The IS24C16A smart card is 2048 x 8 bits of EEPROM memory, organized into eight 16-byte pages. The pins of the IS24C16A are accessible through the gold plated contact pads embedded in the card, and when paired with the Smart Card Reader ( 32320) can be connected to the IO pins of a microcontroller. Copyright Parallax Inc. IS24C16A Smart Card ( 32322) v1.0 6/18/2010 Page 1 of 2 Connection Diagram In order to interface with the smart card, a smart card reader must be used. The diagram below demonstrates how to connect the Smart Card Reader ( 32320) from Parallax to your microcontroller for use with the example programs included on the IS24C16A product page. When inserting the smart card into the reader, be sure the gold contact pads are facing down.
