PIC24FJ64GB106T-I/PT Présentation
A 16-bit microcontroller (MCU) is a programmable processor that uses a 16-bit data path, instruction word, and register file, sitting in the hierarchy between 8-bit MCUs (e.g., PIC16) and 32-bit MCUs (e.g., ARM Cortex-M). The PIC24F family is Microchip's mid-range 16-bit line, succeeding the PIC18 and offering a smooth migration path to the 32-bit PIC32MX family. eXtreme Low Power technology adds nanoWatt features such as <100 nA standby current and on-the-fly clock switching, enabling battery-powered designs without sacrificing throughput.
Key features include USB OTG with integrated PHY, up to 16 MIPS throughput at 3.3 V, peripheral pin select (PPS) for flexible I/O mapping, a 16-channel 10-bit ADC, RTCC with calendar mode, and a charge time measurement unit (CTMU) for capacitive touch sensing. The 64-pin TQFP offers 51 digital I/O pins with individually controllable interrupts and 5 mA sink/source capability per pin, providing abundant connectivity for mixed-signal designs.
The PIC24FJ64GB106 architecture uses a modified Harvard structure with separate program and data buses. Code is fetched from Flash via a 24-bit-wide path, while SRAM is accessed through a 16-bit data path. This dual-bus arrangement lets the CPU prefetch the next instruction while completing the current one, sustaining 1 MIPS/MHz performance and deterministic interrupt latency. The integrated USB OTG controller, when paired with the on-chip transceiver, eliminates the need for an external USB PHY.
Typical applications include USB peripherals (HID, CDC, mass storage), battery-powered industrial sensors, capacitive touch human-machine interfaces (HMIs), portable medical telemetry, and embedded dataloggers. The combination of USB OTG and eXtreme Low Power makes this MCU well suited to mobile accessories, point-of-sale terminals, and home automation hubs.
Designers should plan for a 1 µF decoupling capacitor close to every VDD pin and a 10 µF bulk capacitor on the regulator output, route the USB D+/D- traces as a 90-ohm differential pair with matched length, and place the 12 MHz crystal within 5 mm of the OSC1/OSC2 pins to avoid startup failures or USB timing errors.

Applications typiques
PIC24FJ64GB106T-I/PT convient pour 6 applications: USB HID Peripherals, Industrial Sensor Dataloggers, Capacitive Touch HMI Panels, Portable Medical Telemetry, USB Mass Storage and CDC Devices, Home Automation Gateways.
USB HID Peripherals
The PIC24FJ64GB106T-I/PT is ideal for USB Human Interface Device designs such as keyboards, mice, game controllers, and custom input panels because its integrated USB 2.0 Full-Speed OTG transceiver eliminates the need for an external PHY, saving PCB area and BOM cost. With 16 MIPS throughput at 32 MHz, the core can run the USB HID stack plus keyscan, LED driving, and capacitive touch polling concurrently. The 16 KB RAM is sufficient for HID report buffers, while the 64 KB Flash accommodates the Microchip USB stack and application firmware. The TQFP-64 footprint allows 51 GPIO for matrix scanning or LED PWM.
Recommandé
Industrial Sensor Dataloggers
For battery-powered industrial sensor dataloggers, the PIC24FJ64GB106T-I/PT offers eXtreme Low Power technology that drops below 100 nA in Deep Sleep mode, enabling multi-year battery life on a single 3.6 V Li-SOCl2 cell. The 16-channel 10-bit ADC, 23 timers, and 3x I2C / SPI interfaces support simultaneous multi-sensor sampling, while the 16 KB RAM buffers logged data before batch USB transfers. The 2.0 V minimum supply extends useful operation as the battery discharges. The industrial -40 °C to +85 °C temperature range suits outdoor or factory-floor deployments.
Recommandé
Capacitive Touch HMI Panels
The PIC24FJ64GB106T-I/PT integrates the CTMU (Charge Time Measurement Unit), which implements robust capacitive touch sensing without an external touch controller IC, reducing BOM cost and PCB complexity for human-machine interfaces. Combined with 64 KB Flash and 16 MIPS throughput, the MCU can run a touch algorithm, LED feedback, and a USB CDC link to a host simultaneously. The TQFP-64 footprint provides 51 GPIO for 12 to 16 touch electrodes plus RGB LED drivers, and PPS pin selection simplifies trace routing in tight panel layouts.
