AS7C256A-10JINTR

Overview

The AS7C256A-10JINTR is a 256 Kbit Static Random Access Memory (SRAM) manufactured by Alliance Memory, Inc. It features a memory organization of 32K x 8 bits and operates with a maximum access time of 10 ns. The device supports a parallel interface and requires a supply voltage between 4.5 V and 5.5 V. It is designed for industrial temperature ranges, functioning from -40°C to +85°C. The component is housed in a 28-pin Small Outline J-Lead (SOJ) package and utilizes surface mount technology.

Feature Summary

• Asynchronous SRAM architecture providing fast random access capabilities
• Industrial-grade operational temperature range for harsh environments
• Single 5V power supply operation compatible with standard logic levels

Applications

• Industrial control systems requiring reliable data retention
• Embedded applications within automotive electronics
• Telecommunications equipment operating in extreme temperatures
• Consumer appliances utilizing surface mount assembly processes

Procurement Notes

Verify the specific suffix 'IN' against official datasheets to confirm industrial temperature rating and SOJ packaging. Ensure voltage requirements match system design. Confirm RoHS compliance status through manufacturer documentation before integration into regulated products.

Selection Notes

Select this component when 10 ns access speed is required alongside industrial temperature stability. Compare against commercial variants if lower cost suffices for non-extreme environments. Verify pin compatibility with existing PCB footprints due to the specific SOJ form factor.

Part Context

This part belongs to the AS7C256A series of asynchronous SRAMs. It shares architectural similarities with other members like the AS7C256A-12JIN but offers faster performance. The series is designed for general-purpose memory storage in microcontroller-based systems.

Replacement Considerations

AS7C256A-12JIN serves as a slower alternative within the same package family.
