AS7C256-20JC

Overview

The AS7C256-20JC is a high-performance CMOS static random-access memory (SRAM) manufactured by Alliance Memory, Inc. It features a storage capacity of 256 kbit organized as 32k x 8 bits. The device offers a maximum access time of 20 ns and operates on a single +5V power supply. It utilizes a parallel interface and is housed in a 28-pin Small Outline J-Lead (SOJ) package designed for surface mount installation.

Feature Summary

Provides high-speed read and write access to the internal memory array
Operates reliably on a single positive voltage supply
Utilizes CMOS technology for efficient performance

Applications

Embedded systems requiring fast data buffering
Industrial control applications with standard voltage requirements
General-purpose digital logic circuits needing volatile memory

Procurement Notes

Verify the specific suffix and package configuration against official datasheets before procurement. Confirm that the 28-pin SOJ form factor matches the target PCB footprint. Ensure the operating temperature range aligns with the intended environmental conditions. Cross-reference manufacturer part numbers to avoid counterfeit components.

Selection Notes

Select this component when a 256 kbit SRAM with 20 ns speed is required in a 28-pin SOJ package. It serves as a direct replacement for legacy parts from manufacturers such as Cypress Semiconductor. Consider the single 5V supply constraint and industrial temperature capabilities during system design.

Part Context

This part belongs to the AS7C256 series of asynchronous SRAMs from Alliance Memory. These devices are designed as drop-in replacements for older generation memory ICs. The series maintains compatibility with standard microcontroller and DSP interfaces while offering improved availability compared to discontinued original equipment manufacturer parts.
