AS7C1026B-12JCN

Overview

The AS7C1026B-12JCN is a 1 Mbit (128K x 8) 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 12 ns. The device utilizes a parallel interface and is housed in a 32-pin SOJ package designed for surface mount technology. It supports single data rate operation and functions within a commercial temperature range of 0°C to +70°C, with a maximum power consumption of 100 mA.

Feature Summary

• Asynchronous parallel interface architecture
• Surface mount 32-pin SOJ packaging
• Single data rate operation mode

Applications

• Embedded system memory storage
• Industrial control equipment
• Consumer electronics devices

Procurement Notes

Verify the specific suffix JCN against official datasheets to confirm the 32-pin SOJ package configuration. Ensure that the 4.5 V to 5.5 V operating voltage aligns with your system design requirements. Confirm RoHS compliance status through manufacturer documentation before integration into regulated products.

Selection Notes

Select this component when a 1 Mbit capacity with 12 ns speed is required for 5V logic systems. The SOJ package suits applications needing surface mount assembly without the complexity of fine-pitch BGA options. Compare against TSOP variants if leaded pin compatibility or different thermal profiles are necessary for the target enclosure.

Part Context

This part belongs to the AS7C1026B series of high-speed SRAMs from Alliance Memory. It provides non-volatile-like retention characteristics while offering rapid read/write speeds suitable for cache applications. The series is engineered for reliability in commercial environments, supporting standard digital logic interfaces.

Replacement Considerations

Check for direct cross-references from other manufacturers offering identical 128K x 8 organization and 12 ns speed in SOJ-32 packages. Verify pinout compatibility and voltage tolerances before substituting.
