PIC24FJ256GB606-E/PT - 16-bit 32MHz USB MCU, 256KB Flash | Microchip
MPN: PIC24FJ256GB606-E/PT ✗ Cuối đờiPIC24FJ256GB606-E/PT Tóm tắt
A 16-bit microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, data RAM, and peripherals into one package. PIC24F devices sit in the middle of Microchip's 8-bit PIC16/PIC18 and 32-bit PIC32MX portfolio, offering higher code density and DSP-friendly instructions than 8-bit parts while remaining simpler and lower-cost than 32-bit Cortex-M parts. Within the PIC24F family, the GB-series targets low-power USB-connected embedded applications, combining eXtreme Low Power (XLP) sleep modes (<100 nA standby) with a full-speed USB 2.0 OTG controller.
Key features include 16 channels of 12-bit (or 10-bit) Analog-to-Digital Conversion, four UART, three SPI, and three I2C serial interfaces, 23 independent timers, and a real-time clock calendar (RTCC). The dual-partition Flash with Live Update enables firmware upgrades where the application keeps running from one partition while the other is reprogrammed, eliminating device downtime during field updates. AEC-Q100 qualification makes the -E/PT grade suitable for automotive and harsh-environment deployments.
Typical applications include portable medical/fitness devices, USB-connected industrial sensors, battery-powered data loggers, USB HID peripherals, and consumer products requiring low standby current combined with on-board USB host/device/OTG capability. Designers benefit from the Microchip MPLAB X IDE and the free MPLAB Code Configurator (MCC) plugin for rapid peripheral setup.
When designing with this part, budget sufficient decoupling (100 nF + bulk) near each VDD pin, follow USB-OTG layout guidelines (90-ohm differential, common-mode choke), and select the appropriate regulator (3.3V typical) to supply both the digital core and the USB transceiver rail. The 64-TQFP package requires a 10x10 mm PCB footprint; reference Microchip's TQFP-64 land-pattern note for solder-mask and paste recommendations.

Ứng dụng tiêu biểu
PIC24FJ256GB606-E/PT phù hợp cho 7 Áp dụngs: Portable Medical and Fitness Devices, USB HID and Consumer Peripherals, Industrial USB Data Loggers, Automotive Body and HMI Modules, Battery-Powered IoT Sensor Nodes, USB Barcode / Label Printers, USB-OTG Audio Devices.
Portable Medical and Fitness Devices
The PIC24FJ256GB606-E/PT is well matched to portable medical and fitness devices that require USB data transfer and long battery life. With sub-100nA XLP standby current and 32 KB RAM, the MCU can wake on a sensor interrupt, sample data, store it in flash, and return to sleep without taxing the coin-cell. The 12-bit ADC with 16 channels supports multi-sensor inputs (heart-rate, temperature, motion) with adequate resolution for fitness telemetry.

