This is preliminary information on a new product now in development or undergoing evaluation. Details are subject to change without notice.
Release 1.3 - January 29, 2002
4.5.3. SDRAM INTERFACE
Figure 4-5
and
Table 4-8
list the AC characteris-
tics of the SDRAM interface. The MCLKx clocks
are the input clock of the SDRAM devices
The PC133 memory is recommended to reach
100MHz operation.
