AS7C31025B-10JCNTR

Overview

The AS7C31025B-10JCNTR is a static random-access memory component manufactured by Alliance Memory. It features a storage capacity of 1 Mbit organized as 128K x 8 bits. The device operates with an access time of 10 ns and supports a parallel interface. It functions within a supply voltage range of 3 V to 3.6 V, with a maximum power consumption of 70 mA. The unit weight is specified at 10.274 g.

Feature Summary

• Asynchronous SRAM architecture for data retention without clock synchronization
• Single data rate (SDR) parallel interface for standard bus connectivity
• Surface-mount design compatible with automated assembly processes

Applications

• Embedded systems requiring non-volatile-like data buffering
• Industrial control units needing fast temporary data storage
• Consumer electronics utilizing surface-mount technology

Procurement Notes

Verify the suffix JCNTR against official datasheets to confirm tape-and-reel packaging specifications. Ensure compatibility with moisture sensitivity levels before reflow soldering. Cross-reference the manufacturer part number with distributor listings to validate authenticity and current production status.

Selection Notes

Select this component when a 1 Mbit asynchronous SRAM with 10 ns speed is required in a surface-mount package. Compare power consumption limits against system constraints. Verify that the 3.3V operating voltage aligns with the target circuit's logic levels and supply rails.

Part Context

This part belongs to the AS7C31025B series of high-speed SRAMs from Alliance Memory. It shares architectural similarities with other members like AS7C31025B-10JCN but differs in packaging format. The series targets applications demanding reliable, low-latency memory solutions in compact form factors.

Replacement Considerations

Check for pin-compatible alternatives such as AS7C31025B-10JCN if reel packaging is not strictly required. Verify electrical parameters match exactly before substitution.
