MAX66020 is an ISO/IEC 14443 Type B-Compliant 1Kb Memory Fob that integrates 1024 bits of user EEPROM, a 64-bit unique identifier (UID) and a 13.56MHz RF interface.
The MAX66020 combines a 1024‑bit user EEPROM, a 64‑bit unique identifier (UID) and a 13.56 MHz ISO/IEC 14443 Type B RF interface in a plastic key fob. Memory is organized into 16 blocks of 8 bytes, with page‑level write protection and optional EPROM‑emulation mode. Communication uses the ISO/IEC 14443‑4 block transmission protocol, supporting data rates up to 847.5 kbps.
The device is powered entirely from the RF field, operates from –25 °C to +50 °C, and offers a minimum of 200 000 write/erase cycles and 40 years of data retention. It includes features such as AFI and CID support, a 10 ms maximum programming time, and a 1 ms power‑up time.
