MT9V135
1/4-Inch VGA CMOS Active-Pixel Composite
Analog and Digital Video Output Sensor
High-Performance Video Meets Low-Cost Home Security Systems
Built for home and commercial security systems,
Micron’s MT9V135 is a complete camera system-
on-a-chip (SOC) solution. Our unique low-noise,
stable-temperature design enables it to capture
extraordinarily clear images. Requiring less light
than a single candle produces, the MT9V135 creates
crisp images for networked security applications
that are just as effective on the darkest nights as
on the brightest days. The VGA CMOS image sensor
achieves CCD image quality (based on signal-to-noise
ratio and low-light sensitivity) while maintaining
the inherent size, cost, low power, and integration
advantages of CMOS
MT9V135 Applications
l Low-cost wireless, 900 MHz, 2.4 GHz cameras
l CCTV cameras
l Smart camera upgrades
l Vehicle and contents theft identification
l Small office monitoring
l Home monitoring
Professional Quality for Home Systems
Until the introduction of Micron’s MT9V135 device
for home security applications, designers were
forced to sacrifice performance for cost. Micron’s
¼-inch VGA SOC solution changes that. It offers
best-in-class performance while producing full-
color video, making scenes and stills clear enough
to enable e-mail or remote viewing. This versatile
imager meets the strong demand for low cost, excel-
lent color fidelity, and low-light sensitivity in video
sensors for home security.
Sophisticated but Simple
The MT9V135 incorporates sophisticated camera
functions on-chip and is programmable through
a simple two-wire serial interface. NTSC- and PAL-
formatted outputs are integrated on the device,
and its flexible signal path supports a wide variety
of system architectures. Because the sensor does not
require an encoder chip for formatting, this lowers
the bill of materials (BOM) and dramatically reduces
costs. In addition, by offering both analog and digital
output formats, the video sensor can be simultane-
ously viewed on a standard TV screen and captured in
digital video storage. The image data can be output
on any one of three output ports.
Dependable in Severe Conditions
Electronic components used in some security envi-
ronments need to perform under rigorous operating
conditions. Bright or dark, hot or cold, the MT9V135
can output full-color video at VGA-quality resolution
(640H x 480V). The extended temperature option
excels under extreme conditions, with an operating
temperature range of –40˚C to +105˚C.

MT9V135 Features and Benefits
Features Benefits
Pixel Size 5.6µm x 5.6µm Formatted for a 1/4-inch lens; among the most sensitive on the
market.
Video Formats
NTSC/PAL (true two-field) analog composite
video output
ITUR BT.656 parallel output (8 bit, interlaced)
The video output is formatted on the chip to go directly to an NTSC
or PAL input (display) device. Because the sensor does not require an
encoder chip, this lowers the bill of materials (BOM) and dramatically
reduces the cost.
Image Processing On-chip image flow processor (IFP) performs
sophisticated processing
The IFP consists of a color processing pipeline and a measurement
and control logic block (the camera controller). The measurement and
control logic continuously accumulate image brightness and color
statistics. Based on these measurements, the IFP calculates updated
values for exposure time and sensor analog gains that are sent to the
sensor core.
Automatic IFP
Features
Auto exposure, auto white balance (AWB), auto
black reference (ABR), auto flicker avoidance, auto
color saturation, and auto defect identification and
correction
The MT9V135 automatically detects and adapts to scene lighting
conditions.
MT9V135
Digital Video Input Supports use of external processing devices for
addition of custom overlay graphics
Lowers the BOM for post-processed video and requires less board space
(fewer chips).
Shutter Dual electronic rolling shutter (DERS)
The DERS provides excellent video capture, especially in low light
conditions, by featuring two rolling shutters (one for each video field)
that each can integrate for up to 33ms. This maintains an overall
frame rate of 30Hz for NTSC (25Hz for PAL). Competing rolling shut-
ter devices typically integrate for a maximum of 16ms or contain only
240 lines of information.
Active Array Format 640H x 480V, programmable to any smaller
frame size
Sized for optimal performance in standard VGA/NTSC displays. The
digital output mode is programmable to support smaller frame sizes to
suit the needs of numerous systems.
Frame Rate VGA 640H x 480V: 30 fps at 27 MHz (NTSC);
25 fps at 27 MHz (PAL)
The MT9V135 offers real-time frame rate at full resolution to match
frame rates of TV displays.
Scan Mode CCIR 656 interlaced Enables the MT9V135 to capture high-quality video, which it outputs in
standard color digital video format.
Data Formats
Progressive or interlaced, parallel or LVDS (serial).
The sensor supports parallel or serial digital
interlaced output formats (CCIR 656, YUV 4:2:2).
It also supports raw progressive or interlaced digital
output.
The MT9V135 offers a selectable output data format, providing the
flexibility for various system needs. Plus, its serial LVDS output mode
significantly reduces wire count.
