PIC24FJ256GB606T-I/PT 概要
A microcontroller (MCU) is a single-chip computer integrating a CPU, memory (Flash/RAM), and programmable peripherals. The PIC24F family belongs to the 16-bit MCU hierarchy and sits between 8-bit PIC MCUs and 32-bit ARM Cortex-M devices, offering higher code density and richer peripherals while retaining low-power operation (<100 nA standby current per Microchip). MCUs form the control core of embedded systems across industrial, medical, and consumer products.
Key features include 256 KB Flash (85.5K x 24 words) with dual-partition Live Update, 32 KB SRAM, USB 2.0 FS with OTG, integrated peripherals (I2C, SPI, UART, PMP), a 16-channel 12-bit ADC, and configurable low-power Sleep/Idle modes. The part is specified over the -40C to +85C industrial temperature range and ships in tape-and-reel packaging for high-volume surface-mount assembly.
The PIC24FJ256GB606 architecture combines a Harvard bus structure, a hardware multiply/divide unit, and DMA into a single low-power core. Dual-partition Flash enables in-field firmware upgrades without downtime — one partition runs while the other updates — critical for industrial and medical devices requiring continuous availability.
Typical applications include USB peripherals (HID, CDC, mass storage), portable medical/fitness monitors, industrial control and human-machine interface (HMI) panels, low-power IoT sensor nodes with USB diagnostics, and USB-enabled battery chargers. The Live Update feature makes it especially attractive for always-on products that must accept firmware updates safely.
When designing with this device, plan the PCB layout around the 64-pin TQFP with USB trace impedance controlled to 90 ohms differential. Use the dual-partition Flash for failsafe OTA updates, and verify the SRAM allocation (32 KB) against your largest buffer need at compile time.

主な用途
PIC24FJ256GB606T-I/PT の用途: 7 件s: USB HID Peripheral Devices, Portable Medical and Fitness Devices, Industrial HMI Control Panels, USB Mass Storage and Data Loggers, IoT Sensor Nodes with USB Diagnostics, USB Battery Chargers and Power Banks, Automotive Infotainment Auxiliary Modules.
USB HID Peripheral Devices
The PIC24FJ256GB606T-I/PT is well-suited to USB HID peripherals such as keyboards, mice, game controllers, and custom HID input devices. Its integrated USB 2.0 full-speed transceiver with device/host/OTG capability eliminates the need for an external PHY, reducing BOM cost and PCB area. The 256 KB dual-partition Flash supports the full Microchip USB stack plus HID report descriptors without code-size constraints, while 32 KB of SRAM comfortably holds multiple HID report buffers and runtime state. At 32 MHz the 16 MIPS core handles USB polling (1 ms interval) and HID report synthesis with low CPU headroom remaining for application logic. Place the part near the USB connector with 90-ohm impedance-controlled D+/D- traces; the integrated pull-up resistor on D+ enables bus-powered self-powered designs without external components.
おすすめ
Portable Medical and Fitness Devices
The PIC24FJ256GB606T-I/PT's sub-100 nA standby current and USB connectivity make it a strong fit for portable medical and fitness applications including glucose meters, pulse oximeters, and activity trackers. Battery life is dominated by standby drain between measurements, and the family datasheet's <100 nA figure enables multi-year coin-cell operation. The 32 KB SRAM supports continuous sensor data buffering between USB sync events, while 256 KB Flash holds application firmware plus the USB CDC stack for data upload to a PC. The 12-bit ADC (channel count pending datasheet verification) samples analog sensor outputs at low rates to minimize active current. Industrial -40C to +85C temperature grade supports wearable applications where skin-contact heating must not exceed safe limits.
おすすめ
Industrial HMI Control Panels
The PIC24FJ256GB606T-I/PT's Parallel Master Port (PMP) and USB interface make it ideal for industrial human-machine interface (HMI) panels that drive TFT LCDs and connect to a host controller or service laptop. The PMP can interface directly to TFT controllers in 16-bit parallel mode, offloading display refresh from the CPU. Dual-partition Flash supports failsafe firmware updates on factory floors where equipment downtime is expensive. The 64-pin TQFP package exposes enough GPIO for keypad scanning, LED indicators, and serial communication channels (I2C, SPI, UART) to sensors and motor drivers. The industrial -40C to +85C temperature range and USB diagnostics port allow field engineers to pull logs and reflash firmware without opening the enclosure.
