Timings
Timing Diagram Conventions
This data sheet contains one or more timing diagrams. The following key explains the components used in these
diagrams. Any variations are clearly labelled when they occur. Therefore, no additional meaning should be attached
unless specifically stated.

Timing Conditions
Unless specified otherwise, the following conditions are true for all timing measurements.
T
A
= 0 to 70° C
CVDD = VDD_PLL = 1.8V
RVDD = 3.3 V
All grounds = 0 V
Logic 0 = 0 V, Logic 1 = 3.3 V
Output loading = 50 pF
Timing reference levels = 1.5 V
The Processor Bus Clock (HCLK) is programmable and is set by the user. The frequency is typically between
33 MHz and 100 MHz (92 MHz for industrial conditions).
