S1
ON/OFF switch
Push-button switch to turn on/off the 73S8009C.
Note: OFF_ACK must be set high to turn off.

JP3
ON_OFF Jumper
When set to 1-2, the ON_OFF input is set to ground
which turns on the 73S8009C when power is
applied. When set to 2-3, the push button switch is
connected to the ON_OFF pin.
When using VBUS as an always on configuration,
JP3 must be set to the 1-2 position and the
OFF_ACK input must be grounded.

JP2
VPC Select
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.

J4
Board 3.3 V
supply and digital
control signals
Connector that either gathers or supplies the 3.3 V
supply. It includes the 73S8009C host control
signal pins RDY, CS, OFF_REQ, OFF_ACK,
CMDVCC%
,
CMDVCC#
, and RSTIN.

J6
Smart Card
Connector
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.

JP4
VDD Select
When the jumper is inserted, the 73S8009C VDD
output is connected to the 3.3 V power plane.
When using in conjunction with a
73S
12xxF
Evaluation Board or other host, it supplies the 3.3 V
source on the on that platform if it is so configured.
Caution must be taken as damage could occur if the
73S
12xxF Evaluation Board or host is sourcing
3.3 V with this jumper inserted. Removal of the
jumper provides proper isolation with any host
platform.
