1.0 Introduction
Sycard Technology's CFextend 165 CompactFlash to PC Card-16 extender card allows a standard 68-pin PC Card-16
card to be plugged into a 50-pin CompactFlash socket. The major use of this product is for companies to test their PC
Card products prior to converting them over to the CompactFlash form factor.
• Push button switches simulates card removal/insertion cycle
• Low profile enclosure compatible with all CompactFlash hosts
• 4 layer construction to insure low noise environment
• All 50 pins available as test points
• Both I/O and memory mode signals clearly marked
• Vcc can be isolated through jumper blocks for current measurements
• Surface mount resistors can be added to any signal line
• Current protection device protects host from Vcc to ground shorts
• Vcc LEDs indicate 3.3V or 5V operation
• Convenient grounding posts for scope probes or other test equipment
2.0 Using the CFextend 165
Using the CFextend 165 is relatively straightforward. The extender card is inserted into the desired slot in the host
system. Then the 68 pin PC-Card 16 is inserted into the card connector.
Caution: Insertion and removal of the extender and PC Card should be done with care. The CF Card's
fragile connectors may be broken or bent if improper force is used. Both card and extender should be
inserted straight without any lateral movement or force. Proper care and use of the extender card will
insure years of trouble free operation.

2.1 The CompactFlash to PC Card-16 Interface
The CFextend 165 allows the user to test a PC Card-16 device in a CompactFlash socket. Since the CompactFlash
interface is a subset of the PC Card-16 interface, it is expected that many PC Cards will not operate in a CF
environment. The following table outlines the differences between the CompactFlash and PC Card-16 interface and
how the extender handles the differences.

2.2 Test points
All 50-pins of the interface are available to probe through clearly marked headers. The headers are standard 0.1”
dual row headers with 0.025” posts designed to accept a wide variety of test probes and cable assemblies. The test
points are clearly labeled with the CompactFlash signal designations.
2.3 Power Indicators
Two LED power indicators display the status of the socket’s Vcc. The PWR LED indicates that power is applied to
the board. When both the PWR LED and the 5V LED are lit, a Vcc of greater than approximately 3.5V is present.
When only the PWR LED is lit, the Vcc is at a level of less than 3.5V.
Note: The power LEDs are designed to indicate the presence of power on the Vcc supply pins. The LEDs do
not provide an accurate measurement of Vcc. Use a voltmeter to determine the actual operating voltage.

2.4 Current Measurements
The Vcc power bus may be isolated from the PC Card-16 socket through the jumper block labeled JP3. A current
meter can be inserted to measure card current consumption. For critical power measurements, it may be desirable to
disable the current protection device (V1). V1 may be taken out of the circuit by installing JP4.
Caution: Care must be taken to insure that the current measuring device is inserted before turning on power
to the host socket. Improper power sequencing may cause a damaging latchup condition.
2.5 Using the Card Detect switches
CFextend 165 includes two micro switches (SW1 and SW2)which can be used to momentarily interrupt the CD1- and
CD2- signals. By interrupting the CD1- and CD2- signals, a card removal/insertion cycle can be simulated.
To test the operation of the Card Detect switches, be sure that your CF Card Software drivers are loaded.
Momentarily press both of the Card Detect switches. Most software drivers will issue a removal beep followed by an
insertion beep. The software may also remove power from the socket when the card is removed.

2.6 Termination Area
An area with SMT resistors is located between the test points and the PC Card-16 connector. These resistor pads
allow access to all CF Card signals. By cutting the shorting trace on each one of these resistor pads, the user can
isolate a signal. The user may also add series resistors to any signal. When shipped from the factory, the resistor
pads are shorted with PCB traces. In order to insert series resistor, these traces must be cut prior to soldering the
resistor to the board. Figure 2.4-1 and 2.4-2 illustrate the termination areas located on both sides of the CFextend
board. Use this guide when making modifications to the board, since the silk-screen designations may be difficult to
read.
