AT77C105A [Preliminary]
5419A–BIOM–01/05
Figure 13.
Example of an 8-bit Access
During an 8-bit access, the sensor transmits two pixels (each pixel is coded on 4 bits).
Figure 14.
Fast SPI Communication
Communication Speed
The acquisition speed of the pixels is linked to the clock’s communication speed. The
faster the communication clock, the faster the authorized maximum finger sweeping
speed. The sensor supports fast communications up to 16 Mbps.
Reading of Frame
A frame consists of 232 true columns and 1 dummy column of 8 pixels of 4 bits each. A
frame starts with a dummy column.
