AS7C31026B-10JCN

Overview

The AS7C31026B-10JCN is a 1 Mbit (64 K x 16) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a supply voltage range of 3.0 V to 3.6 V and features a maximum access time of 10 ns. The device utilizes a parallel interface and is housed in a 44-pin Small Outline J-Lead (SOJ) package with a 400-mil footprint. It supports surface mount installation and functions reliably across a commercial temperature range from 0°C to +70°C, with a maximum power consumption of 80 mA.

Feature Summary

• Provides non-volatile data retention characteristics inherent to SRAM technology without requiring refresh cycles.
• Supports high-speed asynchronous read operations with a guaranteed 10 ns access time for rapid data retrieval.
• Operates on a single 3.3 V power supply, ensuring compatibility with standard low-voltage logic systems.

Applications

• Embedded storage in industrial control systems
• Cache memory buffers in consumer electronics
• Data logging modules in telecommunications equipment

Procurement Notes

Verify the specific suffix JCN confirms the SOJ-44 package and tube packaging format. Confirm the -10 speed grade matches system timing requirements. Ensure the commercial temperature rating aligns with the operational environment. Check RoHS compliance status against current regulatory standards. Validate pinout compatibility during PCB layout finalization.

Selection Notes

Select this component when a 64 K x 16 word width is required for data bus alignment. Choose the 10 ns speed grade for applications demanding faster cycle times than slower variants offer. Opt for the SOJ-44 package if board space constraints favor this form factor over TSOP or BGA options. Ensure the design accommodates the 3.3 V logic levels and associated power delivery requirements.

Part Context

This part belongs to the AS7C31026B series of 1 Mbit SRAMs. It shares architectural similarities with other members like the AS7C31025B but differs in organization and package type. The series is designed for general-purpose memory applications where fast random access is critical. It represents a standard solution for mid-density memory needs in embedded designs.

Replacement Considerations

AS7C31026B-12JCNTR offers identical organization and package but with a 12 ns access time and tape-and-reel packaging. AS7C31026B-10TIN provides the same electrical specifications in a TSOP-II-44 package. Verify pin-to-pin compatibility before substitution to ensure mechanical fit and electrical integrity.
