Page 5: Introduction
The Teridian Semiconductor Corporation 73S8009C Demo Board is a platform for evaluating the Teridian 73S8009C 32-pin QFN Smart Card Interface IC. It incorporates the 73S8009C integrated circuit, and it is designed to operate either as a standalone platform (to be used in conjunction with an external microcontroller) or as a daughter card to be used in conjunction with the 73S12xxF evaluation platform. -
Page 6: Recommended Operating Conditions And Absolute Maximum Ratings
The 73S12xxF Evaluation Board has two power supplies; 3.3 V and 5.0 V. Normally, the 5.0 V supply is tied to VPC IN on the 73S8009C board. The 73S8009C can supply the 3.3 V to the remainder of the system by configuring the jumpers accordingly. The 73S8009C VDD output can be disconnected from the rest of the evaluation board if desired and the 3.3 V supply on the 73S12xxF Evaluation Board can be... -

All the digital signals and power supply connections are made through 10-pin header connectors labeled J2 and J4 in Figure 2. Figure 2: 73S8009C Demo Board External Connectors Table 3 describes the pins for the J4 connector. -

Note: OFF_ACK must be set high to turn off. 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. - Page 11 (whether switch is nominally open or closed), and which of the card presence switch input of the 73S8009C is used. In this demo board, the switch is nominally open. The jumpers can be set in one of two ways: 1.

VBUS to VBAT when the VBUS power is removed. This switch over is done smoothly and does not cause any disruption of the operation of the 73S8009C and the VDD output supply. The operation of the ON/OFF switch is overridden when VBUS is applied. The 73S8009C and VDD output will always be active while the VBUS voltage is applied. -
Page 13: On/Off Switch Operation
When VBUS is removed, the latched state of the ON/OFF switch input dictates the state of the 73S8009C. If the switch input was not closed, the state of this latch will not change. It will be in the same state before the VBUS power was applied. If it has changed it holds the last toggled state. -
