BU1594AGS/AGLU
Description
Dimension (Unit : mm)
BU1594AGS/AGLU series are camera/LCD interface
LSIs designed for folding type cellular phones.
This LSI enables to control camera/LCD signal and to
reduce the number of main internal wires in the hinge
part of the cellular phones, thus it is advantageous for
radiation noise countermeasures. Hardware control
of camera image inputting, LCD display and JPEG
encode/decode makes it possible to greatly reduce
the load on the CPU.
