Key Features
- 70 MIPS 16-bit dsPIC33EP GS core with barrel shifter delivers high-speed PID and compensation-loop calculations for digital power conversion at switching frequencies above 100 kHz
- Integrated ADC, DAC channels, and CAN interface on a single 44-pin TQFP device eliminates multiple external data-conversion chips in compact digital power supply designs
- 64 KB flash and 8 KB RAM with JTAG boundary scan provide sufficient code space for complex control algorithms plus field-upgradeable firmware via CAN bootloader
Applications
The DSPIC33EP64GS804-I/PT is optimized for digital power supply controllers, DC-DC converter management, and active power-factor correction circuits where the 70 MIPS core handles real-time compensation loops at switching frequencies from 100 kHz to 500 kHz. Its on-chip ADC and DAC channels eliminate external conversion ICs in isolated gate-driver feedback loops and current-sensing circuits for solar inverters and UPS systems. The CAN peripheral enables network-managed power shelf architectures common in telecom rectifiers and industrial distributed power systems.

Frequently Asked Questions
How does the DSPIC33EP64GS804-I/PT 70 MIPS performance support a 400 kHz digital power-supply control loop?
At 70 MIPS, the dsPIC33EP64GS804 executes approximately 175 instruction cycles per 400 kHz switching period (2.5 µs), allowing a full 3-pole 3-zero digital compensator with ADC sampling, output calculation, and PWM duty-cycle update to complete in under 1 µs. This leaves 60% of the CPU bandwidth free for supervisory tasks like fault handling, CAN communication, and thermal derating algorithms, enabling a fully integrated digital controller without an external DSP co-processor.
What advantage does the integrated CAN peripheral on the DSPIC33EP64GS804-I/PT provide in a power-shelf management system?
The on-chip CAN interface allows the DSPIC33EP64GS804-I/PT to participate in a PMBUS or CANopen power-management network without an external CAN transceiver IC beyond the physical-layer driver, reducing the BOM by at least 1 component. In a rack-mounted power shelf with 8 to 16 converter modules, the CAN bus enables centralized fault reporting, load sharing, and firmware updates over the bus at 1 Mbps without pulling individual boards for JTAG programming.
For a solar microinverter design, how do the DSPIC33EP64GS804-I/PT ADC and DAC channels simplify the signal chain?
The integrated ADC on the DSPIC33EP64GS804-I/PT samples input voltage, output voltage, and inductor current signals simultaneously using multiple S&H channels at up to 3.5 Msps, feeding the 70 MIPS compensation loop with fresh measurement data every 286 ns. The companion DAC channels generate analog reference signals for gate-drive comparators or analog current limiters, replacing 2 to 3 external op-amp stages. Together, these on-chip peripherals reduce the analog signal-chain component count by 30% to 40% in a single-phase 250 W solar microinverter.
