Operating Conditions
The following operating conditions must not be exceeded in order to ensure correct
operation of the C164CI. All parameters specified in the following sections refer to these
operating conditions, unless otherwise noticed.

Overload conditions occur if the standard operatings conditions are exceeded, i.e. the voltage on any pin
exceeds the specified range (i.e.
V

- 0.5 V). The absolute sum of input overload
currents on all pins may not exceed 50 mA. The supply voltage must remain within the specified limits.
Proper operation is not guaranteed if overload conditions occur on functional pins line XTAL1, RD
, WR, etc.

4)
The timing is valid for pin drivers operating in default current mode (selected after reset). Reducing the output
current may lead to increased delays or reduced driving capability (

).
5)
The current ROM-version of the C164CI is equipped with port drivers, which provide reduced driving capability
and reduced control. Please refer to the actual errata sheet for details.
