PIC24EP256GU810-I/PF Présentation
A PIC (Peripheral Interface Controller) microcontroller is a Harvard-architecture RISC device that integrates CPU core, non-volatile program memory, RAM, and a rich set of peripherals into a single IC. The 16-bit PIC24E family extends the original 8-bit PIC line into the high-performance MCU tier, occupying the category position of 16-bit MCU -> microcontroller -> embedded processor -> semiconductor. Compared with 8-bit PIC18F devices, PIC24E adds DSP instructions, larger memory addressing, faster ADC, and direct USB/CAN peripherals, making it suitable for motor control and connectivity.
Key features of the PIC24EP256GU810 include: 60 MIPS execution from a 140 MHz internal oscillator (FOSC = FPLLO/2 path), 256 KB (85.5K x 24) self-programmable flash with ECC, 28 KB SRAM, integrated USB 2.0 full-speed OTG, dual CAN 2.0B modules, 16-bit Sigma-Delta ADC-compatible op-amp front ends, up to 8 PWM channels with 1.04 ns PWM resolution, and 9 UART / 4 SPI / 5 I2C serial channels. The industrial -40C to +85C temperature range is indicated by the "-I" designator and "PF" suffix designates the 100-pin TQFP package.
The PIC24EP256GU810 employs Microchip's nanoWatt XLP ultra-low-power technology, with multiple power modes including Idle, Sleep, and Deep Sleep where current drops to single-digit microamperes, controlled by the Peripheral Pin Select (PPS) subsystem that maps digital functions to any I/O pin. Code is developed in MPLAB X IDE with the MPLAB XC16 compiler; the part is supported by Microchip's Code Configurator plug-in and Harmony framework.
Typical applications include industrial automation (PLC modules, sensor hubs), automotive body and powertrain ECUs (CAN gateways, HVAC controllers), consumer audio with USB streaming, USB-to-CAN bridges, motor-control FOC drives with high-resolution PWM, and medical sensor front ends where the 12-bit ADC and op-amp peripherals simplify analog chain design.
When designing with this part, budget for the 100-pin TQFP land pattern and provide a 3.3 V regulated supply with adequate decoupling on every VDD/VSS pair. Use the PPS system to map peripherals to free I/O pins and leverage the CTMU for capacitive touch or temperature measurement without external components.

Applications typiques
PIC24EP256GU810-I/PF convient pour 6 applications: Industrial CAN-to-USB Gateway, Automotive Body Control ECU, USB-Streaming Audio Consumer Device, PLC Sensor Hub Module, BLDC Motor Control with Field-Oriented Control, Medical Sensor Front End.
Industrial CAN-to-USB Gateway
The PIC24EP256GU810-I/PF's dual CAN 2.0B modules plus integrated USB 2.0 Full-Speed OTG controller make it an ideal single-chip bridge between industrial CAN bus networks and a USB host. At 60 MIPS the PIC24E core runs CANopen, J1939, or DeviceNet stacks at full bus load while servicing USB CDC or vendor-class traffic. The 28 KB SRAM holds CAN receive buffers plus USB endpoint descriptors, eliminating the need for external memory. Place the IC with a 3.3 V LDO, ESD-protected CAN transceiver (e.g., MCP2558FD), and USB type-B connector; the PIC24E PPS peripheral pin select system remaps UART, SPI, or CAN signals to free I/O for layout flexibility.
Recommandé
Automotive Body Control ECU
The PIC24EP256GU810-I/PF drives body and convenience ECUs (HVAC, lighting controllers, door modules) where dual CAN bus nodes talk to a central gateway. Operating from -40C to +85C industrial range (extendable via -E/PF to +125C), 60 MIPS execution runs AUTOSAR-friendly CAN stacks plus peripheral handling. The 8 high-speed PWM channels with 1.04 ns resolution drive LED matrices and small BLDC fans; the 12-bit ADC with integrated op-amps reads temperature, current, and potentiometer inputs without external signal conditioning. The 256 KB flash stores bootloader + application, supporting OTA firmware updates over CAN.
Recommandé
USB-Streaming Audio Consumer Device
USB audio streaming devices such as USB DACs, headphone adapters, and conference speakers use the PIC24EP256GU810-I/PF as a USB-2.0-Full-Speed device that delivers 24-bit audio over isochronous endpoints. The PIC24E core handles USB protocol plus I2S/SPDIF output to an external DAC, with DMA channels freeing the CPU from sample-rate conversions. The 60 MIPS headroom also runs DSP-style filters (biquads, crossovers) at zero external DSP cost. The 100-pin TQFP footprint supports the 9 UART / 4 SPI / 5 I2C peripheral mix needed for buttons, displays, and codec control simultaneously.
