LRI512 数据手册 ( 数据表 ) - STMicroelectronics

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.
