AS7C31025B-12JCNTR

Overview

The AS7C31025B-12JCNTR is a 1 Mbit (128K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates with a supply voltage range of 3.0 V to 3.6 V and features a maximum access time of 12 ns. The device supports single data rate (SDR) operation and has a maximum power consumption current of 65 mA. It is housed in a 32-pin Small Outline J-Lead (SOJ) package designed for surface-mount technology. The component is supplied in a reel format and is rated for an operating temperature range from -40°C to +85°C.

Feature Summary

• Asynchronous parallel interface for standard memory control
• Wide industrial operating temperature range for environmental stability
• Low-voltage 3.3V operation compatible with modern logic levels

Applications

• Industrial control systems requiring reliable data storage
• Embedded applications with space-constrained surface-mount designs
• Consumer electronics utilizing 3.3V logic families

Procurement Notes

Verify the specific suffix 'JCNTR' against the manufacturer's official datasheet to confirm the SOJ-32 package and reel packaging configuration. Ensure that the industrial temperature grade (-40°C to +85°C) meets the operational requirements of the target environment. Cross-reference the RoHS compliance status with current regulatory standards before finalizing procurement decisions.

Selection Notes

Select this component when a 128K x 8 organization is required within a 32-pin surface-mount footprint. The 12 ns speed class suits general-purpose asynchronous memory needs without high-frequency clocking constraints. Consider the industrial temperature rating if the application environment exceeds commercial limits, distinguishing it from lower-grade commercial variants.

Part Context

This part belongs to the AS7C31025B series of 1 Mbit SRAMs. The series offers various package options including TSOP and SOJ formats. The 'B' designation typically indicates the second generation or specific electrical characteristics within the family. The '12' suffix denotes the 12 nanosecond access time variant, providing a balance between speed and power efficiency for mid-range performance applications.

Replacement Considerations

Check for direct pin-compatible substitutes within the same AS7C31025B series, such as different package variants like AS7C31025B-12TCN or AS7C31025B-12TJINTR, ensuring voltage and temperature grades match.
