EVM board hardware can be divided into seven functional areas—see Figure
3–1 for a block diagram and Figure 3–2 for specific location information:
1394 Interface: The EVM connects to a PC/Macintosh via a 1394 port. Two
1394 ports are supplied. These are controlled by a 2 Port PHY
(TSB41AB2).
StorageLynx (TSB42AA9): The StorageLynx functions as a bridge (com-
mand translation) between the ATA/ATAPI drive and the PC/Macintosh.
ATA/ATAPI 40 Pin Connector: Adapters may be used for 44 pin
connections.
Flash Memory: 128K x 8 bit, access times may vary
Note:
Flash memory will only work correctly in 50–MHz mode with 60–ns, or faster,
access–time parts.
Serial EEPROM: 4K
8051 ICE Interface. The EVM contains a socket for connection to an
external 8051 emulator board. The 8051 ICE is used to access TSB42AA9
