W6668F

The W6668F is a high integrated USB scanner control processor. It provides the system required signals for all necessary of a CCD/CIS scanner, the signal interface includes CCD/CIS sensor, image buffer memory, motor drive, lamp/LED drive and other mechanacal input/output signals.

Features of W6668F are: (1)complete scanner on one chip solution for sheetfeed and flatbed scanners; (2)internal timing generator for 300,600 or 1200 dpi CCD/CIS sensor; (3)builin control signals for CCD lamp, CCD electric shutter, or CIS LED drive; (4)multiple CCD transfer gate driver supported to extend CCD exposure time; (5)exposure time of multiple CCD transfer gate driver can be programmed individually; (6)16-bit A/D converter.

What comes next is about W6668F  maximum ratings: (1)supply voltage with respect to VAVSS: -0.3 V to 6 V; (2)voltage on any pin other than supplies: -0.3 to VDD+0.3 V; (3)current at any pin other than supplies: 0 mA to 10 mA; (4)storage temperature: -65 to 150 .
