SUMMARY DESCRIPTION

The LRI512 is a contactless memory, powered by an externally transmitted radio wave. It is fully

compliant with the ISO15693 recommendation for radio-frequency power and signal interface.

The LRI512 contains 512 bits of Electrically Erasable Programmable Memory (EEPROM). The

memory is organized as 16 blocks of 32 bits.
