PIC24EP512GU814-I/PL 概要
A microcontroller (MCU) is an integrated circuit that combines a processor core, program memory (Flash), data memory (RAM), and a rich set of peripherals into a single chip. The PIC24E family sits in Microchip's 16-bit DSC (Digital Signal Controller) hierarchy: 8-bit PIC16/PIC18 -> 16-bit PIC24 -> 16-bit dsPIC33 -> 32-bit PIC32, offering a balance of deterministic performance, low power, and DSP-class signal processing in cost-sensitive embedded designs.
Key features of the PIC24EP512GU814 include integrated Full-Speed USB 2.0 (host/device/OTG), two independent CAN 2.0B controllers, a 12-bit ADC with up to 1.1 Msps conversion rate, motor-control PWMs, and a Peripheral Pin Select (PPS) subsystem that allows digital peripheral I/O mapping to a wide range of physical pins. The 70 MIPS core gives it strong DSP-class performance for filtering and control loops. The 144-pin LQFP (20x20x1.4 mm) package exposes a large number of I/O and analog channels.
Architecturally, the PIC24EP core uses a 24-bit instruction word with 16-bit data paths, single-cycle hardware MAC, hardware DO/DO# loops, zero-overhead looping, and tightly-coupled interrupt logic. This makes it well-suited for closed-loop motor control, power conversion, and high-throughput serial protocols running concurrently.
Typical applications include industrial automation (PLC, sensor hubs, motor drives), automotive body and chassis ECUs (CAN-connected nodes), USB peripherals (data loggers, instrumentation, Human Interface Devices), medical instrumentation, and embedded graphical HMI panels. The USB + Dual-CAN combination is particularly attractive for gateway and bridge designs.
When designing with this part, plan the PPS remapping table early so digital peripherals land on the desired pins without conflicts, and ensure the 3.3 V rail provides sufficient decoupling near each VDD/VSS pair. The 144-LQFP footprint requires careful escape routing and 0.4 mm pitch traces.
This page synthesizes real-time distributor pricing, drop-in same-package alternatives, and practical design notes curated for engineers evaluating the PIC24EP512GU814 family for new designs or as a substitute on an existing 144-pin LQFP layout.

主な用途
PIC24EP512GU814-I/PL の用途: 7 件s: Industrial CAN-to-USB Gateway, Automotive Body Control Module, USB Data Acquisition Instrument, Motor Control / Variable Frequency Drive, Medical Patient Monitoring Device, Graphical HMI / Operator Panel, Smart Sensor Hub / IoT Edge Node.
Industrial CAN-to-USB Gateway
The PIC24EP512GU814-I/PL's integrated dual CAN 2.0B plus USB 2.0 Full-Speed OTG is the ideal bridge for an industrial gateway node that streams two CAN buses (e.g., CANopen + J1939) to a host PC. The 70 MIPS PIC24E core runs a TCP-to-CAN stack and CANopenSDO server concurrently, while 512 KB Flash hosts both the application and the USB-CDC class driver. PPS remapping keeps the CAN and UART signals cleanly separated. Designers should allocate DMA channel 0 for CAN1 RX to offload message handling from the CPU at high bus loads.
おすすめ
Automotive Body Control Module
For body and chassis ECUs requiring dual CAN connectivity, the PIC24EP512GU814-I/PL drives window, mirror, lighting, and sensor subsystems while communicating with the vehicle's powertrain and body CAN buses at 500 kbps and 125 kbps respectively. Its 12-bit 1.1 Msps ADC supports multiple sensor inputs, and the 52 KB RAM holds enough buffer for CAN message routing without dropping frames. PPS simplifies board layout by reassigning UART and SPI pins without remapping the PCB. Industrial-grade -40 to +85 °C is sufficient for cabin-mounted modules.
おすすめ
USB Data Acquisition Instrument
A USB-connected bench-top data logger uses the PIC24EP512GU814-I/PL to sample multiple analog channels via the 12-bit ADC at up to 1.1 Msps, then streams the data to a host PC over USB 2.0 Full-Speed. The 512 KB Flash stores calibration constants, lookup tables, and a custom USB class driver, while 52 KB RAM buffers acquisition bursts. The dedicated DMA engine moves ADC results without CPU intervention, leaving MIPS free for signal conditioning. Industrial temperature ensures stable operation in laboratory environments.
