Prototypes & Products


You will find hereafter the FingerChip devices, prototypes or products, designed and developped by the FingerChip team within Thomson-CSF, then Atmel. Well, my memory is not so good, so some mistakes may occured, sorry about that.

This photo illustrates the gap between the first FingerChip swipe sensor, and the latest generation: the first was a slow chip, with a large pixel area to make sure to acquire enough fingerprint data for recognition.

same as the AT77C102, excepted the width: only 128 pixels.

AT77C104

2003

8x232

SPI interface, navigation and click detection

AT77C105

2005

8x232

clone version of the C104 with extended I/O voltage range (1.8v-3.3V)

AT77C108

2007

6x192

low power consumption, low cost, navigation and click, wake-up, molded package

AT77C109

2008

6x192

integrated USB interface, navigation and click, wake-up, encryption, fake finger detection, molded package...


And what about the C106 and C107? Ah! Around 2005, we started the design of chips that integrates a reconstruction algorithm, to save throughput rate and memory for applications. The chips reached the emulation stage, but it was decided not to go further.
