s Interfaces (continued)
6. SDRAM interface
This product’s SDRAM interface supports JEDEC standard single data rate SDRAM with a CAS latency of 3, a cycle
time of 8 ns or faster, and an access time of 6 ns or faster.
Data is transferred in 32-bit units, and either one 64M 32-bit data path SDRAM chip or two 64M 16-bit data path
SDRAM chips may be used.