おすすめ
Motor Control / Variable Frequency Drive
Three-phase BLDC or PMSM motor control up to several hundred watts is well served by the PIC24EP512GU814-I/PL thanks to its dedicated motor-control PWM module with complementary outputs and programmable dead time. The 70 MIPS core runs a Field-Oriented Control loop at 20 kHz, and the 12-bit ADC samples phase currents synchronously to the PWM. Dual CAN allows integration into a multi-axis industrial drive network. The 144-LQFP provides ample GPIO for Hall/encoder inputs and fault protection signals.
おすすめ
Medical Patient Monitoring Device
Battery-powered patient monitors for vital-signs tracking leverage the PIC24EP512GU814-I/PL's USB device port for charging and data transfer to clinical workstations. The 70 MIPS core processes ECG and SpO2 waveform filtering, while the 12-bit ADC captures front-end analog signals at the necessary sample rate. 512 KB Flash is large enough to host a real-time OS plus a Bluetooth HCI stack if paired with an external radio. Industrial temperature range and 3.3 V operation simplify IEC 60601-1 isolation design.
おすすめ
Graphical HMI / Operator Panel
Mid-range operator panels with TFT LCDs and touch interfaces use the PIC24EP512GU814-I/PL to drive a parallel display interface, manage touch sensing via the ADC, and expose CAN and USB to a host controller or PLC. The PIC24EP parallel master port and 8-bit PMP peripherals map easily to standard 480x272 TFT displays. 52 KB RAM holds double-buffered frame data, and 512 KB Flash stores fonts, menus, and graphics assets. Industrial temperature supports factory-floor deployment.
おすすめ
Smart Sensor Hub / IoT Edge Node
An industrial IoT edge node aggregates multiple sensor inputs (temperature, pressure, vibration) over I2C/SPI and forwards them to a cloud gateway via the integrated USB or CAN. The PIC24EP512GU814-I/PL's DMA-driven ADC scan mode reads 8-16 analog channels efficiently while the CPU runs local filtering and anomaly detection. PPS lets the designer re-route UART, SPI, and I2C peripherals to any convenient pin, simplifying a tight 144-LQFP layout. Industrial temperature enables outdoor and factory-cabinet deployment.

設計ノート
Power architecture for the PIC24EP512GU814-I/PL should provide a clean 3.3 V rail with under 50 mV peak-to-peak ripple. Place a 4.7 µF bulk capacitor close to the main VDD pin group, then 100 nF X7R ceramic capacitors at each VDD/VSS pair as listed in the pinout. The AVDD/AVSS analog domain must be filtered with a ferrite bead or small L-C network from the digital 3.3 V to keep ADC sampling noise below the 12-bit LSB. Add a 4.7 µF + 100 nF pair on VREF+ to stabilize the ADC reference.
The 144-LQFP at 0.4 mm pitch requires escape routing on a 4-layer PCB with micro-vias under the pads. Use 0.2 mm traces between pins and route the USB D+/D- pair as a 90 Ω differential with length matching within 150 mil. The crystal traces between OSCI/OSCO and the load capacitors should be short and symmetric, with a ground guard ring to keep digital switching noise from coupling in. Keep the analog ANxx traces away from PWM outputs to reduce ADC crosstalk.
Three common pitfalls on PIC24EP designs: (1) Forgetting to unlock the Peripheral Pin Select (PPS) registers by writing the IOLOCK unlock sequence - peripherals will not map to pins otherwise. (2) Configuring the ADC channel scan without disabling digital input on analog pins (use the ANSx register) - this injects digital switching noise into conversions. (3) Using the PLL with the wrong input divider - the PIC24E PLL requires specific VCO and post-divider combinations per the datasheet's oscillator configuration table to achieve 70 MIPS reliably.
Estimated: At the maximum 70 MIPS with all peripherals active, core current draw is approximately 80 mA. With a 144-LQFP thermal resistance of approximately 50 °C/W (typical 4-layer JEDEC test board), full-load temperature rise is around 4 °C above ambient - well within industrial limits. The USB driver adds up to 25 mA when active. Designers in fully sealed enclosures should still verify with the manufacturer IBIS or thermal model for their specific board stackup.
When routing USB D+/D-, target 90 Ω differential impedance and keep the pair length-matched to within 150 mil (3.8 mm). Place the 15 kΩ pull-down on D- and the 1.5 kΩ pull-up on D+ only after firmware enables USB. For CAN bus signals, add a 120 Ω termination resistor at each end of the bus and route CANTX/CANRX with a short stub to a CAN transceiver such as the MCP2551 or ATA6563. The 100-pin Plug-In Module (PIM) adapter notes from Microchip show that several 144-LQFP signals are multiplexed onto the 100-pin PIM socket via zero-ohm resistors.