おすすめ
USB Mass Storage and Data Loggers
The PIC24FJ256GB606T-I/PT can host a USB mass storage device when paired with an external SD card or NAND flash interface, enabling portable data loggers that appear as USB drives to any PC. The 256 KB Flash holds the FAT file system library plus application logic; 32 KB RAM supports sector buffering for USB transfers at full-speed rates. Dual-partition Flash is particularly useful for data loggers: while one partition logs new samples, the other can receive firmware updates without interrupting data acquisition. The integrated USB OTG mode also lets the logger connect to a USB host such as a phone or tablet for wireless offload via a USB-to-BLE bridge, expanding connectivity options without an on-board radio.
おすすめ
IoT Sensor Nodes with USB Diagnostics
The PIC24FJ256GB606T-I/PT fits IoT sensor nodes that need USB as a service, configuration, and firmware-update port. Many IoT deployments lack a wireless infrastructure for last-mile updates, so a USB diagnostic port is a robust fallback. The 256 KB Flash stores application code, wireless protocol stacks (when paired with an external radio), and the USB CDC stack for command-line diagnostics. Sleep current under 100 nA enables multi-year battery life for intermittently-connected sensors. The part's 16 MIPS performance is sufficient to handle periodic sensor sampling, USB enumeration, and OTA firmware updates across the dual-partition Flash without architectural complexity.
おすすめ
USB Battery Chargers and Power Banks
The PIC24FJ256GB606T-I/PT's USB OTG capability makes it suitable as the controller in smart USB battery chargers and power-bank products that negotiate charge profiles with USB hosts. The MCU can act as a USB device to advertise its charge status via HID or vendor-specific reports, or as a USB host to deliver power to connected devices. The 12-bit ADC (peripheral channel count pending verification) monitors battery voltage and current with adequate resolution for lithium chemistries. Dual-partition Flash enables safe in-field firmware updates that improve charge algorithms over time. 32 KB RAM is sufficient for charge state machines, USB descriptors, and display buffering on small status screens.
おすすめ
Automotive Infotainment Auxiliary Modules
The PIC24FJ256GB606T-I/PT supports automotive auxiliary infotainment modules such as USB media-port extenders, climate-control knobs, and ambient lighting controllers that communicate with the head unit over USB. Although the standard I-grade part is rated -40C to +85C, Microchip offers the E-grade variant (-40C to +125C) for under-dash and engine-bay-adjacent applications. The USB device stack enables plug-and-play detection by the head unit without custom drivers, while the 32 KB RAM handles HID input reports and status updates with minimal latency. Dual-partition Flash supports OTA firmware campaigns run by OEMs, allowing bug fixes without dealer visits.

設計ノート
Route USB D+ and D- as a 90-ohm differential pair with controlled impedance; keep total length under 50 mm and avoid splits in the ground plane beneath the pair. Place the Vbus detect pin close to the USB connector's Vbus pin with a 10 kohm pulldown. Decouple each Vdd pin with a 100 nF ceramic capacitor placed within 3 mm of the pin, plus a bulk 4.7 uF tantalum or ceramic near the package.
Estimated: At 32 MHz active current consumption is approximately 15-20 mA per family datasheet curves, so a 3.3 V regulator must supply at least 30 mA sustained plus USB inrush peaks. For battery-powered designs, plan the duty cycle carefully: 1 ms USB polling keeps the core active, so use USB suspend (500 uA max per USB 2.0 spec) when the host is idle to drop into Sleep mode and leverage the <100 nA standby figure.
Do not enable the JTAG pins as GPIO without first disabling the JTAG fuse bits in your configuration; the default PTG pin functions overlap JTAG. Ensure the MCLR pin has a 10 kohm pullup to Vdd and a 100 nF capacitor to ground for proper reset behavior. When using dual-partition Live Update, verify the boot loader's partition-switch logic before locking configuration bits, since misconfigured boot vectors can brick the part.
