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.
