Applications
The DSPIC33EP64MC202-I/SS is designed for digital motor control applications such as BLDC and PMSM field-oriented control where its dedicated PWM engine and 12-bit ADC deliver the real-time feedback loops required at up to 70 MIPS. It is also used in power conversion designs including PFC boost converters and DC-DC regulators that require precise duty-cycle control at high switching frequencies. The 28-pin SSOP form factor makes it a practical choice for compact industrial servo drives and appliance motor controllers.

Frequently Asked Questions
What is the maximum clock frequency and instruction throughput of the DSPIC33EP64MC202-I/SS?
The DSPIC33EP64MC202-I/SS runs at a maximum oscillator frequency of 140 MHz, yielding up to 70 MIPS of instruction throughput on its 16-bit modified Harvard architecture. This performance level is sufficient to close 20 kHz FOC current loops and run PID controllers for BLDC motor drives in real time.
How much program memory does DSPIC33EP64MC202-I/SS provide, and how does that compare to DSPIC33EP32MC202 for larger firmware projects?
The DSPIC33EP64MC202-I/SS includes 64 kB of on-chip Flash program memory, which is double the 32 kB available on the DSPIC33EP32MC202. The additional 32 kB is valuable when firmware includes multiple motor-control profiles, USB stacks, or communication protocol libraries that push the 32 kB boundary.
Which motor-control designs can use the DSPIC33EP64MC202-I/SS in a 28-pin SSOP footprint?
The 28-pin SSOP package hosts the motor-control PWM outputs, 12-bit ADC inputs, and DMA channels needed for single-axis BLDC, PMSM, and stepper motor drives. Designers can implement a 3-phase inverter gate-drive interface with current-sense feedback using as few as 6 PWM outputs and 3 ADC channels within the 28-pin footprint.
Does the DSPIC33EP64MC202-I/SS support DMA, and what benefit does that provide in data-acquisition applications?
Yes, the DSPIC33EP64MC202-I/SS includes DMA channels that transfer ADC conversion results directly to RAM without CPU intervention. In a 12-bit ADC application sampling at 1 Msps across 8 channels, DMA reduces CPU overhead by over 90%, freeing cycles for PID and DSP filter execution in motor-control or power-monitoring firmware.
