AS7C1026B-15TCN

Overview

The AS7C1026B-15TCN is a 1 Mbit (64K x 16) asynchronous static random access memory manufactured by Alliance Memory. It operates with a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 15 ns. The device utilizes CMOS technology and is housed in a 44-pin TSOP II package suitable for surface mount applications. It supports single data rate parallel interface operations within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Asynchronous operation with fast 15 ns access time
• CMOS technology for high reliability
• Single data rate parallel interface
• Commercial temperature range support

Applications

• General purpose data storage
• Buffer memory in embedded systems
• Cache memory applications

Procurement Notes

Verify the specific suffix TCN confirms the 44-pin TSOP II package and commercial temperature grade against official datasheets. Confirm RoHS compliance status through manufacturer documentation. Ensure design-in requirements match the 4.5V to 5.5V operating voltage and 15ns timing specifications before ordering.

Selection Notes

Select this component when a 64K x 16 organization is required with 15 ns speed. Compare against other AS7C1026B variants if industrial temperature ranges or different packaging options like SOJ are needed. Verify power consumption limits against system constraints, noting typical active current values from the datasheet.

Part Context

This part belongs to the AS7C1026B series of 1 Mbit SRAMs. It shares architectural similarities with other members of the family but differs in pin count and package type compared to 8-bit wide variants. The TSOP II form factor distinguishes it from leaded packages like SOJ found in industrial temperature versions.

Replacement Considerations

Check for AS7C1026B-15TJCN for industrial temperature range in SOJ package. Verify pin compatibility with other 44-pin TSOP II SRAMs from different manufacturers if sourcing alternatives.
