The Microchip 47L64 is a 64-Kbit serial EERAM device that combines an SRAM memory core with hidden EEPROM backup. It features an 8,192 x 8-bit SRAM array and operates using a high-speed I²C interface with standard speeds of 1 MHz, 400 kHz, and 100 kHz. The device allows unlimited reads and writes, ensuring symmetrical timing for both operations. In terms of power consumption, the active current is a maximum of 1 mA, while the standby current is limited to 200 µA. The operating voltage range is between 2.7V and 3.6V, and it is rated for industrial temperature ranges from -40°C to +85°C. The device includes ESD protection exceeding 2,000V. The EERAM functionality allows for automatic data backup to EEPROM during power disruptions, with a minimum of 100,000 backup cycles and a data retention period of up to 100 years at 55°C. A small external capacitor is required for proper operation, facilitating the transfer of data during power loss events. This product is suitable for applications requiring reliable data retention and fast access speeds, making it a viable option for engineers looking for a robust memory solution.
