The AC characteristics consist of output delays, input setup and hold times, and signal skew times. All
signals are specified relative to an appropriate edge of other signals. All timing specifications are specified
at a system operating frequency (HCLK) from 0 MHz to 133 MHz (core operating frequency 266 MHz)
with an operating supply voltage from V
All timing is measured at 30 pF loading with the exception of fast I/O signals as discussed below. Refer
to the reference manual’s System Control Chapter for details on drive strength settings.

known as Fast I/O) to achieve 133 MHz operation. These critical signals include the SDRAM Clock
(SDCLK), Data Bus signals (D[31:0]), lower order address signals such as A0-A10, MA10, MA11, and
other signals required to meet 133 MHz timing.
The values shown in
taken to minimize parasitic capacitance of associated printed circuit board traces.
