DESCRIPTION

The LH79524/LH79525, powered by an ARM720T,

is a complete System-on-Chip with a high level of inte-

gration to satisfy a wide range of requirements and

applications. The SoC has a fully static design, power

management unit, and low voltage operation (1.8 V

Core, 3.3 V I/O). With the on-chip voltage regulator, a

single 3.3 V supply can be used as well. Robust periph-

erals and a low-power RISC core provide high perfor-

mance at a reasonable price.
