HB7121B
Semiconductor Inc.
System IC SBU
DESCRIPTION
HB7121B is a highly integrated single chip CMOS B/W image sensor using Hynix 0.5um CMOS process
developed for image application to realize high efficiency photo sensor. The sensor has 414X314 pixels total,
and 400X300 pixels effective. Each pixel is high photo sensitive, small size active pixel element that converts
photons to analog voltage signal. The sensor has three on-chip 8 bit Digital to Analog Convert (DAC) and 414
comparators to digitize the pixel output. The three on-chip 8 bit DAC can be used for independent gain
control. Hynix proprietary on-chip Correlated Double Sampling (CDS) circuit can reduce Fixed Pattern Noise
(FPN) dramatically. The whole 8 bit digital B/W raw data is directly available on the package pins and just a
few control signals are needed for whole chip control, so it is very ease to configure a system using the
sensor.
