AS7C31026B-10TCN

Overview

The AS7C31026B-10TCN is a 1 Mbit asynchronous static random access memory (SRAM) manufactured by Alliance Memory. It features a storage organization of 64K words by 16 bits and operates with a maximum access time of 10 ns. The device supports a supply voltage range from 3 V to 3.6 V and draws a maximum current of 80 mA. It is housed in a 44-pin TSOP II package suitable for surface mount technology. The component is rated for commercial operating temperatures between 0°C and +70°C.

Feature Summary

• Provides high-speed data access with a 10 ns cycle time for efficient system performance.
• Utilizes a low-power CMOS technology to minimize energy consumption during operation.
• Offers flexible interface capabilities through standard parallel read and write control signals.

Applications

• Embedded systems requiring fast local data storage
• Industrial control units needing reliable memory buffers
• Consumer electronics devices utilizing 3.3V logic levels

Procurement Notes

Verify the specific suffix TCN confirms the TSOP II package and commercial temperature grade. Ensure the design accommodates the 44-pin footprint and 3.3V power requirements. Confirm RoHS compliance status if required by regional regulations. Check for moisture sensitivity level handling procedures during assembly.

Selection Notes

Select this part when a 16-bit wide memory interface is necessary within a compact surface-mount form factor. The 10 ns speed suits applications demanding rapid data retrieval without complex timing constraints. Consider the 3.3V operating voltage compatibility with modern digital logic families.

Part Context

This component belongs to the AS7C31026B series of 1 Mbit SRAMs. It shares architectural similarities with other members like the AS7C31025B but differs in pin count and organization. The series is designed for general-purpose memory applications where non-volatile retention is not required.

Replacement Considerations

Direct substitutes include the AS7C31026B-10JCN, which offers identical electrical specifications but utilizes a SOJ package instead of TSOP II. Verify mechanical clearance and soldering profile compatibility before swapping packages.
