AS7C4096A-20TCN

Memory IC Overview

The AS7C4096A-20TCN is a 4 Mbit (512K x 8) asynchronous static random-access memory manufactured by Alliance Memory, Inc. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 20 ns. The device utilizes a parallel interface and is housed in a 44-pin TSOP II package suitable for surface mount technology. It supports single data rate operations and is designed for commercial temperature environments.

Memory IC Feature Summary

• Provides non-volatile-like rapid data retention characteristics typical of SRAM architecture
• Supports standard parallel data bus interfaces for direct microcontroller or processor connection
• Utilizes a compact thin small-outline package for efficient board space utilization

Memory IC Applications

• Embedded systems requiring fast local data storage
• Industrial control units needing reliable memory buffers
• Consumer electronics with moderate speed data processing requirements

Memory IC Procurement Notes

Verify the specific suffix TCN confirms the 44-pin TSOP II package and commercial temperature rating. Ensure the voltage supply matches the 4.5V to 5.5V requirement. Confirm RoHS compliance status if required by your manufacturing standards. Check for moisture sensitivity level handling instructions during assembly.

Memory IC Selection Notes

Select this component when a 512K x 8 organization is required with 20 ns access speeds. It is suitable for designs operating at 5V logic levels. Consider alternative packages like SOJ if through-hole mounting is necessary. Verify that the thermal performance meets the commercial temperature range specifications.

Memory IC Part Context

This part belongs to the AS7C4096A series of high-speed SRAMs from Alliance Memory. It shares architectural similarities with other variants in the family but differs in package type and speed grade. The TCN suffix specifically denotes the surface-mount TSOP II form factor.

Memory IC Replacement Considerations

Direct substitutes include AS7C4096A-20JCN for through-hole applications. Other speed grades such as AS7C4096A-15 are available for faster timing requirements. Ensure pin compatibility and voltage levels match before substitution.