Recommandé
Portable Medical Telemetry
In portable medical telemetry such as pulse oximeters, glucose meters, and wearable patches, the PIC24FJ64GB106T-I/PT provides USB OTG for charging cradle data exchange while the eXtreme Low Power modes extend battery life. The 16 KB RAM buffers measurement history, and the 16-channel 10-bit ADC interfaces directly with analog front-ends for SpO2 or ECG signals. The 32 MHz core processes filtering algorithms in real time, and the TQFP-64 package fits compact wearable enclosures. AEC-Q100 grade is not required for this medical consumer segment.
Recommandé
USB Mass Storage and CDC Devices
USB mass storage devices such as portable card readers and CDC virtual COM ports benefit from the PIC24FJ64GB106T-I/PT's on-chip USB OTG full-speed controller, which supports MSC, CDC, and HID composite devices without external PHYs. The 64 KB Flash holds the Microchip USB MSD/CDC stack, FAT file system, and application logic, while the 16 KB RAM serves as a sector cache during SD card writes. The 51 GPIO provides ample SD card interfacing and indicator LED control. Tape-and-reel packaging supports high-volume SMT assembly.
Recommandé
Home Automation Gateways
The PIC24FJ64GB106T-I/PT fits home automation gateway and bridge nodes that aggregate Zigbee, Sub-GHz, or Wi-Fi modules via UART or SPI and present a USB CDC interface to the home router or Pi-class host. Its 4 UARTs handle simultaneous module communications, and the 23 timers provide precise protocol timing for Sub-GHz radio frames. With <100 nA Deep Sleep current and RTC calendar mode, battery-backed nodes run for years. The 3x SPI supports high-speed Flash storage for event logs and configuration data, while USB OTG enables field firmware updates from a phone.

Principaux différenciateurs
- Integrated USB OTG transceiver without external PHY (vs PIC24FJ64GA106T-I/PT)
- 128 KB Flash upgrade path on the same footprint (vs PIC24FJ64GB106-I/PT)
- eXtreme Low Power standby current below 100 nA (vs PIC24FJ128GB106-I/PT)
Notes de conception
Place a 1 µF X7R ceramic decoupling capacitor within 3 mm of every VDD pin and a single 10 µF tantalum or ceramic bulk capacitor on the regulator output. The USB OTG transceiver requires a low-noise 3.3 V rail with <50 mVpp ripple; switching regulators above 1 MHz must be filtered to avoid injection into the USB signal. Tie unused VDD pins to the same rail; floating pins can cause 5 to 10 mA phantom current.
Route the USB D+ and D- signals as a 90 Ω differential pair with matched length to within 150 mil and continuous ground reference on the layer below. Place the 12 MHz crystal or resonator within 5 mm of OSC1/OSC2, with short traces and a guard ring tied to analog ground. Keep high-current switching traces (LED drivers, motor PWM) away from the USB pair and the crystal area to avoid radiated EMI coupling.
Configuration bits must be set before code execution or the USB module may not start; in particular, the IESO bit, PLLDIV setting, and the JTAG/ICD pin reassignment affect bootloader mode. Leaving ICSP pins (RB6/RB7) as analog by default can cause 1 to 2 mA additional draw if not configured as digital. The VBUS pin must be tied to VDD through a 10 kΩ resistor or left floating if USB host role is unused, otherwise the OTG controller will not detect cable insertion.
At full 32 MHz operation with all peripherals active, the PIC24FJ64GB106T-I/PT draws approximately 20 mA from 3.3 V, dissipating 66 mW. The TQFP-64 package has theta_JA of around 50 °C/W, so junction temperature rises roughly 3 °C above ambient with no thermal relief - well within the 125 °C absolute maximum. For closed enclosures, derate ambient by 10 to 15 °C and consider slowing peripherals via PMD bits if heat is a concern.
Informations de conformité
Industrial temperature grade -40 °C to +85 °C only; for AEC-Q100 automotive applications use PIC24FJ64GB106-I/PF (not in same footprint) or move to dsPIC33 family. RoHS and REACH compliance per Microchip product page; halogen-free per Microchip environmental certification.
