MT9P031: 1/2.5-Inch 5-Mp Digital Image Sensor
MT9P031 Image Sensor
Product Brief
Micron’s MT9P031 is a 1/2.5-inch CMOS digital image sensor
with an active-pixel array of 2592H x 1944V.
It incorporates
sophisticated camera functions such as windowing, binning,
column and row skip mode, and snapshot mode. It is program-
mable through a simple two-wire serial interface. The MT9P031
produces extraordinarily clear, sharp digital pictures, and its ability
to capture both continuous video and single frames makes it the
perfect choice for a wide range of consumer and commercial secu-
rity applications, including high resolution network cameras; pan,
tilt, and zoom cameras; and hybrid video/still cameras.

General Description
The MT9P031 sensor can be operated in its default mode or programmed for frame size,
exposure, gain setting, and other parameters. The default mode outputs a full-resolution
image at 14 frames per second (fps).
An on-chip analog-to-digital converter (ADC) provides 12 bits per pixel. FRAME_VALID
and LINE_VALID signals are output on dedicated pins, as is a pixel clock that is synchro-
nous with valid data.
The 5-megapixel CMOS i`mage 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 inherent size, cost, and
integration advantages of CMOS.

MT9P031: 1/2.5-Inch 5-Mp Digital Image Sensor
Functional Overview
Functional Overview
The MT9P031 is a progressive-scan sensor that generates a stream of pixel data at a con-
stant frame rate. It uses an on-chip, phase-locked loop (PLL) to generate all internal
clocks from a single master input clock running between 6 MHz and 27 MHz. The maxi-
mum pixel rate is 96 megapixels per second, corresponding to a clock rate of 96 MHz.
Figure 3 illustrates a block diagram of the sensor.

The sensor is programmed via the two-wire serial bus, which communicates with the
array control, analog signal chain, and digital signal chain. The core of the sensor is a 5-
megapixel active-pixel array. The timing and control circuitry sequences through the
rows of the array, resetting and then reading each row in turn. In the time interval
between resetting a row and reading that row, the pixels in the row integrate incident
light. The exposure is controlled by varying the time interval between reset and readout.
Once a row has been read, the data from the columns are sequenced through an analog
signal chain (providing offset correction and gain) and then through an ADC. The out-
put from the ADC is a 12-bit value for each pixel in the array. The ADC output passes
through a digital processing signal chain (which provides further data path corrections
and applies digital gain). The pixel data are output at a rate of up to 96 Mp/s, in addition
to frame and line synchronization signals.
