DESCRIPTION

– USB

The advent of 3G technology opens the door for a

wide range of Multimedia applications in mobile infor-

mation appliances. These appliances require high pro-

cessing performance and low power consumption. The

LH7A404 is designed from the ground up to provide

high processing performance, low power consumption,

and a high level of integration.

• USB Host and Device Interface (USB1.1)

The LH7A404 contains a high performance 32-bit

ARM922T Core. Power consumption is reduced by the

high level of integration, 80KB on-chip SRAM, fully static

design, power management unit, low voltage operation

(1.8 V Core, 1.8 V or 3.3 V I/O) and on-chip PLL.
