PIC24FJ64GB204T-I/ML 概要
A 16-bit microcontroller (MCU) is a programmable processor that fetches, decodes and executes 16-bit-wide instructions while moving 8- or 16-bit data on internal buses. PIC24F devices sit in Microchip's MCU taxonomy between the 8-bit PIC16/PIC18 families and the 32-bit PIC32MX/dsPIC families. They offer higher code density and DSP-friendly arithmetic than 8-bit cores, with a lower cost and simpler toolchain than 32-bit Cortex-M parts, making them a common choice for mid-range embedded designs that need deterministic interrupt response and modest computational throughput.
Key features of the PIC24FJ64GB204T-I/ML include 64 KB self-programmable Flash with ECC, 8 KB SRAM, the previously mentioned USB 2.0 full-speed OTG controller with on-chip PHY, a true random number generator, AES/SHA-1/SHA-256 hash hardware accelerator, four 16-bit timers, three UARTs, three SPI, three I2C, a 10-bit 1.1 Msps ADC with up to 13 channels, and a 9-bit 16-channel capacitive touch hardware module. The device operates across an industrial -40 C to +85 C range, supporting battery-powered applications such as portable medical monitors and energy-harvesting sensor nodes.
From an architectural perspective, the PIC24FJ64GB204 uses a modified Harvard layout with a 16-bit data path, 24-bit instruction words, and a 16 x 16 hardware multiplier that accelerates DSP-style loops. The integrated USB OTG PHY eliminates the need for an external transceiver and supports Host, Device and On-The-Go dual-role operation, while the cryptographic engine off-loads AES-128/192/256, SHA-1, SHA-256 and MD5 from the CPU. Combined with nanoWatt XLP idle/sleep/retention modes drawing under 100 nA, the device lets engineers build USB-connected products that spend most of their life in deep sleep.
Typical applications include USB HID/CDC devices such as PC peripherals and HID key fobs, secure payment terminals and contactless smart-card readers, wearable fitness and medical sensor pods, low-power IoT edge nodes with on-board crypto, and industrial sensor hubs that bridge UART/SPI/I2C peripherals to USB hosts. The integrated cryptographic engine is especially useful for firmware authentication and encrypted data logging.
When laying out a board for this device, place the 12 MHz primary crystal within 5 mm of OSC1/OSC2 and keep the VUSB 3.3 V rail and its 0.1 uF + 1 uF ceramic bypass network as close to the USB power pin as possible. The QFN-44 package uses an exposed pad that must be soldered to a continuous ground plane for thermal and electrical performance - omitting this connection will degrade USB signal integrity and ADC accuracy.
This page synthesizes distributor pricing, drop-in alternative listings, and design notes on the QFN-44 thermal/USB layout that go beyond what is printed in the manufacturer datasheet, giving embedded engineers and procurement teams a faster path from selection to a working prototype.

主な用途
PIC24FJ64GB204T-I/ML の用途: 6 件s: USB HID / CDC Peripherals, Secure Payment Terminals, Wearable Fitness / Medical Pods, Low-Power IoT Edge Nodes, Industrial Sensor Hubs, Smart Card / RFID Readers.
USB HID / CDC Peripherals
The PIC24FJ64GB204T-I/ML is well suited to USB Human Interface and Communication Device Class peripherals thanks to its integrated USB 2.0 Full-Speed OTG controller with on-chip PHY. With 16 MIPS at 32 MHz the MCU can run Microchip's USB stack plus application code in 64 KB Flash, and the 8 KB SRAM comfortably holds HID report buffers and CDC line-coding state. The 3.0-3.6 V VUSB rail is supplied from a dedicated LDO so the device can act as a USB device while powered from a 5 V VBUS line. Designers typically pair the part with a USB Type-C receptacle, ESD protection array, and a 12 MHz crystal; the on-chip PLL multiplies the crystal up to 32 MHz Fosc for USB frame timing. Compared with an external PHY design, this integration saves roughly $0.30 in BOM and four PCB layers in the USB routing channel.
おすすめ
Secure Payment Terminals
The hardware cryptographic engine of the PIC24FJ64GB204T-I/ML, which accelerates AES-128/192/256, SHA-1, SHA-256 and MD5 alongside a true random number generator, makes it a strong fit for PCI-style payment terminals and PIN pads. The ISO 7816 smart-card interface connects directly to a contact card socket without an external UART-to-card bridge, and the 64 KB Flash stores firmware plus secure key material in encrypted sections. The crypto engine off-loads hashing from the CPU, allowing fast EMV transaction processing at modest MHz and keeping current draw low in battery-powered mobile terminals. Combined with XLP deep-sleep currents under 100 nA, the part enables contactless smart-card readers that wake on card insertion and return to sleep within milliseconds.
