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.
|Infrared camera||1995||128x128||first images with the uncooled infrared camera, converted into a fingerprint sensor|
|FC8x8||1996||160x160||first square fingerprint thermal sensor|
|FC2x17||1997||40x350||first swipe sensor in the world|
|FC15A140||1998||30x280||industrial version of the sweep fingerprint sensor|
|FCD4B14 AT77C101||1999||8x280||integrated analog to digital converter, 5 volts|
|AT77C102||2001||8x280||clone version of the C101 in a new CMOS process, 3.3 volts|
|AT77C103||2002||8x248||First fingeprint sensor with integrated USB interface|
|Mini-clone||2003||8x128||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.
