AS7C1024B-12JCN

Overview

The AS7C1024B-12JCN is a 1 Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 12 ns. The device utilizes a parallel interface and is housed in a 32-pin Small Outline J-Lead package designed for surface-mount technology. It supports single data rate storage and functions reliably across a commercial temperature range from 0°C to +70°C, with a maximum power consumption of 100 mA.

Feature Summary

• Asynchronous operation with fast 12 ns access time for rapid data retrieval
• Single data rate architecture optimized for standard parallel bus interfaces
• Surface-mount construction in a compact 32-pin SOJ form factor

Applications

• Embedded systems requiring non-volatile-like speed without retention
• Industrial control units operating within commercial temperature limits
• Consumer electronics utilizing 5V logic families

Procurement Notes

Verify the specific suffix JCN confirms the 32-pin SOJ package and tube packaging configuration. Ensure the design accommodates the 4.5 V to 5.5 V supply requirement. Confirm humidity sensitivity handling procedures are implemented during assembly. Validate that the target application environment remains within the specified 0°C to +70°C operational range.

Selection Notes

Select this component when a 1 Mbit capacity is required with 12 ns performance at 5V logic levels. The SOJ-32 package suits applications needing surface-mount integration with specific footprint constraints. Consider alternative packages like TSOP if leadless mounting is preferred. Verify compatibility with existing board space and thermal management capabilities for the specified current draw.

Part Context

This part belongs to the AS7C1024B series of 1 Mbit SRAMs. It shares architectural similarities with other variants differing primarily in voltage tolerance or package type. The JCN suffix specifically denotes the physical housing and manufacturing batch characteristics defined by Alliance Memory for this commercial-grade memory solution.

Replacement Considerations

Direct substitutes include AS7C1024B-12TCN for TSOP-32 mounting or AS7C1024B-12JIN for industrial temperature ranges. Verify pinout compatibility before substitution. Voltage specifications must match the 5V requirement to ensure reliable operation.
