VPC select
Jumper to select between a clock from 12xx device or
external clock as the frequency reference to the device.
The setting of these two jumpers depends on the type
of smart card connector used (whether switch is
nominally open or closed), and which of the card
presence switch input of the 73S8009R is used. In this
demo board, the switch is nominally open. The
jumpers can be set in one of two ways:
BNC input for external clock when JP1 is in the
EXTCLK selection (jumper JP1 between terminal 2 and
3).
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.
Two-pin header. Shorting bar jumper must be in place
for normal operation. The shorting jumper can be
replaced with an ammeter to measure the VDD current
to the IC. VDD must be at set with a 3.3V supply.
Connector that gathers the 3.3V supply of the board,
the 73S8009R host control signal pins RDY, CS,
RESET, TEST, PWRDN, CMDVCC%, CMDVCC#, and
RSTIN.
SIM/SAM smart card format connector
Note that J6 is wired in parallel to the smart card
connector J5 (underneath the PCB). No SIM/SAM
should be inserted when using the credit-card size
connector J5.
Two-pin header. When shorted with a jumper, the
device is in power down mode.
When inserting a card (credit card size format),
contacts must face up.
Two-pin header. Shorting bar jumper must be in place
for normal operation. The shorting jumper can be
replaced with an ammeter to measure the VPC current
to the IC. VPC must be at set with a 5V supply.
Connector that gathers the 5V supply of the board, the
73S8009R interface IOU, external clock (SCLK) and
interrupt (OFF) pins.
Smart card connector.
1. Default setting: Use of PRES: JP5 must be set to
2. Alternative use: Use of PRES: JP5 must be set to
PRES, and JP6 set to VDD.
PREB, and JP6 set to GND.
