AS7C1024B-20TCN

Overview

The AS7C1024B-20TCN is a 1 Mbit (128K x 8) asynchronous static random access memory device manufactured by Alliance Memory. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 20 ns. The component utilizes a parallel interface and is housed in a 32-pin TSOP package suitable for surface mount technology. It supports single data rate operations and functions within a commercial temperature range of 0°C to +70°C, with a maximum power consumption of 80 mA.

Feature Summary

Asynchronous operation with fast 20 ns access time
Standard 5V CMOS technology for reliable performance
Surface-mountable TSOP-32 package design

Applications

General-purpose data storage in embedded systems
Cache memory buffers for microprocessors
Industrial control system data logging

Procurement Notes

Verify the specific suffix TCN confirms the TSOP-32 package and reel packaging format against official datasheets. Confirm RoHS compliance status and humidity sensitivity class prior to integration. Ensure supply voltage requirements match the 4.5V to 5.5V specification for stable operation.

Selection Notes

Select this component when a 128K x 8 organization is required with 20 ns speed at 5V logic levels. Compare against faster variants like the -12 speed grade if latency is critical. Consider the TSOP-32 footprint constraints versus other package options in the same family for board layout compatibility.

Part Context

This part belongs to the AS7C1024B series of high-speed CMOS SRAMs from Alliance Memory. It shares architectural similarities with other members of the family but differs in speed grade and package type. The B-series designation typically indicates standard performance characteristics within the manufacturer's asynchronous SRAM portfolio.
