2. Applications
Flexibility and performance make this device suitable for digital photography, graphic
arts, medical or industrial applications and scientific analysis.
3. 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 comprises 4096 × 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 12 main modes.
The large format and high definition make the device suitable for any application
requiring precision.
The high sensitivity of the 11 × 11 µm
2
pixels with 100% fill factor provides a large
bandwidth response up to 1100 nm wavelength.
Two serial registers and four independent output amplifiers offer high-frequency func-
tionality of 4 × 40 Msps or 7.4 frames per second with high signal-to-noise ratio.
On customer request, frame transfer architecture:
– 2048 active lines, one memory zone with frame readout through one or
two outputs.
– 2048 active lines, two memory zones with frame readout through two or
four outputs.

1. The full-frame version can be read through one, two or four outputs.
2. Summation of lines into the register is made by a specific timing diagram. Integration time
should be adapted to prevent charge overflow.
A specific clock allows the column summation.
The pixel size is 11 × 11µm
2
with 100% fill factor (photo-MOS technology).
The sensor is compatible with a 180° rotation.
Image zone commands are split in four horizontal areas. Combination of
ΦPij
clocks allows vari-
ous transfer configurations.
Serial registers are driven by 8
ΦLi
clocks. An adapted combination of these allows transfer of
100% of stages to the right or left side or 50% in each direction.
