AS7C31025B-12JINTR

Overview

The AS7C31025B-12JINTR is a 1 Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a supply voltage range of 3.0 V to 3.6 V, with a maximum active current consumption of 65 mA. The device features a 12 ns access time and utilizes a parallel interface. It is housed in a 32-pin Small Outline J-Lead (SOJ) package designed for surface-mount technology. The component supports an extended industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Provides high-speed asynchronous data access with a 12 ns cycle time for efficient system integration.
• Operates on a single 3.3 V power supply, ensuring compatibility with standard low-voltage logic families.
• Engineered for reliability across wide thermal variations, supporting stable performance in demanding industrial environments.

Applications

• Industrial control systems requiring robust memory solutions under varying thermal conditions
• Telecommunications equipment utilizing standard 3.3 V logic interfaces
• Embedded computing modules needing compact surface-mount memory storage

Procurement Notes

Verify the specific suffix 'IN' confirms the industrial temperature grade (-40°C to +85°C) and 'TR' indicates tape-and-reel packaging. Confirm RoHS compliance status through official manufacturer documentation prior to final procurement decisions. Ensure design-in requirements match the SOJ-32 footprint dimensions and pinout configuration exactly.

Selection Notes

Select this component when a 128K x 8 organization is required alongside strict 3.3 V operation limits. The 12 ns speed class suits applications needing moderate-to-high throughput without complex synchronization. Consider the SOJ-32 package constraints against available board space and thermal dissipation capabilities in the target enclosure design.

Part Context

This part belongs to the AS7C31025B series of fast asynchronous SRAMs. It shares architectural similarities with other members like the AS7C31025B-12TJINTR but differs in temperature rating and packaging format. The series targets general-purpose memory needs where non-volatile retention is not required, offering immediate read/write access times.

Replacement Considerations

The AS7C31025B-12JIN serves as a tube-packaged alternative within the same electrical specification family. Verify pin compatibility and thermal ratings before substituting. No direct cross-manufacturer equivalents are confirmed in the provided source material.
