AS7C1026B-15JCN

Overview

The AS7C1026B-15JCN is a 1 Mbit (64 K 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 is housed in a 44-pin Small Outline J-Lead (SOJ) package designed for surface mount technology. It supports a maximum power supply current of 90 mA and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Asynchronous parallel interface for direct system integration
• CMOS technology ensuring low power consumption
• Industrial-grade reliability with wide operating voltage tolerance

Applications

• Embedded systems requiring fast local data storage
• Industrial control units needing reliable volatile memory
• Communication equipment buffer applications

Procurement Notes

Verify the specific suffix JCN confirms the 44-pin SOJ package and commercial temperature rating. Confirm RoHS compliance status through official documentation before procurement. Ensure design-in compatibility with 5V logic levels. Check for any obsolescence notices or lifecycle changes directly from the manufacturer.

Selection Notes

Select this component when a 64K x 16 organization is required with 15 ns speed. Choose over TSOP variants if board space constraints favor the SOJ footprint. Verify that the 5V supply rail matches the system architecture. Consider humidity sensitivity handling during assembly processes.

Part Context

This part belongs to the AS7C1026B series of high-speed CMOS SRAMs. It shares architectural similarities with other members like the AS7C1026B-20 but offers faster access times. The SOJ package distinguishes it from the more common TSOP-II versions found in modern compact designs.

Replacement Considerations

AS7C1026B-15TCN: Same electrical specs but in TSOP-II package. AS7C1026B-20JCN: Slower 20 ns access time in identical SOJ package.