USB HID and Consumer Peripherals
The PIC24FJ256GB606-E/PT's integrated USB 2.0 Full-Speed OTG controller, 4x UART and 3x SPI interfaces make it ideal for USB HID peripherals such as keyboards, mice, game controllers, and custom input devices. With 256 KB Flash and the Microchip USB stack (USB Device / HID / CDC / MSD classes), engineers can implement full HID boot-loader plus application code without external memory. The dual-partition Live Update feature enables in-field firmware upgrades over USB.
Được đề xuất
Industrial USB Data Loggers
For industrial USB data loggers, the PIC24FJ256GB606-E/PT delivers AEC-Q100 qualified reliability plus the USB-OTG controller needed to dump log data directly to a USB stick without a PC. The 256 KB dual-partition flash allows a large rolling buffer and on-board file system; the 23 timers and 16-channel 12-bit ADC handle multi-sensor sampling at deterministic rates. The extended -40C to +125C temperature range supports factory-floor deployments.
Được đề xuất
Automotive Body and HMI Modules
AEC-Q100 qualification and -40C to +125C operation allow the PIC24FJ256GB606-E/PT to drive automotive body-control and HMI modules such as HVAC keypads, mirror controls, and seat-position switches. The 53 I/O pins can directly drive LED matrices, button-scanning matrices, or rotary encoders. USB OTG is convenient for service-port diagnostics and firmware updates at the dealership. The 32 KB RAM supports small RTOS schedulers for multi-task button debouncing.
Được đề xuất
Battery-Powered IoT Sensor Nodes
Battery-powered IoT sensor nodes benefit from the PIC24FJ256GB606-E/PT's XLP sleep modes (<100nA typical), 12-bit ADC for sensor reads, and three I2C / SPI ports for adding sensors or radio modules. The MCU can sleep for hours between wake events, briefly wake to transmit over an attached radio (e.g. SPI-attached Sub-GHz or BLE module), and return to sleep, achieving multi-year coin-cell life. The 256 KB flash is large enough for OTA firmware storage.
Được đề xuất
USB Barcode / Label Printers
USB-connected label and barcode printers can use the PIC24FJ256GB606-E/PT as the main system controller. The USB OTG port accepts print jobs from a host PC or reads jobs directly from a USB mass-storage dongle in OTG host mode. With 53 I/O, the MCU can drive a stepper motor controller, a thermal print-head, an LCD, and a button matrix. 256 KB Flash supports custom font tables and printer command languages (ZPL, EPL, ESC/P).
Được đề xuất
USB-OTG Audio Devices
USB-OTG audio devices such as USB microphones, USB DACs, and USB headsets can use the PIC24FJ256GB606-E/PT as the controller that manages USB isochronous audio streaming. The MCU handles USB protocol, button/HID events for volume/play-pause, and feeds digital audio to an external CODEC over I2S. The 32 KB RAM is sufficient for HID ring buffers and small audio-mixing tasks. Designers should add an external audio CODEC for actual DAC/ADC conversion.

Ghi chú thiết kế
The PIC24FJ256GB606-E/PT requires a 4-layer PCB with a continuous ground plane beneath the 64-TQFP footprint for proper USB-OTG impedance control and EMI performance. Place a 100nF ceramic decoupling capacitor on each VDD pin (within 3 mm of the pin) and a single 4.7uF bulk capacitor near the package. Route the USB D+/D- pair as a 90-ohm differential with length matching within 150 mil, and add a common-mode choke near the connector for ESD/EMI mitigation.
Estimated: at 32 MHz full-speed operation with all peripherals active, the PIC24FJ256GB606-E/PT typically draws ~25-30 mA from a 3.3V supply. For USB-OTG host mode where the internal 5V boost regulator drives VBUS, ensure the input supply can deliver at least 250 mA peak. For battery designs, gate the USB-OTG boost regulator off in sleep mode (set VBUSCHEN=0) to drop standby current below 1uA.
Do not leave the VUSB pin (pin 41) floating - it must be tied to VDD through a 1uF ceramic decoupling capacitor. The PGEC1/PGED1 pins (RB6/RB7) double as in-circuit debug ports; if your PCB design uses these pins for application I/O, plan an ICSP header footprint and series resistors to avoid contention with the debugger. The Live Update dual-partition Flash requires the application to manage the partition table in config words - omitting this causes the Live Update feature to be inoperative.
Place the 32.768 kHz crystal (if used for RTCC) within 5 mm of the SOSCI/SOSCO pins, with short traces and a grounded guard ring. The 4 MHz or higher system crystal should likewise be placed near the OSCI/OSCO pins. Avoid routing high-frequency digital signals (USB, SPI clock > 10 MHz) directly over the analog AVSS/AVDD pair or near the ADC reference pins to maintain ADC accuracy at 12-bit resolution.
The USB D+/D- signals on the PIC24FJ256GB606-E/PT require 90-ohm differential impedance and length matching within 150 mil (3.8 mm). Add a 27 ohm series resistor on each line near the MCU for source termination, and a common-mode choke (such as ACM2012) near the USB connector. For full-speed USB, the rise/fall time should be 4-20 ns; for low-speed, 75-300 ns. Verify with a USB-IF-compliant signal-quality test before FCC/CE submission.
