Preliminary
Description
Atmel's AT71201M is a full-frame sensor based on charge-coupled device (CCD)
technology. It can be used in a wide range of applications thanks to operating mode
flexibility, very high definition and high dynamic range.
The nominal photosensitive area is made up of 4096 x 4096 useful pixels and is split
into four independent zones that are driven separately by four independent four-phase
clock sets. Thus the sensor can be used in up to 12 main modes.
The large format and high definition make the device suitable for any application
requiring precision.
The high sensitivity of the 11 x 11 µm pixels with 100% fill factor provides a large
bandwidth of response with up to 1100 nm wavelength.
Two serial registers and four independent output amplifiers offer a high-frequency
functionality at 40 MSPS and up to 7.4 frames per second with a high signal to noise
ratio.

Notes: 1. The full-frame version can be read through one, two or four outputs
2. The lines summation into the register is made by a specific timing diagram. The inte-
gration time should be adapted to prevent charge overflow.
A specific clock allows column summation.
The pixel size is 11 x 11µm2 with 100% fill factor (photo-MOS technology).
The sensor is compatible with a 180° rotation.
The image zone commands are split in 4 horizontal areas. The combination of the
ΦPij clocks allows various transfer configurations.
The serial registers are driven by 8 ΦLi clocks. An adapted combination of them allows
transfers of 100% of stages to the right side or the left side or 50% in each direction.
