SRT512 is a 13.56MHz short-range contactless memory chip with 512-bit EEPROM and anticollision functions from ST
The SRT512 is a contactless memory chip powered by an externally transmitted radio wave at 13.56 MHz. It contains a 512-bit user EEPROM organized into 16 blocks of 32 bits and features an anticollision mechanism for detecting and selecting tags within range of a reader. The device is designed for short-range applications requiring reusable products.
