The 93AA66/SN is a 4Kbit low voltage serial Electrically Erasable Programmable Read-Only Memory (EEPROM) from Quarktwin Technology Ltd. It operates with a single supply voltage as low as 1.8V, making it suitable for low power applications. The device features a typical active read current of 70 ¬µA and a standby current of 2 ¬µA at 1.8V. The memory organization can be configured as 512 x 8 bits or 256 x 16 bits, depending on the ORG pin setup. This EEPROM supports self-timed erase and write cycles, including automatic erase functionality, and is designed with power on/off data protection circuitry. It utilizes an industry-standard 3-wire serial I/O interface and offers a sequential read function. The device is rated for 1,000,000 erase/write cycles and has a data retention period exceeding 200 years. It is available in an 8-pin SOIC package and operates within commercial and industrial temperature ranges of 0¬8C to +70¬8C and -40¬8C to +85¬8C, respectively. Engineers should note that this part is not recommended for new designs, and alternatives such as the 93AA66C are suggested.