Recommandé
PLC Sensor Hub Module
Programmable Logic Controller (PLC) analog/digital input modules use the PIC24EP256GU810-I/PF to multiplex up to 16 analog channels (12-bit, 500 ksps) and 30+ digital I/O into a CAN or RS-485 backplane. The integrated DMA moves conversion data without CPU intervention, freeing 60 MIPS for IEC 61131-style task execution in micro-PLC firmware. The 256 KB flash holds the ladder-logic runtime plus module configuration, while 28 KB SRAM buffers scan data. The 100-pin TQFP package exposes ample GPIO for optocoupler-isolated inputs and relay outputs.
Recommandé
BLDC Motor Control with Field-Oriented Control
BLDC and PMSM motor drives requiring field-oriented control (FOC) benefit from the PIC24EP256GU810-I/PF's 8-channel high-resolution PWM (1.04 ns edge placement) and dual 12-bit ADC with synchronized sampling. The PIC24E core runs FOC at 60 MIPS with sufficient headroom for sinusoidal commutation, sensorless BEMF detection, and current-loop control at 20 kHz PWM frequency. Quadrature encoder interface and Hall-sensor inputs are remapped via PPS. The 256 KB flash stores FOC libraries plus customer parameters; 28 KB SRAM holds observer state and current d/q components. For higher-performance DSP-style FOC, migrate to dsPIC33EP256GM604-I/PF (same package, adds 70 MIPS DSP engine).
Recommandé
Medical Sensor Front End
Medical-grade sensor front ends (pulse oximeters, bedside monitors, infusion pump control boards) leverage the PIC24EP256GU810-I/PF's 12-bit ADC with integrated op-amp front ends, USB OTG for data upload, and CAN connectivity for bedside-network integration. The PIC24E nanoWatt XLP technology keeps quiescent current low for battery-powered designs, while the 256 KB flash stores sensor calibration tables and patient-data buffers. The -40C to +85C industrial temperature range supports clinical and home-health use cases; pair with the PIC24EP256GU810-E/PF (extended temperature) for portable diagnostic devices.

Principaux différenciateurs
- Dual CAN 2.0B + USB OTG in a single 100-pin MCU (vs PIC24EP256GP206-I/PT)
- Higher flash and RAM headroom for future firmware growth (vs PIC24EP128MC206-E/PT)
- Industrial -40C to +85C operation with extensive peripherals (vs PIC24FJ256GB110)
Notes de conception
Power the PIC24EP256GU810-I/PF from a low-noise 3.3 V LDO (MCP1700 or MCP1755S) rated for at least 100 mA continuous plus transient headroom for USB enumeration. Place a 100 nF decoupling capacitor as close as possible to every VDD/VSS pair (there are 5 VDD pins and 5 VSS pins on this 100-pin TQFP). For USB bus-powered designs, add a 4.7 uF bulk capacitor near the VBUS pin to handle inrush current during host enumeration. Estimated: the MCU core draws ~40 mA active at 60 MIPS and the USB module adds ~10 mA, so budget 60-70 mA peak.
Route the 100-pin TQFP land pattern with 0.5 mm pitch and 1.6 mm pad length per Microchip app note AN1258. Use a 4-layer PCB with a dedicated ground plane under the IC; do not route signals beneath the package thermal pad area if present. Keep the 12 MHz or 8 MHz crystal traces (OSCI/OSCO) under 5 mm, surrounded by ground pour on both sides, and place crystal load capacitors within 2 mm of the IC pins. Keep USB D+/D- traces matched within 0.5 mm and 90 ohm differential impedance per USB 2.0 spec.
Avoid these common PIC24E design mistakes: (1) Do not drive any I/O pin above VDD + 0.3 V; only specific 5 V tolerant pins (Vbus sense, MCLR if configured) accept higher voltages. (2) When using USB OTG, ensure the ID pin has the correct 15K pull-down for host role detection; floating ID prevents role negotiation. (3) Peripheral Pin Select (PPS) remapping must be unlocked via __builtin_write_OSCCONL before changes - lock it back to prevent accidental remapping during interrupts. (4) The 256 KB flash has ECC enabled by default; spurious ECC errors during development typically indicate VDD brown-out - add power-on-reset circuitry.
The PIC24EP256GU810-I/PF in TQFP-100 has a typical theta_JA of approximately 35-40 C/W on a 4-layer PCB with a 2 oz copper inner ground plane. At maximum active load (60 MIPS, all peripherals enabled) the device dissipates ~250 mW, resulting in a ~10 C junction rise above ambient. Estimated: at 85 C ambient the junction reaches ~95 C, well within the 125 C operating maximum. For sealed enclosures with no airflow, derate the clock to 40 MIPS or add thermal vias beneath the exposed pad (if present on this TQFP variant).
For CAN bus designs, place the MCP2558FD or similar transceiver within 20 mm of the PIC24E C1RX/C1TX pins and add 120 ohm split termination at each end of the bus. For USB 2.0 Full-Speed, add 15K pull-down on D- for device mode (default per USB spec) and 1.5K pull-up on D+ when device asserts connection. Both CAN and USB lines benefit from common-mode chokes (DLW21SN or equivalent) if the design must pass industrial EMC tests such as IEC 61000-4-2 for ESD or IEC 61000-4-4 for EFT.
