PIC24FJ512GB610-I/PT 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), working memory (RAM), and a peripheral set on one die. Within Microchip's taxonomy, the PIC24FJ family sits in the 16-bit modified-Harvard performance tier above the 8-bit PIC16/PIC18 families and below the dsPIC33/PIC32 lines, offering 16 MIPS throughput with a C-friendly architecture. The GB610 sub-family adds USB connectivity, dual-partition Flash for Live Update firmware swaps, and is positioned for industrial, medical/fitness, computer, and portable applications requiring long battery life.
Key features include a 2.0 V to 3.6 V wide single-supply operating range, configurable 10-bit/12-bit ADC resolution, multiple serial interfaces (UART, SPI, I2C), and hardware Cryptographic Engine for AES on select variants. The Live Update dual-partition Flash eliminates firmware update downtime by allowing background writes to an inactive partition followed by atomic switchover. The USB 2.0 Full-Speed OTG module supports both host and device roles, making the part suitable for self-powered peripherals.
The PIC24FJ512GB610-I/PT ships in a 100-pin TQFP (12x12 mm) package. The /PT suffix denotes the TQFP package and tray packaging. The -I/ suffix denotes the industrial temperature grade. Pin-compatible variants include PIC24FJ256GB610 and PIC24FJ1024GB610 in the same TQFP-100 footprint, enabling memory-size scaling without PCB rework.
Typical applications include industrial control panels, USB medical/fitness devices, portable data loggers, computer peripherals, and Human Interface Devices (HID). The Live Update feature suits remote firmware update scenarios where field downtime is unacceptable.
When designing with this device, place a 10 µF bulk + 0.1 µF decoupling pair adjacent to each VDD/VSS pair and follow Microchip's Explorer 16/32 Development Board reference layout for the TQFP-100 PIM socket. Plan Live Update memory partitioning during linker script design; each partition needs its own boot block and IVT.

主な用途
PIC24FJ512GB610-I/PT の用途: 7 件s: Industrial Control Panels, USB Medical/Fitness Devices, Portable Data Loggers, Computer Peripherals (HID/Keyboard/Storage), Human Interface Devices with OTA Update, USB OTG Industrial Peripherals (Host Role), Secure Boot/Update Industrial Gateways.
Industrial Control Panels
The PIC24FJ512GB610-I/PT fits industrial control panels because its 85 I/O pins drive multiple button matrices, LEDs, and relay outputs from a single 3.3 V rail without external expanders. The 512 KB Flash hosts full Modbus/RTU stacks plus HMI graphics while 32 KB RAM buffers protocol transactions, and the -40 °C to +85 °C industrial temperature grade tolerates cabinet thermal stress. Verified Web Data confirms USB OTG supports service-port firmware updates via Live Update dual-partition Flash, allowing plant technicians to push new HMI logic without halting production.
おすすめ
USB Medical/Fitness Devices
USB-connected medical/fitness peripherals rely on the PIC24FJ512GB610-I/PT's integrated USB 2.0 Full-Speed OTG controller to stream sensor data to a host PC without an external PHY, reducing BOM cost and PCB area. The 512 KB dual-partition Flash enables Live Update for FDA-compliant firmware revisions without device downtime, while 32 KB RAM handles concurrent USB endpoint buffering and DSP pre-processing. The AES hardware accelerator secures patient data between sensor and host, making the part suitable for blood-pressure cuffs, glucose meters, and fitness wearables operating from 2-3.6 V.
おすすめ
Portable Data Loggers
Portable battery-powered data loggers benefit from the PIC24FJ512GB610-I/PT's wide 2.0-3.6 V supply range allowing direct operation from two AA cells or a Li-ion pack. The 512 KB Flash stores months of 16-bit ADC samples while 32 KB RAM acts as a circular sample buffer, and the USB Full-Speed device port enables fast log offload to a host PC. The Live Update dual-partition Flash lets manufacturers ship new sampling-firmware revisions over the same USB port without disassembling the logger, reducing field service cost.
