DESCRIPTION
The LH79525 is a low cost microcontroller that utilizes the ARM720T
core integrated with a wide variety of functions including the capability
to control STN, color STN, TFT, HR-TFT, and AD-TFT displays with up to
4,096 colors. Other functions include: 16KB of on-chip SRAM, 10/100
BaseT Ethernet MAC, USB 2.0 Full Speed Device, three UARTs, SSP, I

S, three 16-bit Counter/Timers, Analog to Digital Converter with inte-
grated touch screen controller, SDRAM Controller, Watchdog Timer, and
Low Voltage Detector. The LH79525 operates up to 77.4 MHz at 3.3 V over
the industrial temperature range of -40C to +85C and is offered in a
176-pin LQFP package.
SHARP's LH79525 design provides low power, exceptional perfor-
mance, good fl exibility, and great value in a 32-bit processor with a
16-bit external data bus.
