AS7C31026B-20JCN

Overview

The AS7C31026B-20JCN is a 1 Mbit (64 K x 16) asynchronous static random-access memory manufactured by Alliance Memory. It operates on a single 3.3 V power supply with a maximum voltage of 3.6 V and a minimum of 3.0 V. The device features a 20 ns access time and draws a maximum operating current of 65 mA. It utilizes a parallel interface and is housed in a 44-pin SOJ package designed for surface-mount technology. The component supports standard dynamic random-access memory operations within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Asynchronous operation with fast access times for general-purpose memory applications
• Single 3.3 V power supply compatibility for low-voltage system integration
• High-density 1 Mbit storage organized as 64 K words by 16 bits
• Surface-mount 44-pin Small Outline J-Lead package for compact board layouts

Applications

• General-purpose data storage in embedded systems
• Cache memory buffers in microprocessor-based designs
• Industrial control equipment requiring commercial temperature stability
• Consumer electronics utilizing 3.3 V logic families

Procurement Notes

Verify the exact suffix against manufacturer documentation, as variations may indicate different packaging or temperature grades. Confirm RoHS compliance status through official datasheets prior to integration. Ensure ESD protection protocols are followed during handling due to CMOS sensitivity. Cross-reference pinouts with the specific revision to avoid layout errors.

Selection Notes

Select this component when a 64-bit wide data path is required at 3.3 V. Compare against TSOP alternatives if leaded packages are preferred for reworkability. Evaluate power consumption limits against system battery constraints. Verify that the 20 ns speed meets the target clock cycle requirements of the host processor.

Part Context

This part belongs to the AS7C31026B series of high-speed SRAMs from Alliance Memory. It shares architectural similarities with other members of the B-series but differs in organization and voltage specifications. The SOJ package variant is distinct from the more common TSOP II options found in the same product family.
