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, I2C, I2S, 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 -40°C to +85°C and is offered in a 176-pin LQFP package.

SHARP’s LH79525 design provides low power, exceptional perfor-mance, good ? exibility, and great value in a 32-bit processor with a

16-bit external data bus.
