PIC24EP256GU810-E/PF - 16-bit 60 MIPS MCU 256KB Flash USB CAN TQFP-100
MPN: PIC24EP256GU810-E/PF ✓ نشطPIC24EP256GU810-E/PF نظرة عامة
A 16-bit microcontroller (MCU) is a microprocessor core that operates on 16-bit-wide data paths, offering higher code density and arithmetic precision than 8-bit cores while remaining simpler and more deterministic than 32-bit Cortex-M parts. PIC24EP devices sit in the wider taxonomy: microcontroller -> embedded MCU -> 16-bit MCU -> DSC (Digital Signal Controller). They are commonly used where DSP-class arithmetic, CAN automotive networking, and USB host/device connectivity must coexist on one chip.
Key features include a high-speed 70 MIPS PIC24E core with single-cycle MAC, a 10/12-bit ADC with up to 1.1 Msps conversion rate, motor-control PWMs with dedicated time bases, and dual analog comparators. The USB OTG transceiver plus dual CAN controllers make this part a strong fit for automotive instrument clusters, body-control modules, and industrial CAN nodes.
The architecture combines a modified Harvard bus with DSP extensions, supporting fractional arithmetic and zero-overhead loops. The 256 KB Flash is partitioned for live update via dual-partition boot, and the on-chip 28 KB RAM is sufficient for USB device stacks plus a CAN application buffer simultaneously. The instruction set is upward-compatible with PIC24F/dsPIC33 families, easing code reuse.
Typical applications include automotive body controllers and HVAC modules, industrial CAN gateways, USB-to-CAN bridges, motor-control BLDC/PMSM drives, and small graphical HMI panels. The wide I/O count and dual CAN also suit battery management systems that need multiple isolated CAN channels.
Designers should budget decoupling carefully: place 100 nF plus 10 µF ceramics within 5 mm of every VDDCORE/VDD pair, and route the dual CAN bus with a 120 Ω termination and TVS protection. The USB bus must use a 90 Ω differential impedance controlled region.

التطبيقات النموذجية
PIC24EP256GU810-E/PF مناسب لـ 7 التطبيقs: Automotive Body Control Module, Industrial CAN Gateway / Bridge, USB-to-CAN Diagnostic Adapter, BLDC / PMSM Motor Controller, Automotive HVAC Control Module, Battery Management System (BMS) Slave, Small Graphical HMI Panel.
Automotive Body Control Module
The PIC24EP256GU810-E/PF fits automotive BCM designs because of its AEC-Q100 qualification, -40C to +125C operating range, and dual CAN 2.0B controllers. With 83 I/O pins the MCU can drive door-lock, lighting, and wiper loads directly through FET pre-drivers, while the 256 KB Flash stores the CAN J1939 stack plus body-control state machine. Dual CAN enables gateway routing between powertrain CAN-C and body CAN-B buses in real time. The 70 MIPS PIC24E core runs LIN scheduling and PWM dimming concurrently with deterministic interrupt latency, eliminating the need for an external supervisor.

Industrial CAN Gateway / Bridge
In an industrial CAN-to-CAN bridge the PIC24EP256GU810-E/PF provides two independent CAN 2.0B controllers that can run at different bus speeds and forward messages with hardware acceptance filters. The 28 KB RAM buffers burst traffic during protocol translation, and the 256 KB Flash holds Modbus-to-CAN mapping firmware. The USB OTG port is useful for field diagnostics, allowing a service technician to plug in a laptop and read CAN traffic. Industrial temperature variants (-I suffix) cover -40C to +85C machinery enclosures without AEC-Q100 cost.

