The 93LC46B-I/MS is a 1Kbit low-voltage serial EEPROM that operates within a voltage range of 2.5V to 5.5V. It features a 16-bit word size and is designed for low-power applications, making it suitable for nonvolatile memory needs. The device supports self-timed erase and write cycles, including an automatic erase function before writing all data. It has a data retention capability exceeding 200 years and can endure up to 1,000,000 erase/write cycles. This EEPROM utilizes an industry-standard 3-wire serial I/O interface and includes a device status signal to indicate readiness. It is available in various package types, including 8-lead MSOP, and is RoHS compliant. The operating temperature ranges for the 93LC46B-I/MS include industrial (-40¬8C to +85¬8C) and automotive (-40¬8C to +125¬8C) specifications, making it versatile for different applications.
