DSPIC33EP64MC502-E/MM 概要
A Digital Signal Controller combines the compute capability of a microcontroller with DSP instruction acceleration in a single core. In the power-management hierarchy, the dsPIC33EP sits between general-purpose MCUs and dedicated DSPs, offering a 16-bit modified Harvard architecture with DSP multiply-accumulate instructions, making it a preferred choice for embedded control systems that require both real-time control loops and signal processing.
Key features include a 60 MIPS dsPIC33E core, high-speed Motor Control PWM (MCPWM) with complementary outputs and dead-time insertion, a Quadrature Encoder Interface (QEI) for position feedback, 4 DMA channels, and multiple serial peripherals (UART, SPI, I2C). The -E suffix denotes AEC-Q100 automotive-grade qualification with operation to +125C, per distributor parametric data.
The modified Harvard architecture supports single-cycle MAC operations with dual data fetch, enabling efficient execution of PI and PID control loops, field-oriented control (FOC) transforms, and Clarke/Park calculations for brushless DC and permanent magnet motor drives. The high-speed PWM peripherals synchronize with the ADC for precise current sampling at the PWM center.
Typical applications include brushless DC and PMSM motor control, digital power supplies, automotive pump and fan controllers, and industrial drives requiring extended temperature operation.
Design consideration: at 60 MIPS the core requires a 3.0V to 3.6V supply; ensure decoupling and consider that the QFN exposed pad must be soldered to a grounded thermal pad for reliable operation across the full -40C to +125C range.

主な用途
DSPIC33EP64MC502-E/MM の用途: 6 件s: Brushless DC Motor Control, Automotive Pump and Fan Controllers, Digital Power Conversion, Industrial Drives and Robotics, Sensor Signal Processing, Embedded Control and IoT Nodes.
Brushless DC Motor Control
The DSPIC33EP64MC502-E/MM fits BLDC and PMSM drives because its high-speed MCPWM module generates complementary PWM pairs with programmable dead-time, while the 60 MIPS core executes field-oriented control with single-cycle MAC instructions. The QEI module decodes incremental encoder feedback for closed-loop position control. Typical topology: three half-bridges driven by the MCPWM, with phase currents sampled by the internal ADC synchronized to the PWM center for ripple-free readings. The -E grade (-40C to +125C) allows mounting near hot motor windings or under-hood locations.
おすすめ
Automotive Pump and Fan Controllers
AEC-Q100 qualification and the extended -40C to +125C temperature range make the DSPIC33EP64MC502-E/MM appropriate for automotive auxiliary drives such as coolant pumps, radiator fans, and actuator motors. The MCPWM with fault inputs enables fast shutdown on overcurrent events, while UART/SPI/I2C provide LIN/CAN gateway connectivity via external transceivers. The 64 KB Flash accommodates diagnostic routines, failure counters, and bootloaders required in automotive software architectures. On-board DMA offloads ADC sampling from the CPU, preserving loop bandwidth at high PWM frequencies.
おすすめ
Digital Power Conversion
The dsPIC33EP64MC502 supports digital SMPS topologies: the MCPWM offers center-aligned complementary outputs for LLC, half-bridge, and boost converters, with ADC triggering at PWM midpoint to sample output current at minimal ripple. The 60 MIPS DSP core runs proportional-integral compensation loops at tens of kHz update rates, and DMA moves ADC results without CPU intervention. The 3.0V to 3.6V supply simplifies integration into systems with standard 3.3V logic rails, and the extended temperature grade suits power supplies operating in hot enclosures.
おすすめ
Industrial Drives and Robotics
In industrial servo and stepper drives, the QEI interface handles encoder feedback while MCPWM drives power stages; the 60 MIPS core performs trajectory generation and control-loop math concurrently. SPI and UART interfaces connect to supervisory PLCs, and I2C supports configuration EEPROM and sensors. The 64 KB Flash stores motion profiles and multi-axis coordination code, while 4 DMA channels keep serial data streaming deterministic. The 28-QFN 6x6 mm footprint conserves PCB area in compact drive modules operating in hot industrial cabinets.
おすすめ
Sensor Signal Processing
The DSP instruction set (single-cycle MAC, dual operand fetch) makes the DSPIC33EP64MC502 effective for sensor front-ends: filtering vibration data, demodulating signals, or computing RMS values in power meters. The internal ADC samples analog inputs (AN0-AN5 available on the 28-pin device), and DSP routines apply FIR/IIR filters efficiently. The -E temperature grade allows deployment in outdoor metering and HVAC sensing equipment where ambient temperatures reach +85C to +105C, while the QFN package minimizes board space in dense sensor nodes.
おすすめ
Embedded Control and IoT Nodes
As a general 16-bit embedded controller, the DSPIC33EP64MC502-E/MM combines MCU peripherals (UART, SPI, I2C, timers, PPS) with DSP headroom for local analytics. ECAN/UART bridges to wireless modules, SPI to flash or displays, and the peripheral pin select architecture flexibly routes functions to available pins on the 28-pin device. The extended temperature range supports outdoor and industrial IoT deployments, while in-circuit programming enables field firmware updates through the ICSP interface or a custom bootloader.

設計ノート
The QFN exposed pad (EP) on pin 28 is the primary thermal and ground path. Solder it to a grounded PCB pad with a 4x4 via array (0.3 mm vias) connecting to internal ground planes. Without a solid EP connection, thermal resistance rises substantially and full -40C to +125C extended-grade operation at 60 MIPS cannot be guaranteed. Follow Microchip QFN layout guidelines in the family datasheet DS70000657J.
Supply 3.0V to 3.6V (nominal 3.3V) with 0.1 uF ceramic decoupling at each VDD pin plus 4.7-10 uF bulk. Place decoupling within 2 mm of the QFN power pins. PWM switching edges couple through the ground return; use a solid ground plane and keep analog VREF traces away from PWM pins. For automotive rails, add an LDO or buck front-end plus reverse-polarity and load-dump protection.
On 28-pin variants, peripheral pin select (PPS) routing is constrained: some pins are analog-only at power-up (AN0-AN5), and I2C pins 12-13 are fixed-function. Verify pin availability for simultaneous MCPWM, QEI, and UART use before layout - budget is tight on the MC502. Also confirm the -E grade requirement early: switching to -I/MM later saves cost only if ambient never exceeds +85C.
