1.1 Hardware Features
• Integrated ARM720T 32 bit RISC processor, capable of running at 72MHz.
• High performance 32-bits bus (AHB)
• Centralized address decoding for all AHB devices
• Four possible memory maps:
– external boot
– internal flash boot
– internal ROM boot
– normal operation
• Supports USB 1.1 compliant interface for down loading data from PC
• Support for flash-card applications:
– Supports the Multi Media Card (MMC)
– Supports Smart Media Card (EBI)
– NAND FLASH (EBI)
• Memory interface (EBI) supporting a number of memory types like Static RAM, SDRAM, external Flash.
The maximum bus frequency can be up to 48MHz.
• Integrated CD block decoder for CD-DA and MP3 CD applications
