High image quality, ultraminiature size, and low power makes these devices optimal for use in cell phones

Frame Transfer Full-Color CCD Sensors

Frame Transfer CCD

Achieves the industry’s smallest optical size class by using the frame transfer CCD, which makes it possible to reduce feature sizes while maintaining sensitivity.

Sensitivity was increased by adopting a simple single-layer gate gap structure and thin-film polysilicon.

FT-CCD CMOS IL-CCD

SANYO fabricates frame transfer (FT) CCD sensors using unique technologies with ultrafine design rules and provides them as modules assembled using advanced leading-edge mounting technologies.

SANYO makes a point of providing fine and delicate semiconductor devices in forms that our customers will find approachable and easy to use.

CCD drive circuit and image processing implemented in a single package

Multifunction DSP chip

A charge pump type voltage step-up circuit that features minimal noise generation, and the supply voltages required for system drive are generated efficiently with just the supply of a single +2.9 V power supply. This design is also effective at achieving reduced power consumption.

SANYO implemented, in a single package, the timing generator circuit required for system drive and all the analog and digital processing required to accept the CCD output by taking advantage of the SANYO CMOS analog/digital hybrid process and MCP (multi-chip package) technologies.
