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 = 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.

2 Design Considerations
2.1 General Layout Rules
Keep the CLK signal as short as possible and with few bends in the trace. Keep route of the CLK trace to
one layer (avoid vias to other plane). Keep CLK trace away from other traces, especially RST and VCC.
Filtering of the CLK trace is allowed for noise purposes. Up to 30pF to ground is allowed at the CLK pin of
the smart card connector. Also, the 0 series resistor, R7, can be replaced for additional filtering (no
more than 100).
Keep the VCC trace as short as possible. Make trace a minimum of 0.5mm thick. Also, keep VCC away
from other traces especially RST and CLK.
Keep RST trace away from VCC and CLK traces. Up to 30pF to ground is allowed for filtering.
Keep 0.1F close to the V
Keep 0.1F and 10F close to the V
Keep 1.0F close to the V
2.2 Optimization for Compliance with NDS
Default configuration of the demo board contains a 27pF capacitor (C12) from the CLK pin of the smart
connector to ground and a 27pF capacitor (C13) from the RST pin of the smart connector to ground.
These capacitors serve as filters for the CLK and RST signals in the case of long traces or test equipment
perturbations. The capacitor on CLK reduces ringing on the trace, reduces coupling to other traces and
slows down the edge of the CLK signal. The capacitor on RST helps the perturbation specification in a
noisy environment. The filter capacitors can be useful in the EMV test environment and have no effect on
NDS testing.
C12 and C13 are represented on both the schematic and BOM. These capacitors are optional filter
capacitors on the smart card lines CLK and RST, respectively, for each card interface. These capacitors
can be adjusted (value, not to exceed 30pF) or removed to optimize performance in each specific
application (PCB, card clock frequency, compliance with applicable standards, etc.).

4 Demo Board Errata
The VCC output supply when operating at 1.8V requires a minimum 20k load resistor to ground for
output voltage stability. The demo board does not contain a footprint for this resistor. If using V
this resistor must be added to provide proper output voltage stability.
