PIC24EP256GU810-I/PT 개요
A microcontroller (MCU) is a single-chip computer containing a CPU, program memory, data memory, and programmable peripherals. The PIC24E family uses a 16-bit modified-Harvard RISC architecture with a 24-bit instruction word, placing it above 8-bit MCUs such as PIC16/PIC18 in code density and arithmetic throughput while remaining simpler than 32-bit Cortex-M parts in toolchain cost and interrupt model. The 24EP 'GU' sub-family further extends this with USB 2.0 Full-Speed On-The-Go and dual CAN, positioning it for connected industrial and embedded applications.
Key features include 256 KB (85.5K x 24) flash, 28 KB RAM, 4 KB EEPROM emulation area, 8-channel DMA into 16 KB dual-port SRAM, USB 2.0 Full-Speed OTG with integrated PHY, two CAN 2.0B modules, six UART, four SPI, five I2C, twelve 16-bit timers, twelve PWM outputs, four IC/OC, two 10-bit ADC and one 12-bit ADC at 1.1 Msps, two analog comparators with op-amp mode, and a CTMU for capacitive touch. The 100-pin TQFP (PT) exposes 85 I/O pins and supports industrial-grade -40C to +85C operation.
Architecturally, the PIC24EP uses a 5-stage pipeline with single-cycle 16-bit MAC, hardware multiply/divide, deterministic interrupt latency, and a wide peripheral bus. The high-speed ADC and CTMU combination enables precise sensor acquisition, while the dual CAN and USB OTG allow simultaneous industrial-network bridging and USB device/host connectivity. The package is pin-compatible with other PIC24EP family members in the 100-pin TQFP.
Typical applications include industrial automation controllers, CAN node bridges with USB diagnostics, USB-based data acquisition devices, motor-control and inverter driver boards, BLDC/PMSM drive stages with field-oriented control, USB human-interface devices, multi-protocol IoT gateways, and medical instrumentation with USB data export. The 256 KB flash accommodates real-time operating systems plus application stacks.
When designing with this MCU, verify that the 3.0-3.6 V supply is decoupled close to every VDDCORE/VDD pin and that the VUSB pin is supplied with a clean 3.3 V before USB enumeration. Use the on-chip LDO or an external 1.8 V regulator for the core and ensure the USB D+/D- traces are 90 ohm differential and routed over a continuous ground plane.

일반적인 애플리케이션
PIC24EP256GU810-I/PT 적합 용도: 6 애플리케이션s: Industrial CAN Node with USB Diagnostics, USB Data Acquisition Module, BLDC / PMSM Motor Drive Controller, USB Human Interface Device (HID), Multi-Protocol IoT Gateway Edge Node, Medical Instrumentation with USB Export.
Industrial CAN Node with USB Diagnostics
The PIC24EP256GU810-I/PT is well suited as a CAN node controller with simultaneous USB diagnostics, because it integrates dual CAN 2.0B plus USB 2.0 Full-Speed OTG in one 16-bit MCU. Its 60 MIPS core runs CANopen or J1939 stacks while exposing the same node over USB for service tooling without an external bridge chip. The 28 KB RAM is sufficient for CAN message buffers plus a CDC/USB device stack, and the 256 KB flash accommodates the protocol library plus custom application code.
추천
USB Data Acquisition Module
The PIC24EP256GU810-I/PT works well as the heart of a USB-tethered data acquisition module, owing to its 12-bit 1.1 Msps ADC plus 10-bit ADCs and USB Full-Speed interface. The 12-bit ADC provides 1.1 Msps throughput across 16 analog inputs, supporting multi-channel sensor sampling at kHz rates. With USB OTG onboard, the module can present itself as a CDC device for direct streaming to a host PC, eliminating an external bridge IC.
추천
BLDC / PMSM Motor Drive Controller
The PIC24EP256GU810-I/PT can drive 3-phase BLDC or PMSM motors by using its 12 PWM outputs, three analog comparators with op-amp mode, and the CTMU for current sensing timing. The 60 MIPS PIC24E core executes field-oriented-control loops within microseconds, while 85 I/O pins allow parallel control of multiple motor phases, gate drivers, and feedback sensors. The 100-pin TQFP exposes enough analog channels for triple-shunt current sensing plus DC-bus voltage monitoring.
추천
USB Human Interface Device (HID)
The PIC24EP256GU810-I/PT is a strong fit for USB HID-class devices such as custom keypads, control surfaces, and industrial pendants because the USB Full-Speed controller and on-chip PHY remove the need for an external bridge. The 256 KB flash stores USB HID stacks plus application logic, while 85 I/O pins accommodate large switch-matrix or encoder inputs. With 60 MIPS, latency remains below USB 1 ms polling boundaries even with heavy switch debouncing.
추천
Multi-Protocol IoT Gateway Edge Node
The PIC24EP256GU810-I/PT works well as an edge node in IoT gateways because dual CAN, USB OTG, six UARTs, four SPIs, and five I2Cs allow simultaneous bridging between fieldbus, sensor, and host networks. Its 60 MIPS core runs message-routing logic with deterministic interrupt latency, while 256 KB flash holds multi-protocol stacks plus custom routing rules. The 28 KB RAM accommodates message buffers for each protocol, and DMA offloads data movement from the CPU.
추천
Medical Instrumentation with USB Export
The PIC24EP256GU810-I/PT fits medical instrumentation such as patient monitors or diagnostic peripherals that require clean analog sampling and USB data export to a host PC. Its 12-bit 1.1 Msps ADC captures biosignals with adequate resolution, while USB OTG streams waveform data in real time. The industrial -40C to +85C temperature rating supports clinical environments, and 256 KB flash stores USB CDC stacks plus patient-data buffers.

설계 노트
The PIC24EP256GU810-I/PT requires a clean 3.0 V to 3.6 V supply on every VDD pin with 100 nF ceramic decoupling placed within 5 mm of each pin, plus a bulk 4.7 uF tantalum or ceramic near the package. The internal LDO generates 1.8 V for the core from VDD; ensure VDD droop never drops below 3.0 V during USB transmit bursts to avoid enumeration failures.
Route USB D+ and D- as a 90 ohm differential pair over a continuous ground plane with length matching within 150 mil. Place the VUSB 3.3 V supply and a decoupling capacitor within 5 mm of the USB pins. Maintain a guard ground around the crystal oscillator traces to minimize EMI coupling into the PLL that drives the 140 MHz core.
Do not leave the MCLR pin floating - tie it to VDD through a 10 kohm pull-up or leave it unused only if the internal pull-up is enabled in configuration bits. Set the JTAGEN configuration bit to DISABLED when using those pins as GPIO, since JTAG defaults to enabled and may otherwise consume four I/O pins unintentionally. Configure the POSCMD/HFNOSC settings before applying power if a non-default oscillator is needed.
