The Leader in CMOS Image Sensors
ICM320T
3.2 Megapixel QXGA Digital Color CMOS Image Sensor
Preliminary Data Sheet V1.0
General Description
The ICM320T is a high resolution, low power, small
form factor device 3.2Megapixel digital color CMOS
image sensor. The ICM320T is based on IC Media’s
high performance, wide acceptance angle 2.575µm
TopazPixel™ technology. The ICM320T supports a
1/2.7” optical format with short track lengths of less
than 7.0mm. High responsivity, low noise and image
quality enhancing filters results in excellent image
quality even in low light conditions.
The 2,048x1536 pixel array operates at up to 16fps at
full QXGA resolution, and at progressively higher
frame rates at 1/4 sub-sampled (1024x768) and 1/16
sub-sampled (512x384) resolutions. Low power
consumption and few required external discrete
devices makes the ICM320T ideal for small form
factor, battery-operated mobile consumer devices. It
consumes only 70mW at 15fps at QXGA and standby
current is 8µA.
The ICM320T image sensor’s registers are
programmed through an efficient, two-wire serial
control interface (SIF) enabling flexible control of the
sensor’s operating modes. It outputs 10-bit raw Bayer
(RGB) pixel samples synchronized to the associated
pixel clock (PCLK) as well as vertical and horizontal
synchronization signals (VSYNC/HSYNC).
