sale terminals, and consumer electronics requiring embedded host capability. The combination of low standby current, ample RAM buffering, and multiple serial channels also makes it suitable for industrial sensor hubs, data loggers, and battery-powered IoT bridges. Industrial-grade temperature rating supports silicon design through the -40C to +85C range, while the 100-pin TQFP provides generous I/O headroom.
When designing with this device, ensure that the USB OTG pin configuration matches the target role (device, host, or OTG) and that decoupling capacitors are placed close to the VDD/VSS pairs. The TQFP-100 footprint allows easy routing on 2-layer PCBs but a 4-layer stack-up with a dedicated ground plane is recommended for USB signal-integrity compliance.

کاربردهای معمول
PIC24FJ64GB110T-I/PT مناسب است برای 6 کاربردs: USB HID Peripherals (Keyboard, Mouse, Custom HID), USB Host Devices (Flash Drive Readers, Point-of-Sale), Industrial Sensor Hubs with USB Logging, Battery-Powered IoT Bridges (USB-C Charging + Sensor Uplink), Consumer Audio USB Accessories (Headset Dongles, MIDI), Medical Device Data Loggers (USB Offload to PC).
USB HID Peripherals (Keyboard, Mouse, Custom HID)
The PIC24FJ64GB110T-I/PT fits USB HID applications because it integrates a full-speed USB OTG controller and 16 KB of RAM - sufficient to buffer HID reports without external memory. The 16 MIPS performance from the 32 MHz core handles HID class drivers plus application logic concurrently. Placed on the device side of a USB cable with the on-chip transceiver driving D+/D- lines, it eliminates external PHY cost. Compared to a discrete MCU + FTDI bridge solution, the integrated approach saves PCB area and BOM cost.

USB Host Devices (Flash Drive Readers, Point-of-Sale)
The PIC24FJ64GB110T-I/PT supports USB host mode via its OTG controller, enabling embedded products to read/write USB mass-storage devices without a companion host processor. The 64 KB Flash holds FAT file-system stacks (e.g., Microchip's MDD library) plus application firmware, while the 16 KB RAM provides sector-buffer space. Operating from 2.0 V to 3.6 V allows direct Li-ion battery powering for portable POS terminals. Designers should add a USB power-switch IC for VBUS current limiting.
پیشنهادی
Industrial Sensor Hubs with USB Logging
The PIC24FJ64GB110T-I/PT fits industrial sensor hubs because it combines 3x I2C, 3x SPI, and 4x UART interfaces - sufficient for multi-sensor aggregation - with USB OTG for data offload. The industrial temperature rating (-40C to +85C) supports factory-floor deployment. Operating at 32 MHz delivers deterministic real-time response for control loops while the USB port streams logs to a host PC. Add a USB isolator for galvanic isolation in high-noise industrial environments.
پیشنهادی
Battery-Powered IoT Bridges (USB-C Charging + Sensor Uplink)
The PIC24FJ64GB110T-I/PT suits battery-powered IoT bridges because the PIC24F family's <100 nA standby current extends battery life, while the integrated USB OTG handles both charging and data on a single USB-C connector. The 16 KB RAM buffers sensor data between acquisition events and USB transfers. At 32 MHz the core handles BLE pass-through firmware (via UART to a companion BLE module) plus USB CDC enumeration concurrently. Pair with a Li-ion charger IC and a high-efficiency LDO for the 3.3 V rail.
پیشنهادی
Consumer Audio USB Accessories (Headset Dongles, MIDI)
The PIC24FJ64GB110T-I/PT works well in consumer audio USB accessories because the USB OTG controller supports USB Audio class 1.0 device operation, while the 32 MHz core processes MIDI messages or audio control commands with low latency. The 64 KB Flash fits USB Audio class descriptors plus vendor-specific extensions. For USB headset dongles, add a companion audio codec (e.g., Microchip's WM8904) on the I2S bus. The TQFP-100 footprint allows compact PCB designs.
پیشنهادی
Medical Device Data Loggers (USB Offload to PC)
The PIC24FJ64GB110T-I/PT fits medical data loggers because it integrates USB device mode for patient-data offload to a clinician's PC, while the 16 KB RAM buffers samples between acquisition cycles. The industrial temperature rating supports clinical environments. Operating from 2.0 V to 3.6 V enables direct coin-cell or Li-Po battery power for portable monitors. Add a real-time clock (e.g., MCP79410) on I2C for timestamped logs and comply with IEC 60601-1 for medical EMC.

یادداشت‌های طراحی
The PIC24FJ64GB110T-I/PT operates from 2.0 V to 3.6 V and draws <100 nA in standby mode. Place a 100 nF decoupling capacitor within 5 mm of each VDD/VSS pin pair (the TQFP-100 has multiple VDD/VSS pairs distributed across the package). Add a 4.7 uF bulk capacitor on the main 3.3 V rail. For USB applications, the VUSB pin requires its own 100 nF decoupling capacitor plus a ferrite bead on the VUSB-to-VDD path per Microchip datasheet recommendations.
For USB Full-Speed signal integrity on the TQFP-100 PCB, route the D+ and D- traces as a 90-ohm differential pair with length matching to within 2 mm. Place the 15 kohm pull-down resistor on D- (for full-speed device) as close to the MCU pin as possible. Use a 4-layer PCB with a continuous ground plane beneath the USB traces. The USB connector shield should be tied to chassis ground through a ferrite bead and 4.7 nF cap to meet ESD and EMI requirements.
Estimated: The TQFP-100 package has a thermal pad behavior dependent on PCB copper area; with the standard 2 oz copper pour connected to VSS pins, theta_JA is approximately 40-50 C/W. For designs operating near maximum 32 MHz and high I/O toggle rates, provide at least 1 square inch of ground copper. Keep the 32 MHz crystal traces short (under 10 mm) and guard them with a ground ring to reduce EMI radiation.
Do not leave the MCLR pin floating - it requires a 10 kohm pull-up to VDD for normal operation. The USB D+ pin must have a software-controlled 1.5 kohm pull-up to 3.3 V for device mode enumeration; this is enabled by the USB module configuration bits, not an external resistor. When migrating from PIC24FJ64GA110 to PIC24FJ64GB110, verify the USB pins are not inadvertently driven as GPIO, which prevents USB enumeration.