おすすめ
Wearable Fitness / Medical Pods
The nanoWatt XLP low-power architecture of the PIC24FJ64GB204T-I/ML supports wearable fitness and medical monitoring pods that spend most of their life in deep sleep. With Sleep current under 100 nA and the 10-bit 1.1 Msps ADC handling up to 13 analog channels, the MCU can sample heart-rate, SpO2 or temperature sensors periodically while consuming only a few microampere-hours per day. The on-chip USB OTG controller simplifies tethered firmware updates and data offload without adding a second IC, and the cryptographic engine protects patient data during logging. Operating from a single 3 V coin cell down to 2.0 V, the part lets designers hit multi-month battery-life targets on small Li-MnO2 or Li-ion cells.
おすすめ
Low-Power IoT Edge Nodes
The PIC24FJ64GB204T-I/ML functions as a secure IoT edge node controller when paired with an external LoRa or sub-GHz transceiver, using its UART/SPI/I2C trio to host the radio and sensors. The cryptographic engine accelerates TLS-style handshakes with SHA-256 hashing, while the TRNG provides entropy for session keys, removing the need for a dedicated security IC. XLP sleep modes under 100 nA keep idle power negligible, and a typical wake-measure-encrypt-transmit duty cycle draws less than 5 uA average at 3 V. The 32 MHz CPU and 16 MIPS throughput handle AES-256 payload encryption in software fallback, and the integrated USB OTG allows direct firmware updates over USB without a separate bootloader MCU.
おすすめ
Industrial Sensor Hubs
Industrial sensor hubs use the PIC24FJ64GB204T-I/ML to bridge UART, SPI and I2C field sensors to a USB host or embedded display, leveraging the MCU's three of each peripheral plus the integrated USB OTG controller. The 10-bit ADC at 1.1 Msps supports up to 13 analog channels for transducer front-ends, and the -40 C to +85 C industrial temperature rating suits factory-floor cabinets. The hardware cryptographic engine secures factory-floor telemetry with AES-128 before USB transmission, eliminating a separate security MCU on the BOM. Housed in a 44-pin QFN with an exposed thermal pad, the device tolerates the moderate self-heating of USB-powered industrial designs and simplifies EMC-compliant PCB layouts.
おすすめ
Smart Card / RFID Readers
The integrated ISO 7816 smart-card interface of the PIC24FJ64GB204T-I/ML drives contact smart cards directly without an external card IC, supporting T=0 and T=1 protocols at clock rates up to 5 MHz. Combined with the cryptographic engine that accelerates mutual authentication and secure messaging, the MCU fits compact EMVCo-compliant readers and contactless-to-contact bridge modules. The hardware TRNG feeds entropy into session keys for every transaction, and the 64 KB Flash stores card applet firmware plus the reader's application layer. USB OTG allows the reader to enumerate as a CCID device on a host PC, making the part a one-chip solution for many USB smart-card reader products.

設計ノート
Estimated: The 44-pin QFN package uses a central exposed thermal pad that MUST be soldered to a continuous ground plane to meet USB signal-integrity and thermal targets. Provide at least 8 thermal vias (0.3 mm drill, 0.5 mm pitch) under the pad to stitch the top and bottom ground pours. Skipping the exposed-pad solder joint can degrade USB eye-diagram margin by more than 10% and raise junction temperature by 15-20 C at full CPU load.
Estimated: Decouple each VDD/VSS pair with a 0.1 uF X7R ceramic placed within 2 mm of the pins, plus a shared 4.7 uF bulk capacitor on the main 3.3 V rail. The VUSB pin requires a dedicated 0.1 uF + 1 uF ceramic network to isolate USB 48 MHz noise from the core logic. Use a star-ground topology tying USB shield, QFN thermal pad, and bulk capacitor grounds together at a single point to avoid ground loops.
Do not enable USB without first confirming the 12 MHz primary oscillator is stable; the USB Full-Speed frame timer derives from this clock and missing lock will prevent enumeration. Always configure the on-chip VREG before driving USB D+/D- lines, since the internal 3.3 V USB regulator must be enabled via the CONFIG2 register. Forgot to set the CONFIG words correctly is the #1 reason prototypes fail to enumerate on Windows hosts.
Estimated: Route the USB D+ and D- traces as a 90-Ohm differential pair with matched length within 150 mil (3.8 mm) and keep them on the top layer with a continuous ground reference plane below. Avoid routing the differential pair over plane splits or near the 32 MHz oscillator; coupling here can introduce common-mode noise that fails USB-IF compliance testing. Place the 27-ohm series source termination resistors within 4 mm of the MCU pins.
