Memory IC datasheet and documents for AT93C66A-10TU-2.7-T

AT93C66A-10TU-2.7-T

Memory IC Overview

The AT93C66A-10TU-2.7-T is a 4096-bit serial electrically erasable programmable read-only memory (EEPROM) manufactured by Microchip Technology. 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 Chip Select, Shift Clock, Data Input, and Data Output pins. Internal organization is selectable between 512x8 or 256x16 via the ORG pin. It provides high reliability with 1 million write cycle endurance and 100-year data retention.

Memory IC Feature Summary

Supports user-selectable internal memory organization for flexible word width configurations
Features self-timed write cycles that eliminate the need for separate erase operations
Includes sequential read capability for continuous data streaming without dummy bits
Provides ready/busy status output on the data output pin during programming

Memory IC Applications

Industrial applications requiring low-power and low-voltage operation
Commercial applications needing non-volatile data storage
Systems utilizing three-wire serial communication interfaces
Devices requiring high-reliability memory with long data retention

Memory IC Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging if required for automated assembly. Confirm the '-2.7' designation matches the 2.7V minimum operating voltage requirement of the target system. Ensure the industrial temperature range aligns with environmental specifications. Check for current availability as this component may be subject to obsolescence notices.

Memory IC Selection Notes

Select this part when a 4Kbit capacity is needed with a three-wire interface. Choose the 2.7V version if the system operates strictly above 2.7V. Consider the AT93C66B series for new designs as the A-series is not recommended for new applications. Verify package compatibility with the PCB layout constraints.

Memory IC Part Context

This component belongs to the AT93C56A/66A family of serial EEPROMs from Atmel Corporation, now part of Microchip Technology. The AT93C66A variant specifically offers 4096 bits of storage. The datasheet notes that this product line is not recommended for new design and has been replaced by the AT93C56B or AT93C66B series.
