AS7C256A-10JIN

Overview

The AS7C256A-10JIN is a 256 Kbit (32K x 8) asynchronous static random-access memory manufactured by Alliance Memory, Inc. It operates within a voltage range of 4.5 V to 5.5 V and features a maximum access time of 10 ns. The component utilizes a parallel interface and is housed in a 28-pin Small Outline J-Lead (SOJ) package designed for surface mount technology. It supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Asynchronous SRAM architecture with parallel data interface
• Industrial-grade thermal stability for extended environments
• Surface-mount SOJ packaging for compact integration

Applications

• Industrial control systems requiring reliable volatile storage
• Embedded applications with strict temperature constraints
• Data buffering in high-speed parallel processing circuits

Procurement Notes

Verify the specific suffix 'JIN' against official datasheets to confirm the 28-pin SOJ package and industrial temperature rating. Ensure compatibility with 5V logic levels and check for RoHS compliance status prior to ordering. Confirm lead times as availability may vary.

Selection Notes

Select this component when a 10 ns access speed is required for 32K x 8 memory configurations in industrial settings. Compare against the AS7C256A-12JIN if slower speeds are acceptable or other variants if different packaging or voltage ranges are needed. Ensure board space accommodates the SOJ footprint.

Part Context

This part belongs to the AS7C256A series of 256 Kbit SRAMs. It shares architectural similarities with other variants like the AS7C256A-12JIN but offers faster 10 ns performance. The series provides non-volatile-free temporary storage solutions for microprocessors and digital signal processors.

Replacement Considerations

AS7C256A-12JIN serves as a verified substitute with identical pinout and capacity but a slower 12 ns access time.
