STMicroelectronics M24C64X-DRE 64-Kbit Serial I2C Bus EEPROM

STMicroelectronics M24C64X-DRE 64-Kbit Serial I2C Bus Electrically Erasable Programmable Memory (EEPROM) is organized as 8K x 8-bit. The STMicroelectronics M24C64X-DRE operates in a supply voltage from 1.7V to 5.5V with a clock frequency up to 1MHz, over an ambient temperature range from -40°C to +105°C. This EEPROM offers an additional 8-bit chip enable register for the configurable device address (CDA) and memory write protection feature. These two features enable the M24C64X-DRE to offer a configurable device address (authorized through software) to configure up to eight possibilities of chip enable address, and the write protection of the whole memory array, by setting (through software) the software write protection bit.
