1 Introduction

1.1 General

The Teridian Semiconductor Corporation (TSC) 73S8014BN demo board is a platform for evaluating the
Teridian 73S8014BN smart card interface IC. It incorporates the 73S8014BN integrated circuit, and it has
been designed to operate either as a stand-alone 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.
The 73S8014BN uses the CMDVCC and 5V/3V control signals to generate VCC (smart card supply
voltage) at 1.8V, 3V, or 5V. The 73S8014BN uses a single multilevel clock-divider signal, CLKDIV, to
select between a divide by 1, 2, 4, and 8 for the smart card CLK output. The demo board uses a resistor
divider on two pins to generate the multilevel signal for the clock divider. Refer to the 73S8014BN IC data
sheet for details.

The board has been designed to comply with the NDS specification.

1.2 Safety and ESD Notes

Connecting live voltages to the demo board system results in potentially hazardous voltages on the
boards.

Extreme caution should be taken when handling the demo boards after
connection to live voltages!

The demo boards are ESD sensitive! ESD precautions should be taken when
handling these boards!

1.4 Getting Started

Figure 2 shows the basic connections of the demo board.

 Power Supplies: Apply 3.3V to pin 10 of J4 and 5V to pin 10 of J2.
 Control signals to the device can be connected through J2 and J4 (see Figure 2 and the electrical

schematic Figure 4).

 Setting the clock frequency with an external clock source:

o Set JP1 to the SCLK setting.
o Apply clock source to pin 1 of J2.
o Apply 3.3V (1) or GND (0) to CLKDIV1 and CLKDIV2 pins allows the following:

- CLKDIV1 = CLKDIV2 = 0 clock frequency = SCLK/4

- CLKDIV1 = 0, CLKDIV2 =1 clock frequency = SCLK

- CLKDIV1 = 1, CLKDIV2 =0 clock frequency = SCLK/8

- CLKDIV1 = CLKDIV2 = 1 (or leaving both open) clock frequency = SCLK/2

 Setting the clock frequency using crystal Y1:

o Crystal included in the demo board is 12MHz (NDS applications can use up to 27MHz).
o Set JP1 to XTAL position.
o Apply 3.3V (1) or GND (0) to CLKDIV1 and CLKDIV2 pins allows the following:

- CLKDIV1 = CLKDIV2 = 0 clock frequency = 3MHz

- CLKDIV1 = 0, CLKDIV2 =1 clock frequency = 12MHz

- CLKDIV1 = 1, CLKDIV2 = 0 clock frequency = 1.5MHz

- CLKDIV1 = CLKDIV2 = 1 (or leaving both open) clock frequency = 6MHz

External clock source. JP1

must be in position SCLK

when use of an external

clock. Otherwise, pin

SCLK can be left open.
