Additional Details:

The AT93C46R-10SU-2.7 operates at a maximum clock frequency of 1 MHz. It features a self-timed write cycle, which simplifies the programming process. The device offers high endurance with up to 1 million erase/write cycles and a data retention time of 100 years. The 8-lead SOIC package provides a compact footprint for space-constrained applications. It is well-suited for applications where occasional writing is needed with frequent reading, making it ideal for storing configuration parameters or identification information. The 2.7V operating voltage is useful in systems operating at lower voltages to reduce power consumption.
