Description
VV6500-C048
VGA resolution CMOS sensor,
48LCC package
STV0672-001
CPiA2 coprocessor
STV-USB/VGA-E01
USB chipset
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
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.
