AT93C46W-10SI-2.7

Memory IC Overview

The AT93C46W-10SI-2.7 is a 1K-bit serial electrically erasable programmable read-only memory (EEPROM) manufactured by Microchip Technology, formerly Atmel. 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 and offers user-selectable internal organization of either 128 x 8 or 64 x 16 bits. It is housed in an 8-lead JEDEC SOIC package with an industrial temperature rating of -40°C to +85°C.

Memory IC Feature Summary

• Supports self-timed write cycles without requiring separate erase operations
• Provides high reliability with one million write cycle endurance and 100-year data retention
• Features a simple three-wire serial communication interface for efficient data access

Memory IC Applications

• Industrial applications requiring low-power operation
• Commercial systems utilizing low-voltage logic
• Data storage for configuration parameters in microcontroller-based designs

Memory IC Procurement Notes

Verify the manufacturer origin as this component was originally produced by Atmel before acquisition by Microchip Technology. Confirm that the specific ordering suffix matches the required voltage range and package type. Ensure compliance with current environmental regulations such as RoHS status if applicable to your manufacturing process.

Memory IC Selection Notes

Select this component when a small capacity non-volatile memory is needed for storing calibration data or system settings. Consider the three-wire interface compatibility with your host processor. Evaluate the package constraints against available board space, noting the specific dimensions of the 8-lead SOIC form factor.

Memory IC Part Context

This part belongs to the AT93C46/56/66 family of serial EEPROMs. The '46' designation indicates a 1K-bit density. The 'W' suffix denotes a specific tape and reel packaging option, while 'SI' specifies the industrial temperature range and JEDEC SOIC package. The '-2.7' indicates the minimum operating voltage threshold.

Memory IC Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the same family. Verify electrical specifications and package dimensions before substituting with other manufacturers' parts.
