The
LH7A404 is a true System-on-Chip designed from the ground up to provide high processing
performance, low power consumption, and a high level of integration.
 The
emergence of highly integrated ARM9 System-on-Chips opens the door for a wide
range of multimedia applications in mobile information appliances. These appliances
require high processing performance and low power consumption.
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, 3.3 V I/O) and on-chip
PLL.
