Hi, I want to know the following details about Atom E680T:


1. Architecture: Is it Tunnel Creek? From where can I get a lucid explanation of the architecture?


2. L2 cache: Is it ECC supported? Can the L2 Cache be configuarable as SRAM and stashing memory?


3. L1 cache: How much is the L1 data and instruction cache?


4. DDR2 memory Type: Is this 32bit or 64bit supported?


5. Storage interface: Is this SD/MMC supported?


6. Other interfaces: Is this SPI, I2C, DUART, CAN supported?
