Introduction

The TC5747 is a single chip VGA (640 lines over 480 pixels) color CMOS sensor with an integrated color

processing and JPEG codec. It is designed to meet the requirements of cellular devices with low power

consumption and miniature size. An embedded programmable core with dedicated hardware performs the

extensive color processing. An embedded real-time JPEG encoder and compressed frames SRAM store

JPEG images on chip. The TC5747 has flexible interfaces and supports multiple video output formats for

easy integration into cellular phones. It supports a 16-bit host interface for fast data access and control.
