DESCRIPTION
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.
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.
