1.4 Notes When Using a 73S12xxF Evaluation B oar d
The 73S12xxF Evaluation B oar d has two power supplies; 3.3 V and 5.0 V. Normally, t he 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 r est of the evaluation board i f desired and the 3.3 V supply on the 73S12xxF Evalu ation Board ca n be
used. See t he jump er descri ptions for more details.

4 Design Considerations
4.1 General Layout Rules
Follow these layout rules:
• Route I/O and auxiliary si gnals away from card interface signals.
• Keep C LK trace as sh or t as possib l e and with m i nimal bends i n the trace . If possible, keep routin g of
the CLK trace to one layer (avoid vias to other laye r s). Keep CL K trace away from other traces
especially RST, I/O and VCC. Filt er i ng of t he CLK trace is allowed for noise purposes. Up to 30 pF
to gr ound is allowed at the CLK pin of t he smart card conn ector. Al so, the zero Ω series resistor (R7)
can be replaced with a small resistor for ad diti onal fi l tering (no more than 100 Ω).
•Keep VCC tr ace as short as possibl e. Make tr ace a minimum of 0.5 mm thick. Also, keep VCC away
from ot her traces especial ly RST an d CL K.
• Keep R ST trace away from VCC and CLK traces. Up to 30 pF to grou nd is all owed for filtering.
• Keep 0.1 µF close to VD D pin of the device and directly take other end to g r ound.
• Keep 0.1 µF and 10 µF close to VPC pin of the d evice and directly take other en d to ground.
• Keep 4.7 µF close to VP pin of the device and d i r ectly take other end to ground.
• Keep 0.47 µF close to VCC pin of the smart card connector and direct l y take other end to ground.
4.2 Optimization for Compliance with EMV
Default configuration of the D emo boar d con tains a 27 pF capacitor (C 12) from the CLK pin of the smart
connector to ground and a 27 pF cap acitor (C 13) from the RST pin of the smart connector to ground.
These capacit ors serve as fi l ters for CLK and RST si gnals in the case of long traces or test equipm ent
pert ur ba ti o ns. T he capacitor on CLK r educes ringing on the trace, r educe s coupl i ng to ot her traces and
slo ws down the edg e of the CLK sign al . The capacitor on RST h elps the pertur bation specifi cation in a
noisy environment. Th e filter capacitor s can be useful in the EMV t est en vironment and have no effect on
NDS testing
C12 and C13 are represented on both sch em atic and BOM. These cap acitors ar e optional fil ter
capacitors on the smart card li nes CLK and RST, respectively for each card interface. These capacitors
may be adjusted ( value, n ot to exceed 30 p F) or removed to op timi ze performance in each specific
app l ication (PCB, card clock frequen cy , comp liance with applicable standard s etc).
4.3 Power Supply Input Configurations
4.3.1 USB Power
The USB confi guration use s the po we r supplied by the VBUS (4.4 to 5.5 V) and an opt ional VBAT input
that automatically switches from the VBUS to VBAT when the V BUS power is removed. This swi tch over
is d one smoot hly and does not cause any di srupt i on of th e operati on of th e 73S8009C and the VD D
output supply. The operat i on of t he ON/OFF switch is overridden when VBUS is applied. The 73S8009C
and VDD output will always be active while the VBUS voltage i s applied. The ON/OFF switch is enabled
when running off VBAT. When using this configuration, the VPC input should not be connected to an y
other power source.
4.3.2 Single Supply Power
The single supply configuration should leave the VBUS and VBAT pins unconnected and only connect
the power supply to VPC (2.7 to 6.0 V).
12 Rev. 1.3
UM_8009C_059 73S8009C Demo Board User Man ual
4.4 ON/OFF Switch Operation
The ON/OF F switch uses a pushbutton to toggle between tur ning the 73S8009C on and off. The switch
input contains a debounce circuit for protection. The 73S8009C defaults to the OFF stat e when the
power source is applied. When the 8009C is in the OFF state, a switch closure turns on the 73S8009C.
When the 73S8009C is ON, a swit ch cl osure does not turn off the 73S8009C by itself, but it activates the
OFF_REQ signal by setting it high. The 73S8009C does not shut off until the OFF_ACK is set high. The
purpose of this sequen ce is to al low the h ost pr ocessor to perform any necessary sh ut down tasks before
losing power. When the host is finished, it can set the OFF_ACK signal high to shut off the 73S8009C. If
ther e is no need for the host to perform any shutd own tasks, the OFF_ACK pin ca n be left open an d it
follows t he state of the OFF_REQ output by means of an i nternal resistor connection between the
OFF_REQ and OFF_ACK pins.
When power is applied to VBUS, the 73S8009C automat i cally turns on and the ON/OFF switch is
overidden. However, care must be taken as the ON_OFF in put is internally latched while th e VBUS
is ap plied . When VBUS is removed, the latched state of the ON/OFF switch input dictates the state
of the 73S8009C. If t he switch input was not closed, the state of t his latch will not chang e. It will b e
in th e same state before the VBUS power was applied. If it has changed it holds the last toggled
state. The OFF_REQ output follows this toggling. If the OFF_REQ output is high when VBUS
power is removed and the OFF_ACK is high, the 73S8009C shuts off.
Note: The resistors noted Ru and Rd in the schematic are n ot populated on the board. They can be
imple mented t o adj ust the feat ures of t he smart card reader.
