DESCRIPTION
The LH7A400, powered by an ARM922T, is a com-
plete System-on-Chip with a high level of integration to
satisfy a wide range of requirements and expectations.
This high degree of integration lowers overall sys-
tem costs, reduces development cycle time and accel-
erates product introduction.
