integrated LCD controller
LH754xx and LH7952x

ARM7-based MCUs with integrated
LCD controller

These flexible, powerful microcontrollers, based on ARM7 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 design a wide range of applications.

Applications

4 Any application that uses an LCD display
– Consumer
– Entertainment
– Industrial/commercial
– Medical
– Automotive

These ARM7-based microcontrollers integrate an LCD
controller, for powerful, flexible performance in all sorts of
applications, including consumer, entertainment, industrial/
commercial, medical, and automotive.

The LH754xx family uses a 84-MHz, 32-bit ARM7TDMI-S as its
core, while the the LH7952x uses a 77-MHz, 32-bit ARM720T.
They all use a 1.8-V core supply, with a 3.3-V I/O supply, and
operate within -40 to +85 °C.

High integration and a range of options make it easy to select
the right set of features, whether the end product is a low-cost
consumer device or a media-rich system.
