• Includes write mistake prevention mechanisms such as write prohibition at power-on and low-voltage detection.
• Features address auto-increment during read operations and self-timed programming cycles.

Memory IC Applications

• Data storage in automotive electronic control units
• Configuration memory for industrial control systems
• Parameter storage in consumer electronics devices

Memory IC Procurement Notes

Verify the component status carefully before procurement, as this part is designated as Not Recommended for New Designs (NRND). Confirm that existing inventory or last-time-buy options align with long-term production requirements. Ensure compatibility with the TSSOP-B8 package dimensions and pinout specifications during integration planning.

Memory IC Selection Notes

Select this component only if the application requires Microwire interface compatibility and fits within the 1.7 V to 5.5 V operating voltage window. Consider the NRND status when evaluating long-term supply chain stability. Verify that the 512 x 16 bit organization meets specific data width requirements without necessitating additional logic for bit manipulation.

Memory IC Part Context

This EEPROM belongs to the BR93G series, which offers various densities from 1 kbit to 16 kbit. The series shares common package footprints and pin layouts across different capacities, facilitating design scalability. The Microwire interface provides a simple three-wire communication protocol suitable for space-constrained applications requiring reliable non-volatile storage.

Memory IC Replacement Considerations

Check for alternative parts within the same BR93G family that may have updated availability status while maintaining identical pinouts and functionality. Consult official substitution guides to ensure electrical and mechanical compatibility if transitioning away from this NRND component.
