Application & Notes
ADUC845BS8-3 by Rochester Electronics, LLC is a 8052 microcontroller widely used in industrial control, motor drives, IoT devices, 3D printer mainboards, and consumer electronics. The 52-QFP package fits automated SMT assembly. Operating temperature is -40°C ~ 125°C — verify your application environment. The C8 variant has 64KB Flash / 20KB RAM; for larger firmware use the CB (128KB) or RC (256KB) variants. Pin-compatible domestic alternatives include GigaDevice GD32 series and Artery AT32 series — note GD32 ADC specs may differ slightly from ST originals.
