AT93C46A-10SU-2.7

Memory IC Overview

The AT93C46A-10SU-2.7 is a 1K-bit (64 x 16) serial EEPROM manufactured by Microchip Technology, housed in an 8-lead SOIC package. It operates within a supply voltage range of 2.7V to 5.5V and supports a clock frequency up to 2 MHz at 5V. The device features a three-wire serial interface with self-timed write cycles of 10 ms maximum. It provides high reliability with 1 million write cycle endurance and 100-year data retention.

Memory IC Feature Summary

• Three-wire serial interface for efficient communication
• Self-timed write cycle eliminates separate erase requirement
• High endurance and long-term data retention capabilities

Memory IC Applications

• Industrial applications requiring low-power operation
• Commercial systems needing non-volatile storage
• Automotive grade electronic components

Memory IC Procurement Notes

Verify the specific ordering suffix matches the required voltage range and package type. Confirm lead-free status if environmental compliance is mandatory. Check current availability as product lifecycles may change. Ensure the supplier provides official documentation for quality assurance.

Memory IC Selection Notes

Select this component when a 1K-bit capacity is sufficient for the application. Choose the 2.7V variant if the system operates strictly above that threshold. Consider the SOIC package for surface mount requirements. Verify interface compatibility with the host processor's serial controller.

Memory IC Part Context

This part belongs to the AT93C46A series of serial EEPROMs. It offers a compact memory solution for microcontroller-based designs. The series includes various package options and voltage variants to suit different design constraints.

Memory IC Replacement Considerations

Check for direct pin-compatible alternatives from the same manufacturer family. Verify electrical specifications match the original design requirements. Ensure software drivers are compatible with the replacement device's instruction set.
