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.

• DMA (12 Channels)

– External DMA Channels

– AAC (AC97)

– MMC

– USB

• USB Host and Device Interface (USB1.1)

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.

NOTE: *Under development. Results pending further

characterization.
