SUPPORT DOCUMENTATION EEPROM STV0672 STMicroelectronics have produced comprehensive Reference Design documentation for design-in of this Support EEPROM to initialise STV0672 (optional) USB data packets back to PC host chipset. The reference design includes schematics, gerbers, BOM and documentation to allow the implementation of a full production-ready camera. Contact STMicroelectronics for further details. ORDERING DETAILS Part Number This chipset allows the implementation of a high quality PC camera with a minimum of external components. The support EEPROM is optionally populated if a custom USB enumeration sequence is required. The STV0672 can perform inter-frame MPEG STV0672-001 STV-USB/VGA-E01 VV6500-C048 Description VGA resolution CMOS sensor, 48LCC package CPiA2 coprocessor USB chipset compression to a ratio of approximately 10:1. The companion ASIC can now also perform on the fly defect correction . No transceivers are required to interface to the USB bus, and no external components are required to meet the power management requirements of the USB specification. VV6500 has an ultra low power mode where the sensor will consume less than 50uA. Information furnished is believed to be accurate and reliable.
