Prototypes & Products: AT77C109

In 2008, the AT77C109 was a USB version of the AT77C108: 6x192 pixels 500 dpi, navigation and extremely low power wake-up function integrated plus some specific security functions: fake finger detection, data encryption (memory bridge) and challenge response.

This chip was debug with a ceramic package (and was OK at the first run), and the production was using an extremely small footprint molded package.
