LH7A Devices
These flexible, powerful microcontrollers, based on ARM9 cores, integrate
an LCD controller, so they save time-to-market for applications that use an
LCD screen. Supported by comprehensive software and hardware design
tools, they make it easy to create everything from cost-conscious consumer
systems to advanced systems with media-rich environments.
