Description
The MAX66020 combines 1024 bits of user EEPROM, a 64-bit unique identifier (UID), and a 13.56MHz RF interface (ISO/IEC 14443 Type B, Parts 2-4) in a plastic key fob. The memory is organized as 16 blocks of 8 bytes plus two more blocks for data and control registers. Four adjacent user EEPROM blocks form a memory page (pages 0 to 3). Memory protection features are write protection and EPROM emulation, which the user can set for each individual memory page. Memory access is accomplished through the block transmission protocol (ISO/IEC 14443-4), where requests and responses are exchanged through I-blocks once a device is in the ACTIVE state. The data rate can be as high as 847.5kbps. The reader must support a frame size of 19 bytes. The device supports an application family identifier (AFI) and a card identifier (CID). ISO/IEC 14443 functions not supported are chaining, frame-waiting time extension, and power indication.
