MX88L60UC

GENERAL DESCRIPTION

The MX88L60 is a general-purpose controller for dualmode (tethered and portable) PC cameras and toy cameras. The MX88L60 contains all the necessary hardware supports, like image sensor control and interface, image capture and processing, proprietary video compression, memory control, USB and UART interface, embedded micro-controller and general-purpose I/Os. With the intensive hardware and associated software supports, it is an ideal solution for a tethered digital video camera, which can capture real-time live video for entertainment or videoconference applications. For still image capture, the MX88L60 can also function as a controller for low-cost digital still camera (DSC) or toy camera. With Flash memory interface support and power- saving control, it can make the system work on battery power for portable purpose.
