AS7C4096A-20JIN

Memory IC Overview

The AS7C4096A-20JIN is a 4 Mbit (512K x 8) asynchronous static random-access memory manufactured by Alliance Memory. It operates with a supply 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 36-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 and has a maximum power supply current of 120 mA.

Memory IC Feature Summary

• Provides non-volatile data retention characteristics typical of SRAM architecture without requiring refresh cycles.
• Supports standard parallel data bus interfaces for direct connection to microprocessors and controllers.
• Engineered for reliable operation within extended industrial temperature environments.

Memory IC Applications

• Industrial control systems requiring robust memory solutions under varying thermal conditions.
• Embedded applications utilizing 5V logic families for data buffering and storage.
• Automotive electronics components operating within specified industrial temperature ranges.

Memory IC Procurement Notes

Verify the specific suffix 'JIN' corresponds to the SOJ-36 package and industrial temperature grade when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations prior to integration. Ensure that the 5V supply requirements align with the target system design specifications.

Memory IC Selection Notes

Select this component when a 512K x 8 organization is required with a 20 ns access speed in a 36-pin SOJ form factor. Compare against TSOP variants if leadless surface mounting is preferred over J-leads. Ensure the 5V operating voltage matches the system logic levels, as 3.3V versions exist within the same family but require different part numbers.

Memory IC Part Context

This part belongs to the AS7C4096A series of 4 Mbit SRAMs offered by Alliance Memory. The series includes various access speeds and package options, such as TSOP and SOJ configurations. The '20' indicates the 20 nanosecond access time, while 'JIN' specifies the industrial temperature range and SOJ packaging style.

Memory IC Replacement Considerations

Direct pin-compatible replacements include other AS7C4096A variants with identical electrical parameters but different packages, such as the AS7C4096A-20TIN (TSOP-II-44). Verify that substitute parts maintain the same 5V supply voltage and industrial temperature rating to ensure functional equivalence.
