AS7C1025B-15JCN

Overview

The AS7C1025B-15JCN 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 15 ns. The device utilizes a parallel interface and is housed in a 44-pin TSOP-II package designed for surface-mount technology. It supports single-data-rate operations and functions within a commercial temperature range of 0°C to +70°C, with a maximum power consumption of 90 mA.

Feature Summary

• Asynchronous parallel interface architecture
• Surface-mount TSOP-II packaging
• Single-data-rate operation mode

Applications

• Embedded data storage systems
• Industrial control units
• Consumer electronics devices

Procurement Notes

Verify the specific suffix JCN confirms the 44-pin TSOP-II package and commercial temperature rating. Confirm RoHS compliance status through official documentation. Check for end-of-life notices or obsolescence warnings prior to procurement decisions.

Selection Notes

Select this component when a 1 Mbit capacity with 15 ns speed is required in a compact surface-mount form factor. Ensure the design environment maintains a 5V logic level and operates within commercial temperature limits. Verify pin compatibility with existing PCB layouts requiring a 44-pin TSOP-II footprint.

Part Context

This part belongs to the AS7C1025B series of high-speed SRAMs. It provides non-volatile-like performance without the complexity of flash programming. The series is designed for applications requiring fast random access and low latency in embedded environments.

Replacement Considerations

Check for direct pin-compatible alternatives from Alliance Memory with updated packages. Evaluate generic SRAM equivalents only if electrical parameters match exactly. Verify availability of long-term supply agreements for critical production runs.
