Specifications
3.5 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 from 0 MHz to 96 MHz (core operating frequency 150 MHz) with an operating supply voltage
from V_{DD min} to V_{DD max} under an operating temperature from T_L to T_H. All timing is measured at 30 pF loading.
