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.

2) Overload conditions occur if the standard operatings conditions are exceeded, i.e. the voltage on any pin

exceeds the specified range (i.e.

VOV > VDD + 0.5 V or VOV < VSS - 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.

3) Not 100% tested, guaranteed by design and characterization.

Pin drivers in

default mode4)5)

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 (

CL).

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.
