YINGHUA DSPIC33EP128GS804-EPTVAO TQFP44 semiconductor

Microcontroller for embedded control

The YINGHUA DSPIC33EP128GS804-EPTVAO is a dsPIC33EP series microcontroller packaged in a 44-pin TQFP. It provides 128 KB of program memory for deterministic signal processing and control algorithms. Engineers designing motor drives, power conversion or sensor interfaces use this device for its integrated peripherals and real-time performance.

Low-power operation in typical use

The chip draws modest current while executing control loops at 33 MIPS, keeping junction temperature low in normal ambient conditions. Static consumption remains minimal during idle or sleep modes, allowing battery-powered or fanless designs. No active cooling is required for standard workloads.

Sustained throughput under continuous load

The core maintains 33 MIPS throughput during extended interrupt-heavy routines without thermal throttling. Peripheral modules such as ADCs and PWM generators operate concurrently at full rate. Firmware must manage peripheral clock gating to optimise long-term power budget.
