DESCRIPTION
The advent of 3G technology opens the door for a
wide range of Multimedia and Java applications in
mobile information appliances. These appliances
require high processing performance and low power
consumption. The LH7A405 is designed from the
ground up to provide high processing performance, low
power consumption, and a high level of integration.
The LH7A405 combines a high performance 32-bit
ARM922T Core with a hardware-based JIT Java Com-
piler (Java Accelerator). The Java Accelerator provides
a platform to speed up and optimize Java applications
in silicon, keeping power consumption and memory
requirements at a minimum. Power consumption is fur-
ther 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.
