Mainstream contactless smart card IC

9.5 RF interface

The RF-interface is according to the standard for contactless smart cards

ISO/IEC 14443 A.

The carrier field from the reader is always present (with short pauses when transmitting),

because it is used for the power supply of the card.

For both directions of data communication there is only one start bit at the beginning of

each frame. Each byte is transmitted with a parity bit (odd parity) at the end. The LSB of

the byte with the lowest address of the selected block is transmitted first. The maximum

frame length is 163 bits (16 data bytes + 2 CRC bytes = 16 * 9 + 2 * 9 + 1 start bit).

9.6 Memory organization

The 1024 x 8 bit EEPROM memory is organized in 16 sectors with 4 blocks of 16 bytes

each. In the erased state the EEPROM cells are read as a logical “0”, in the written state

as a logical “1”.
