AS7C1026B-20TCNTR

Overview

The AS7C1026B-20TCNTR is a 1-Mbit (64K x 16) asynchronous static random-access memory manufactured by Alliance Memory. It operates within a voltage range of 4.5V to 5.5V and features a maximum access time of 20ns. The device utilizes a 44-pin TSOP-II surface-mount package and supports commercial operating temperatures from 0°C to +70°C. Maximum supply current is specified at 90mA, with parallel interface connectivity for data handling.

Feature Summary

• Asynchronous operation without clock dependency
• Single 5V power supply compatibility
• Surface-mount TSOP-II packaging

Applications

• Embedded system memory storage
• Industrial control units
• Consumer electronics devices

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging configuration against official manufacturer documentation. Confirm RoHS compliance status and humidity sensitivity level prior to procurement. Ensure the component matches the exact pinout and electrical specifications required by the target circuit design to prevent integration errors.

Selection Notes

Select this component when a 64K x 16 word width is required for 5V logic systems. The 20ns speed grade suits moderate-speed asynchronous applications. Consider the TSOP-II form factor for space-constrained printed circuit board layouts requiring surface-mount technology solutions.

Part Context

This part belongs to the AS7C1026B series of high-speed CMOS SRAMs. It provides non-volatile-like retention characteristics through volatile memory technology. The series offers various speed grades and package options to accommodate different performance and physical integration requirements in electronic designs.

Replacement Considerations

Check for direct cross-reference parts with identical 64K x 16 organization and 5V operation. Verify that any substitute maintains the same 44-pin TSOP-II footprint and 20ns or faster access time specifications.