おすすめ
Computer Peripherals (HID/Keyboard/Storage)
USB keyboards, mice, mass-storage dongles, and HID-class peripherals leverage the PIC24FJ512GB610-I/PT's USB 2.0 Full-Speed OTG with host-or-device mode support, its 85 GPIO for key-matrix scanning, and 512 KB Flash for HID descriptor customization. The hardware AES engine on selected variants secures Bluetooth-HID bridges or encrypted USB drives, and the 32 MHz core provides low-latency HID polling under standard USB 1 ms frames. Pin-compatible PIC24FJ1024GB610 gives 1 MB of Flash for multilingual keyboard firmware and on-device diagnostics.
おすすめ
Human Interface Devices with OTA Update
Field-deployed HIDs that need OTA firmware updates use the PIC24FJ512GB610-I/PT to read images or configuration from a USB host via the OTG port and Live-Update both partitions without downtime. The 512 KB dual-partition Flash means each partition can hold ~256 KB of application, 32 KB of RAM covers USB endpoint buffers plus event queues, and the -40 to +85 °C industrial temperature range handles factory-floor cabinets and outdoor kiosks. Verified Web Data confirms PIC24FJ1024GB610 scales code space to 1024 KB when HMI assets grow beyond 512 KB.
おすすめ
USB OTG Industrial Peripherals (Host Role)
Self-powered industrial peripherals using the PIC24FJ512GB610-I/PT as a USB host (e.g., USB barcode readers, USB-to-UART bridges, USB mass-storage backup modules) leverage the integrated OTG controller without an external PHY. The 85 I/O count exposes UART/SPI/I2C for legacy industrial buses while 32 KB RAM buffers USB bulk transfers, and 512 KB Flash implements vendor-class host stacks plus device-side user logic. The industrial -40 to +85 °C grade and 2.0-3.6 V supply window support 24 V-bus-powered modules after a small front-end DC-DC converter.
おすすめ
Secure Boot/Update Industrial Gateways
Industrial gateways that demand secure boot and encrypted firmware updates benefit from the PIC24FJ512GB610-I/PT's hardware AES engine on select variants, which accelerates encrypted-image validation during Live Update partition swaps. The 512 KB dual-partition Flash supports signed-firmware rollback protection, 32 KB RAM handles secure-boot verification, and the USB OTG port acts as a secure provisioning channel. Pin-compatible PIC24FJ1024GB610 doubles Flash for richer gateway applications like Modbus/TCP to USB bridging with on-device web servers.

設計ノート
Place a 10 µF bulk capacitor and a 0.1 µF ceramic decoupling capacitor adjacent to each VDD/VSS pair on the PIC24FJ512GB610-I/PT. The internal voltage regulator and PLL are noise-sensitive; insufficient decoupling can cause core instability, MPLAB ICD failures, and degraded ADC accuracy. For USB OTG mode add an additional 0.1 µF on the VUSB pin within 5 mm. Estimated: assuming 8 active VDD pins from the TQFP-100 floorplan and 50 mA peak core draw, total bulk capacitance around 22 µF is recommended for industrial environments.
Follow the Explorer 16/32 Development Board reference layout for the TQFP-100 PIM socket when prototyping the PIC24FJ512GB610-I/PT. Keep USB D+/D- traces 90 Ω differential and length-matched within 2 mm, and route the 12 MHz crystal traces short and over a continuous ground plane. The Live Update dual-partition Flash linker script must reserve independent IVT and boot-block regions per partition; failing to do so breaks atomic switchover during OTA updates. Plan partition sizes during code architecture, not retroactively.
Do not exceed 3.6 V on any VDD pin of the PIC24FJ512GB610-I/PT. The dual-partition Live Update feature requires writing to one partition while executing from the other - the linker must place ISRs and the interrupt vector table in execute-in-place (XIP) regions, not the bootstrap copy. USB host-role designs must implement VBUS voltage sensing per OTG spec (HNP/SRP) before pulling D+ high. The AES hardware accelerator is only present on select GB610 variants; verify which GB610 part number has the crypto engine enabled before designing secure-boot flows.
コンプライアンス情報
RoHS compliant per Microchip product page. Industrial temperature grade (-I/) qualified to -40 °C to +85 °C; choose -E/ variant for -40 °C to +125 °C. Not AEC-Q100 qualified - this part is targeting industrial, medical/fitness, computer, and portable applications rather than automotive.
