AS7C256A-12TIN

Overview

The AS7C256A-12TIN is a 256 Kbit (32K x 8) 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 12 ns. The device utilizes a parallel interface and is housed in a 28-pin TSOP I surface-mount package. It supports single data rate operations and is rated for an industrial temperature range from -40°C to +85°C, with a maximum supply current of 65 mA.

Feature Summary

Asynchronous SRAM architecture providing fast random access capabilities
Industrial-grade operational stability across extended temperature ranges
Surface-mount TSOP I packaging optimized for automated assembly

Applications

Industrial control systems requiring reliable volatile storage
Embedded applications utilizing 5V logic interfaces
Data buffering in consumer electronics manufacturing

Procurement Notes

Verify the specific suffix TIN against official datasheets to confirm the TSOP I package type and industrial temperature rating. Ensure compatibility with 5V power supplies and check moisture sensitivity levels before reflow soldering. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when a 12 ns access speed is required for 32K x 8 memory configurations in harsh environments. Compare against commercial variants if operating temperatures exceed standard limits. Validate pinout compatibility with existing PCB layouts designed for 28-pin TSOP packages.

Part Context

This part belongs to the AS7C256A series of asynchronous SRAMs. It shares architectural similarities with other members like the AS7C256A-15TCN but offers faster timing specifications. The series is designed for general-purpose memory applications where non-volatile retention is not required.
