AS7C256A-15TIN

Overview

The AS7C256A-15TIN is a 256 Kbit (32K x 8) asynchronous static random-access memory (SRAM) manufactured by Alliance Memory. It features a parallel interface with a maximum access time of 10 ns, despite the model suffix suggesting 15 ns performance. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 28-pin TSOP I package. It is rated for industrial temperature ranges from -40°C to +85°C.

Feature Summary

Asynchronous parallel SRAM architecture providing fast data access.

Applications

Industrial control systems requiring reliable volatile memory storage.

Procurement Notes

Verify the specific speed grade against datasheet specifications, as the part number indicates 15 ns but official listings specify 10 ns access time. Confirm the 28-TSOP I package dimensions match the design footprint. Ensure the 4.5V to 5.5V operating voltage aligns with the target system power rails. Check for RoHS compliance status if required by environmental regulations.

Selection Notes

Select this component when an industrial-grade SRAM with a 28-pin surface-mount package is required. It serves as a suitable alternative to through-hole DIP versions for space-constrained PCB designs. Consider the 10 ns access speed for applications needing faster response than standard 15 ns parts. Verify compatibility with 5V logic levels before integration into the circuit design.

Part Context

This component belongs to the AS7C256A series of high-speed SRAMs. It shares architectural similarities with other devices in the family but differs in package type and speed grading. The TSOP I variant offers a compact form factor compared to traditional DIP packages, facilitating automated assembly processes in modern electronics manufacturing.
