Timings are given assuming a capacitance load on data, control and address pads:
Table 44-30. Capacitance Load on Data, Control and Address Pads
Table 44-31. Capacitance Load on SDCK Pad
The SDRAM Controller satisfies the timings of standard PC100, PC133 (3.3V supply) and
Mobile SDRAM (1.8V supply) which are given in
