Microchip Technology, Inc. Memory 93LC56-I/SN

The 93LC56-I/SN is a 2K-bit Microwire Serial EEPROM from Lingto Electronic Limited, designed for low voltage operation with a single supply voltage ranging from 2.5V to 5.5V. It features a low-power CMOS technology, with a typical active read current of 100 ¬µA and a standby current of 3 ¬µA at 2.5V. The memory organization can be configured as 256 x 8 bits or 128 x 16 bits, making it versatile for various applications. This EEPROM supports self-timed erase and write cycles, including automatic erase before write operations. It is equipped with power on/off data protection circuitry and provides a device status signal during erase/write cycles. The part is compliant with industry-standard 3-wire serial I/O and offers a sequential read function. It ensures a minimum of 1,000,000 erase/write cycles and has a data retention capability exceeding 200 years. The 93LC56-I/SN is available in an 8-pin SOIC package and operates within an industrial temperature range of -40¬8C to +85¬8C. It is important to note that this part is not recommended for new designs, and users are advised to consider the updated 93LC56C series instead.
