1.1
The TERIDIAN Semiconductor Corporation (TSC) 73S8014R/RN/RT Demo Board is a platform for
evaluating the TERIDIAN 73S8014R/RN/RT smart card interface ICs. It incorporates either the
73S8014R, the 73S8014RN or the 73S8014RT integrated circuit, and it has been designed to operate
either as a standalone 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 three parts differ
only slightly with regard to the control signals and the control function. These differences involve the VCC
and the clock divider control signals. The 73S8014R and 73S8014RN use the CMDVCC and 5V/#V
control signals to generate VCC (smart card supply voltage) at either 3V or 5V. The 73S8014RT
redefines the CMDVCC pin as CMDVCC% and 5V/#V as CMDVCC#. These redefined signals allow the
selection of 5V, 3V and 1.8V for VCC. See the applicable data sheet for further detail. The 73S8014R
uses the clock divider signals CLKDIV1 and CLKDIV2 to select between a divide by 1, 2, 4 and 8 for the
smart card CLK output. The 73S8014RN and 73S8014RT have been redefined to select between divide
by 1, 2, 4 and 6 to support NDS applications.
The board has been designed to comply with the NDS specification.

General
Safety and ESD Notes
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!
