AS-Interface Slave IC
AS2701A (ISA3+)
Rev. C, October 2000
Page 11 of 16
For successful programming the programmer hardware must have sink/source capability of at
least 5 mA, and the AS-Interface Slave IC's supply voltage LTGP has to be in the range of
26.65 V ...33.35 V.
The only E
2
PROM address locations which can be programmed through the AS-Interface
Slave IC (hence over the AS-Interface Bus and by the AS-Interface Master), are locations 0
and 1, which both have been reserved for the AS-Interface Slave unit's address.
The E

PROM has to be programmed in the following way:

The interface is intended for the supply voltage to actuators, sensors as well as external
circuits with a power supply of <35mA without overloading the AS-Interface line in the range of
the signal frequency. The AS-Interface slave IC has an internal circuit protector which limits the
current during the charging of the load capacitor and which effects a power down at thermal
overload, e.g. at too high output currents.
In the case of a current break down on the AS-Interface line of less than 1ms, the internally
stored information is retained. The supply voltage of the IC during this time is extracted from
the capacitor Pin UOUT which is disconnected from the AS-Interface line.
