3.4 AC Electrical Characteristics
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 117 MHz (core operating frequency 333 or
350 MHz) with an operating supply voltage from VDD min to VDD max under an operating temperature
from TL to TH. All timing is measured at 30 pF loading with the exception of fast I/O signals which is
measured at 21 pF at a 6.5 mA drive strength setting. Refer to the reference manual’s System Control
Chapter for details on drive strength settings.
