AS7C4096A-20TIN

Memory IC Overview

The AS7C4096A-20TIN is a 4 Mbit (512K x 8) asynchronous static random-access memory (SRAM) manufactured by Alliance Memory, Inc. It operates within a voltage range of 3.0 V to 3.6 V and features a maximum access time of 20 ns. The device supports a maximum supply current of 110 mA and functions reliably across an industrial temperature range from -40°C to +85°C. It utilizes a parallel interface and is housed in a 44-pin TSOP-II surface-mount package.

Memory IC Feature Summary

• Provides high-speed asynchronous data access with a 20 ns cycle time for efficient system integration.
• Operates on a single 3.3 V power supply, ensuring compatibility with standard low-voltage logic families.
• Designed for industrial environments with extended temperature ratings spanning from -40°C to +85°C.

Memory IC Applications

• Industrial control systems requiring reliable non-volatile-like storage capabilities
• Embedded computing modules needing fast local data buffering
• Telecommunications equipment utilizing asynchronous memory interfaces

Memory IC Procurement Notes

Verify the specific suffix TIN indicates tape-and-reel packaging when ordering. Confirm the 3.3V operating voltage aligns with your system design, as this variant differs from 5V versions. Ensure the 44-pin TSOP-II footprint matches your PCB layout constraints before finalizing procurement.

Memory IC Selection Notes

Select this component when a 4 Mbit capacity with 20 ns speed is required in a compact surface-mount form factor. It is suitable for designs needing industrial temperature stability and 3.3V operation. Compare against the AS7C34096A series if lower power consumption at 3.3V is prioritized over the specific pinout or legacy compatibility of the 5V family.

Memory IC Part Context

This part belongs to the AS7C4096A series of 4 Mbit SRAMs. The '20' denotes the 20 ns access speed, while 'TIN' specifies the tape-and-reel packaging format. It is distinct from the AS7C34096A series, which typically operates at 3.3V, whereas this model is part of the broader 5V-compatible family adapted for specific voltage ranges.

Memory IC Replacement Considerations

Direct substitutes include other AS7C4096A variants with different speeds or packages, such as AS7C4096A-15TIN for faster access. Cross-series replacements like AS7C34096A require voltage level verification due to the 3.3V vs 5V difference.
