AS7C256A-20TIN

Overview

The AS7C256A-20TIN is a 256 Kbit (32K x 8) asynchronous static random-access memory (SRAM) 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 20 ns. The device utilizes a parallel interface and is housed in a 28-pin TSOP I surface-mount package. It supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

Asynchronous parallel SRAM architecture for general-purpose data storage
Industrial temperature rating for reliable operation in harsh environments
Surface-mount TSOP I packaging for compact circuit board integration

Applications

Industrial control systems requiring robust memory solutions
Embedded applications with standard 5V logic interfaces
Data acquisition modules needing fast random access

Procurement Notes

Verify the specific suffix 'TIN' against official datasheets to confirm the 28-pin TSOP I package and industrial temperature grade. Ensure supply chain partners provide RoHS compliance documentation. Confirm that the 5.5V operating voltage aligns with the target system's power rails before procurement.

Selection Notes

Select this component when a 256 Kbit capacity with 20 ns speed is required in a 28-pin surface-mount form factor. It serves as a suitable alternative to legacy 5V SRAMs in designs transitioning from through-hole packages. Consider the industrial temperature range if the application environment exceeds commercial limits.

Part Context

This part belongs to the AS7C256A series, which offers various speed grades and package options. The '20' indicates the 20 ns access time, while 'TIN' specifies the TSOP I package and industrial temperature range. It complements other variants like the 10ns or 12ns versions for different performance requirements.

Replacement Considerations

Check for direct pin-compatible alternatives such as the AS7C256A-10TIN for faster access times or AS7C256A-15TIN for potentially lower cost options. Verify that any substitute maintains the same 5V supply requirement and TSOP I footprint.
