SMC Interface
The Static Memory Controller (SMC) interface of the ADSP-BF609
EZ-KIT Lite contains a 32 MB (16M x 16) Numonyx PC28F128P33B
parallel flash chip. Flash memory is connected to the 16-bit data bus and

Ethernet Interface
The ADSP-BF609 processor has two Reduced Media Independent Inter-
faces (RMIIs), one of which connects to an external Ethernet PHY device.
The EZ-KIT Lite provides a National DP83848C, Auto-MDIX, fully
compliant PHY with IEEE 802.2/802.2u standards. The PHY supports
10BASE-T and 100BASE-TX operations.
