MT9V022I77ATM (mono)
MT9V022I77ATC (color)
1/3-Inch, Wide-VGA CMOS Digital Image Sensor
Rugged Specs and High Quality for Scene-Understanding
and Smart Imaging Applications Micron’s MT9V022 has specifi-
cally been designed to support the demanding interior and exterior
needs of automotive imaging, which makes it ideal for a wide vari-
ety of scene understanding and smart imaging applications in real-
world environments. This wide-VGA CMOS image sensor features
DigitalClarity™, Micron’s breakthrough, low-noise CMOS imaging
technology that achieves CCD image quality (based on signal-to-
noise ratio and low-light sensitivity) while maintaining the inher-
ent size, cost, and integration advantages of CMOS.

Output Data Timing
Output Data Timing
The data output of the MT9V022 is synchronized with the PIXCLK output. When
LINE_VALID is HIGH, one 10-bit pixel datum is output every PIXCLK period.

Serial Bus Description
The MT9V022 control registers are written to and read from the two-wire serial interface
bus. The MT9V022 is a serial interface slave with four possible IDs (0x90, 0x98, 0xB0, and
0xB8) determined by S_CTRL_ADR0 and S_CTRL_ADR1 inputs.
Data is transferred into the MT9V022 and out through the serial data (SDATA) line. The
SDATA line is pulled up to VDD off-chip by a 1. 5kΩ resistor. Either the slave or master
device can pull the SDATA line down. The serial interface protocol determines which
device is allowed to pull the SDATA line down at any given time.
Register Lock
A register lock feature is included in the MT9V022 to help reduce the probability of an
inadvertent, noise-triggered two-wire serial interface WRITE to the sensor. The user may

image orientation, and an unintended flip to the image can cause serious results.
