Data Sheet
Introduction:
It is a fast, inexpensive production solution for
adding a graphic user interface to an embedded
product. GEMexpress
TM
allows for greater design
flexibility and a shorter time to market. This new
hardware approach to GUI integration contains all
of Amulet’s bill of materials, which is everything
needed to drive the user interface. It just needs
to be attached to a simple display interface board
and the human interface is ready for production.
As it’s easy to integrate, Amulet sees it as the
“express” lane to production: fast, easy and cost
effective.
Features:
•
Amulet AGB75LC04-BG-E 225-ball
LFBGA Graphical OS Chip™
•
Integrated resistive 4 or 5 wire touch panel
decoder
•
Storage Capacity – 32megabit SerialFlash
for storing GUI pages
•
64megabit SDRAM (frame buffer)
•
Serial Interfaces – 3.3v UART, TWI, USB
•
Two 50 Pin Interface Connectors for LCD
signals, power and serial communication
•
Dedicated Crystal for System
•
Small and compact 1.5” x 3.0”, fits within
the outline of a 3.5” TFT.
