Key Features
- 16-bit dsPIC33EP GS core delivering 70 MIPS at 60 MHz with hardware barrel shifter for fast control-loop execution in switch-mode power supplies
- 16 KB of on-chip Flash and multiple internal bus architecture enabling single-chip digital power control without external memory
- 28-pin QFN-S-28 package with boundary-scan JTAG support for fast prototyping and in-circuit debug in power electronics designs
Applications
DSPIC33EP16GS502-I/MM is optimized for digital power conversion applications including LLC resonant converters, totem-pole PFC stages, and DC-DC buck/boost controllers where 70 MIPS real-time loop performance at 60 MHz is required. Its hardware barrel shifter and dedicated multiply-accumulate unit accelerate PID and peak-current-mode control algorithms without software overhead. The compact 28-pin QFN is also well suited for solar micro-inverters and motor drive auxiliary power supplies where board space is tightly constrained.

Frequently Asked Questions
How does the 70 MIPS throughput of DSPIC33EP16GS502-I/MM help close digital power-conversion control loops?
At 70 MIPS the DSPIC33EP16GS502-I/MM can execute a complete voltage or current control loop — including ADC read, PID calculation, and PWM update — in under 1 µs. This is fast enough to regulate switching frequencies above 200 kHz in LLC resonant converters and totem-pole PFC stages without requiring an external FPGA or DSP.
What is the significance of the hardware barrel shifter in DSPIC33EP16GS502-I/MM for power control firmware?
The barrel shifter performs multi-bit shifts in a single clock cycle instead of multiple sequential cycles, which is critical for fixed-point scaling operations in PID compensators. In a 16-bit control loop running at 60 MHz, saving 4 to 8 cycles per shift operation can free enough headroom to run two independent control loops, such as voltage and current regulation, on the same device.
What flash memory does DSPIC33EP16GS502-I/MM offer, and is it sufficient for a complete digital power controller firmware image?
DSPIC33EP16GS502-I/MM provides 16 KB of on-chip program Flash. For a typical LLC converter or PFC controller firmware — consisting of a startup state machine, PID compensator, fault handler, and UART diagnostic shell — 16 KB is sufficient when compiled with optimizations, eliminating the need for external serial Flash and reducing BOM cost.
