This is a user manual for the 73S8014BN demo board, which covers the usage methods, design considerations, hardware descriptions, etc. of the demo board.
The 73S8014BN demo board is a platform for evaluating the Teridian 73S8014BN smart card interface IC. It can be used as a stand‑alone board with an external microcontroller or as a daughter card for the 73S12xxF evaluation platform. The manual covers safety and ESD precautions, recommended operating conditions, and detailed hardware description.
Key sections include design considerations, jumper and connector descriptions, clock‑frequency configuration, an errata note about the 1.8 V output resistor, ordering information, and contact details for Maxim Integrated Products support.
| Supply Voltage Range (Vdd) | 2.7 V to 3.6 V DC |
|---|---|
| Ambient Operating Temperature | -40 °C to +85 °C |
| Pin Current | +100 mA |
| ESD Tolerance (Card Interface Pins) | +6 kV |
The recommended Vdd range is 2.7 V to 3.6 V DC, and Vec is 4.75 V to 5.5 V DC for ISO 7816 and EMV applications.
A minimum 20 kΩ load resistor to ground must be added to the VEO output when operating at 1.8 V.
Select the clock source with JP1 and set CLKDIV1 and CLKDIV2 pins; for example, CLKDIV1 = CLKDIV2 = 0 gives a frequency of SCLK/4.
Extreme caution is required when connecting live voltages, and the boards are ESD‑sensitive.
