GENERAL DESCRIPTION
VV5300 is a highly-integrated CMOS image sensing
device. In addition to a 160 x 120 pixel image sensor
array, the device includes on-chip circuitry to drive
and sense the array.
The output stage of the sensor contains a successive
approximation circuit which performs analogue-to-
digital conversion of the photodiode array to produce
8-bit or 4-bit pixel data.
VV5300 features electronic exposure and gain con-
trol over a wide range, enabling the use of a single
fixed-aperture lens.
A bi-directional 2-wire serial communications inter-
face allows the device to be configured and its oper-
ating status monitored. The status information may
also be multiplexed onto the digital output bus.
The primary image size is 160 x 120 but border pix-
els/lines can be enabled to give an effective image
size of 164 x 124.
