SERIAL INTERFACE / ISO DRIVER
Integrated in the CY100 is one bi-directional serial interface
driver, enabling data transfer according to ISO 9141. The
driver can be used, for example, as the diagnosis interface,
for an immobilizer or for a generator interface. If the interface
is not used, the transmitter side can be deployed as a small-
signal stage.
The input/output pin RT is protected against destruction
from ISO impulses 3a and 3b.

SMALL SIGNAL STAGES
Two identical small-signal stages with open-drain outputs
are integrated in the CY100. The output stages are mainly
for digital outputs, for the control of “semi-intelligent” actors
( e.g. semi-conductor relays ) and for driving LEDs.
The inputs E1 and E2 are realized as comparators with
VDDIO - dependent threshold. The inputs have pull-up
current sources, so that in case of an open input, the output
stages are disabled. The phase of the outputs is non-
inverting.
The output stages are disabled ( transistors switched off ),
when the reset signal on RST is active.

The transmit-function has to be enabled via SPI soft reset
after an active RST ( low ). The open-drain outputs are
current-limited, in addition the output voltage on Ax
( x=1;2 ) is monitored for plausibility. If the voltage at Ax
still exceeds a certain defined threshold after switch on the
output transistor and after a predefined time tvoff, a short-
circuit to battery is detected and the stage is turned off.
The output stages can also be diagnosed. The error
conditions short-circuit to battery ( SCB), short-circuit to
ground ( SCG ) and open-load ( OL ) are detected. Error
detection is done selectively according to the output stage
condition : OL and SCG are detected when the output
stage is disabled; SCB is detected when the output stage is
on. The errors OL , SCB and SCG are filtered.

The OL diagnosis can be disabled individually via the SPI
interface for each output stage for applications, for which the
diagnostic current can disturb ( e.g. LEDs ). Disable
means, zero diagnostic current for OL and deactivated
error indication OL.
