Push-button switch to turn on/off the 73S8009CN.
Note: OFF_ACK must be set high to turn off.
When set to 1-2, the ON_OFF input is set to ground
which turns on the 73S8009CN when power is
applied. When set to 2-3, the push button switch is
connected to the ON_OFF pin.
The VPC input can select between the VPC_IN and
the 3.3 V inputs. When selecting the VPC_IN, the
VDD output can source the 3.3 V supply on the
evaluation board. See the description for JP4.
USB DP
USB DM
Two-pin test points for each respective smart card
signal. The pin label name is the respective signal
(i.e. VCC, CLK) and the other pin is GND.
USB Connector for USB enabled smart cards.
Connector that either gathers or supplies the 3.3 V
supply. It includes the 73S8009CN host control signal
pins RDY, CS, OFF_REQ, OFF_ACK, CMDVCC%,
CMDVCC#, SCIOEN and RSTIN.
SIM/SAM smart card format connector.
Note that J6 is wired in parallel to the smart card
connector J5 (underneath the PCB). J5 and J6 are
never to be used at the same time.
When the jumper is inserted, the 73S8009CN VDD
output is connected to the 3.3 V power plane. When
using in conjunction with a
or other host, it supplies the 3.3 V source on the
platform if it is so configured. Caution must be taken
as damage could occur if the
Board or host is sourcing 3.3 V with this jumper
inserted. Removal of the jumper provides proper
isolation with any host platform.
When inserting a card (credit card size format),
contacts must face up.
CS Disable Jumper. Insertion of jumper disables the
73S8009CN. The state of the CMDVCC#, CMDVCC%
and RSTIN inputs are latched and the I/OUC,
AUX1UC and AUX2UC are tri-stated. The OFF and
RDY outputs are also tri-stated.
