93LC76AT-I/OT

Memory IC Overview

The Microchip Technology 93LC76AT-I/OT is an 8Kbit serial Electrically Erasable PROM (EEPROM) featuring a dedicated 1024 x 8-bit memory organization. It utilizes low-power CMOS technology and operates within a supply voltage range of 2.5V to 5.5V. The device supports a maximum clock frequency of 3 MHz and provides data retention exceeding 200 years with endurance up to 1,000,000 erase/write cycles. It is housed in a 6-lead SOT-23 package and complies with Industrial temperature specifications ranging from -40°C to +85°C.

Memory IC Feature Summary

• Supports industry-standard 3-Wire Microwire serial interface for efficient pin usage
• Includes power-on/off data protection circuitry to prevent corruption during voltage transitions
• Features self-timed erase and write cycles with automatic ready/busy status polling via the DO pin

Memory IC Applications

• Low-power nonvolatile memory storage in embedded systems
• Configuration data retention in industrial control devices
• Parameter storage in consumer electronics requiring small form factors

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and package type. Confirm RoHS compliance and lead-free finish requirements against current manufacturing standards. Ensure the selected variant aligns with the intended operating voltage and environmental conditions for the target application design.

Memory IC Selection Notes

Select this component when a fixed 8-bit word size is required without external configuration pins. The 'A' designation indicates a dedicated 1024 x 8 organization, distinguishing it from 'C' versions which offer selectable word sizes. Choose the 'I' suffix for industrial temperature ranges and 'E' for automotive applications.

Memory IC Part Context

This part belongs to the 93XX76 family of 8Kbit serial EEPROMs manufactured by Microchip Technology. The family includes variants with different memory organizations and voltage ranges, such as the 93AA76 series for lower voltage operation and the 93C76 series for higher voltage requirements. All members share common serial interface protocols and functional architectures.

Memory IC Replacement Considerations

Direct replacements include other 93LC76 variants with compatible packages and electrical characteristics, such as the 93LC76AT-E/OT for extended temperature ranges or the 93LC76AT-I/SN for SOIC packaging. Verify pin compatibility and voltage specifications before substitution.
