MT9M114: 1/6-Inch 720p High-Definition (HD) System-On-A-Chip (SOC) Dig-
ital Image Sensor
Functional Description
ON Semiconductor’s MT9M114 is a 1/6-inch 1.26 Mp CMOS digital image sensor with an
integrated advanced camera system. This camera system features a microcontroller
(MCU), a sophisticated image flow processor (IFP), MIPI and parallel output ports (only
one output port can be used at a time). The microcontroller manages all functions of the
camera system and sets key operation parameters for the sensor core to optimize the
quality of raw image data entering the IFP. The IFP will be responsible for processing and
enhancing the image.
The entire system-on-a-chip (SOC) has superior low-light performance that is particu-
larly suitable for PC camera applications. The MT9M114 features ON Semiconductor’s
breakthrough low-noise CMOS imaging technology that achieves near-CCD image
quality (based on signal-to-noise ratio and low-light sensitivity) while maintaining the
inherent size, cost, and integration advantages of CMOS.
The ON Semiconductor MT9M114 can be operated in its default mode or programmed
for frame size, exposure, gain, and other parameters. The default mode output is a 720p
image size at 30 frames per second (fps), assuming a 24MHz input clock. It outputs 8-bit
data, using the parallel output port.
Architecture Overview
The MT9M114 combines a 1.26 Mp sensor core with an IFP to form a stand-alone solu-
tion for both image acquisition and processing. Both the sensor core and the IFP have
internal registers that can be controlled by the user. In normal operation, an integrated
microcontroller autonomously controls most aspects of operation. The processed image
data is transmitted to the host system either through the parallel or MIPI interface.
