Description
USB D- connection to / from USB controller.
When SC/ USB is set low, this pin is electrically
connected to the AUX1 pin, otherwise it is isolated.
CMDVCC%
CMDVCC#

I
I
Logic low on one or both of these pins will cause the
LDO regulator to ramp the Vcc supply to the smart
card and smart card interface to the value described
in the following table:
CMDVCC%
CMDVCC#
Vcc Output Voltage
0 0 1.8V
0 1 5.0V
1 0
3.0V
1 1 Vcc Off
Supervision for more details.
RSTIN

I
Reset Input: This signal is the reset command to the
card.
RDY
8
O
Signal to controller indicating the 73S8009CN is
ready because V CC is above the required value after
CMDVCC% and/or CMDVCC# is asserted low. A
20kΩ pull -up resistor to V DD is provided internally.
Pull-up is disabled in Power down state and CS=0
modes.
ON/OFF
24
I
Power control pin. Connected to normally open
SPST switch to ground. Closing switch for duration
greater than de-bounce period will turn 73S8009CN
circuit “on”. If the 73S8009CN is “on,” closing the
switch will turn 73S8009CN to “off” state after the
de-bounce period and OFF_REQ/OFF_ACK
handshake. Can be controlled by a host processor
digital output.
OFF_REQ
11
O
Digital output. Request to the host system controller
to turn the 73S8009CN off. If ON_OFF switch is
closed (to ground) for de-bounce duration and circuit
is “on,” OFF_REQ will go high (request to turn OFF).
Connected to OFF_ACK via 100k ? internal resistor.
OFF_ACK
13
I
Setting OFF_ACK high will power “off” all analog
functions and disconnect the 73S8009CN from V PC .
The pin has an internal 100kΩ resistor connection to
OFF_REQ so that when not connected or no host
interaction is required, the Acknowledge will be true
and the circuit will turn “off” after the deactivation
sequence is completed.
