Hardware Setup
STEP 1:
Insert a CryptoMemory device into
the SOIC socket
STEP 3:
Connect Clock and Data wires
Align PIN 0 of the SOIC package towards
the header-pins side of the adaptor board.
Use Black-Red patch cord
1. Connect the double-header end of the
Green-Yellow patch cord to the SCL-SDA
header pins of the adaptor board. Align
such that Green connects to SCL and
Yellow connects to SDA.
2. Connect the Green cord to your system
TWI clock.
3. Connect the Yellow cord to your system
TWI data.
Use Green-Yellow patch cord
1. Connect the double-header end of the
Green-Yellow patch cord to the SCL-SDA
header pins of the adaptor board. Align
such that Green connects to SCL and
Yellow connects to SDA.
2. Connect the Green cord to your system
TWI clock.
3. Connect the Yellow cord to your system
TWI data.
STEP 2:
Connect Power and Ground wires

Troubleshooting
1. Make sure CryptoMemory is properly inserted and aligned in the SOIC socket. The
correct orientation places PIN 0 of the SOIC package towards the adaptor board header
pins. When correctly oriented, holding the adaptor board with header pins towards self
should present the marking texts on the CryptoMemory package right side up.
2. Verify your hardware setup for accurate signal and power connections.
3. Make sure VCC is connected to a high-drive power supply.
4. Make sure your system meets pull-up resistor requirements on signal lines as defined in
CryptoMemory datasheets
5. Make sure to include noise filtering capacitors between Vcc and GND at the device
level, if working with a noisy system.
6. Read and Write CryptoMemory’s Memory Test Zone (MTZ) field to verify connectivity.
MTZ is free of all security requirements at all times.
