AS7C1026B-15JCNTR

Overview

The AS7C1026B-15JCNTR is a 1 Mbit (64 K x 16) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a voltage range of 4.5 V to 5.5 V and features a maximum access time of 15 ns. The device supports a maximum supply current of 90 mA and functions in temperatures from -40°C to +85°C. It utilizes a parallel interface and is housed in a surface-mount SOJ-44 package, supplied in tape-and-reel format.

Feature Summary

• Provides high-speed asynchronous data access with a 15 ns cycle time for efficient system integration.
• Operates reliably across industrial temperature ranges (-40°C to +85°C) for demanding environments.
• Supports standard 3.3V or 5V logic levels via the specified voltage operating window.

Applications

• Industrial control systems requiring robust memory under varying thermal conditions
• Embedded computing modules utilizing parallel SRAM interfaces
• Telecommunications equipment needing fast asynchronous data buffering

Procurement Notes

Verify the specific suffix JCNTR against official datasheets to confirm the SOJ-44 package and tape-and-reel delivery method. Ensure the design accommodates the 4.5 V to 5.5 V power supply requirements and the 90 mA maximum current draw. Confirm that the industrial temperature rating aligns with the operational environment specifications before finalizing procurement.

Selection Notes

Select this component when a 64 K x 16 organization is required alongside 15 ns speed performance. It is suitable for designs necessitating an industrial temperature range and surface-mount assembly. Compare against other AS7C1026B variants if different packaging or commercial temperature ratings are preferred for cost optimization.

Part Context

This part belongs to the AS7C1026B series of 1 Mbit asynchronous SRAMs. It shares architectural similarities with other members like the AS7C1026B-15JIN but differs in packaging and reel configuration. The series is designed for general-purpose high-speed memory applications where non-volatile retention is not required during power loss.

Replacement Considerations

The AS7C1026B-15JIN serves as a tube-packaged alternative within the same family. Verify pin compatibility and electrical parameters before substitution. Other manufacturers may offer functionally equivalent parts, but direct pin-to-pin replacements require careful validation of timing and voltage specs.
