M24LR64-R

64-Kbit dual interface EEPROM with password protection

Active

Description

The M24LR64-R device is a dual-interface, electrically erasable programmable memory (EEPROM). It features an I²C interface and can be operated from a V_CCpower supply. It is also a contactless memory powered by the received carrier electromagnetic wave. The M24LR64-R is organized as 8192 × 8 bits in the I²C mode and as 2048 × 32 bits in the ISO 15693 and ISO 18000-3 mode 1 RF mode.
