The ZC0302 chip provides a cost effective single chip solution for the PC camera application. It communicates with
PC host via Universal Serial Bus (USB) port. All major image processing functions, such as image signal
processing (ISP), image data compression and data transfer units are built in the chip. Meanwhile ZC0302 also
provides high quality audio sampling function for sound recording. The audio function complies with USB audio class
1.0.
ZC0302 is designed as a cost-effective single-chip device replacing the complex and costly chip sets used in current
PC camera designs with embedded USB device controller and transceiver, 48-QFP package, and no external
DRAM requirement. Advanced on-chip image signal processor and JPEG encoder produce images with superior
quality.
1.1. General Features
Low cost, single chip solution for high resolution USB PC camera applications
Audio function complying to USB audio device class 1.0
Support up to 15 fps VGA video display without DRAM
USB Device Controller compliant with USB protocol 1.1
USB parameter configurable through EEPROM
Support 9/8-bit RGB Bayer pattern raw data input from CMOS image sensors
Support programmable color correction and gamma correction
Support programmable Auto Exposure/Auto White Balance
Support Auto Gain Control
Support ISO/IEC 10918-1 (JPEG) standard image compression
Support 4 quantization tables for programmable image quality
Support raw data output for high quality still image
3.3V I/O, 2.5V core
No external DRAM required
Flexible system level solution support