USB-to-CAN Diagnostic Adapter
For a USB-to-CAN PC-side diagnostic tool the PIC24EP256GU810-E/PF combines USB 2.0 Full-Speed OTG with a CAN 2.0B controller in a single chip, eliminating external PHYs. The 70 MIPS core processes the USB CDC protocol alongside the CAN handler, while 28 KB RAM hosts both stacks simultaneously. The automotive -E grade allows the same design to be deployed in vehicle diagnostics (OBD-II passthrough) without re-qualification. Programming follows the standard Microchip MLA USB device library and CAN driver.
موصى به
BLDC / PMSM Motor Controller
The PIC24EP256GU810-E/PF drives sensorless or hall-sensor BLDC motors using its dedicated motor-control PWM with complementary outputs and programmable dead time. The high-speed 10/12-bit ADC at up to 1.1 Msps samples phase currents synchronously to the PWM cycle, while the dual analog comparators trigger hardware fault shutdown. 256 KB Flash holds field-oriented-control (FOC) firmware with sin/cos lookup tables, and 28 KB RAM is sufficient for two concurrent control loops (torque + speed).
موصى به
Automotive HVAC Control Module
HVAC modules need reliable CAN communication, multiple temperature/humidity sensor inputs, and PWM fan/blower control - all within the PIC24EP256GU810-E/PF envelope. The 12-bit ADC reads up to 16 analog channels for cabin and evaporator sensors; the dual comparators handle over-temperature shutdown. The AEC-Q100 grade and -40C to +125C range suit under-dash mounting. The 83 I/O pins drive the LCD segment driver and rotary encoder without external GPIO expanders.
موصى به
Battery Management System (BMS) Slave
As a CAN-connected BMS slave the PIC24EP256GU810-E/PF monitors individual cell voltages through its 12-bit ADC while communicating with the master BMS over an isolated CAN link. The 256 KB Flash stores cell-balancing tables and state-of-charge algorithms, and 28 KB RAM buffers telemetry packets between CAN transmissions. AEC-Q100 qualification is essential for under-the-hood automotive battery packs. The dual CAN ports allow direct tie-in to vehicle CAN-C plus an auxiliary service CAN.
موصى به
Small Graphical HMI Panel
For a 3.5-inch color TFT HMI panel the PIC24EP256GU810-E/PF drives the display through its EPMP (Enhanced Parallel Master Port) and provides USB for firmware update plus CAN for fieldbus connectivity. The 70 MIPS core renders buttons and basic icons in software without an external graphics controller. 256 KB Flash holds the graphical asset library; 28 KB RAM serves as the frame buffer for small monochrome or low-color UIs. The 83 I/O pins connect directly to the touch controller and backlight driver.

ملاحظات التصميم
Decouple every VDD/VSS pair with a 100 nF X7R ceramic placed within 5 mm of the pin, plus a bulk 10 µF tantalum or polymer capacitor at the regulator output. The PIC24EP256GU810-E/PF has multiple VDD/AVDD pairs that must all be powered; failure to tie AVSS to VSS causes erratic ADC readings. Sequence VDD before AVSS by no more than 100 ms to avoid latch-up at cold-start in automotive environments.
Route the USB D+/D- pair as a 90 Ω differential-controlled-impedance trace with length matching within 150 mil. Keep the trace away from switching nodes (PWM outputs, CAN bus). Route the dual CAN bus with 120 Ω characteristic impedance and place a split termination (60 Ω + 60 Ω with 4.7 nF to ground) at each end to suppress common-mode ringing in automotive harnesses.
The 100-pin TQFP package has a typical θJA of approximately 45 °C/W on a 4-layer JEDEC test PCB. At full 70 MIPS operation the core dissipates ~250 mW; in a sealed automotive enclosure at 85 °C ambient this yields a junction temperature of ~96 °C, comfortably below the 150 °C maximum. For continuous -40 °C to +125 °C operation add a thermal via array under the exposed pad (this TQFP-100 has no thermal pad - ensure 1 oz copper pours on top and inner layers).
The PIC24EP256GU810-E/PF shared-pin architecture maps C1TX/C2TX and USB D+/D- onto the same PORTG pins as GPIO. When the peripheral is disabled, the pins revert to GPIO - ensure firmware initializes the PPS (Peripheral Pin Select) registers before configuring GPIO direction. Failure to do so can cause unintended bus contention when the firmware boots in development mode.
Do not connect the MCLR pin directly to VDD without a pull-up; the device requires the MCLR pulse to enter ICSP programming mode. Always include a 10 kΩ pull-up and 100 nF decoupling on MCLR. The 83 I/O pins exceed 80 mA total source/sink budget - sum all GPIO loads and verify against the data sheet's VOH/IOH curves before adding LED arrays or relay drivers.
