Multiple Protocol Contactless Reader IC
CL RC632
16 MIFARE^® HIGHER BAUDRATES
The MIFARE^® Classic system is specified with a fix Baud-rate of 106 kBaud for the communication on the
RF interface. ISO 14443 in the existing version also defines 106 kBaud at least for the initial phase of a
communication between PICC and PCD.
To speed up the communication between a terminal and a card to cover requirements for large data
transmission the CL RC632 supports the MIFARE^® higher baudrates communication in combination with e.g.
a µController IC like the MIFARE^® ProX.

The MIFARE^® Higher Baudrates’ concept will be described in the Application Note: ‘MIFARE^®
Implementation of Higher Baudrates’. This Application Note will cover also the integration a MIFARE^® Higher
Baudrates communication concept in current applications.
