Additional Details:

The AT93C56AU3-10UU-1.8 operates at a maximum clock frequency of 1 MHz and offers a typical write cycle time of 5ms. It is organized as either 256 bytes x 8 bits or 128 words x 16 bits, selectable through the ORG pin. The device features a self-timed write cycle, freeing up the microcontroller for other tasks during the write operation. Its high endurance and data retention characteristics make it ideal for storing configuration data, calibration constants, and other critical information that needs to be preserved even when power is removed. The 8-lead UDFN package is designed for surface mount assembly and provides a small footprint, making it suitable for applications where board space is limited. The 1.8V operating voltage is especially advantageous in low-power systems, contributing to overall energy efficiency.
