AS6C4008A-55SINTR

Overview

The AS6C4008A-55SINTR is a 4 Mbit (512 K x 8) asynchronous static random-access memory (SRAM) manufactured by Alliance Memory, Inc. It operates within a supply voltage range of 2.7 V to 3.6 V and features a maximum access time of 55 ns. The device utilizes a parallel interface and is housed in a 32-pin Thin Shrink Small Outline Package (TSOP II). It supports single data rate (SDR) operations and is designed for industrial temperature ranges, functioning reliably between -40°C and +85°C.

Feature Summary

• Asynchronous SRAM architecture with 512 K x 8 organization
• Low-power operation compatible with 2.7 V to 3.6 V supply rails
• Industrial temperature rating for extended environmental reliability
• Compact surface-mount TSOP II package design

Applications

• Embedded systems requiring volatile data storage
• Industrial control units operating in extreme temperatures
• Consumer electronics with low-voltage power constraints
• Automotive infotainment and instrumentation modules

Procurement Notes

Verify the specific suffix 'SINTR' against official datasheets to confirm the 32-pin TSOP II package and RoHS compliance status. Ensure the voltage range matches your system's 2.7V–3.6V requirement. Confirm availability as this component may be subject to discontinuation or limited stock depending on the manufacturer's lifecycle status.

Selection Notes

Select this component when a 4 Mbit capacity is required with fast 55 ns access times. It is suitable for designs needing low-power consumption under 3.3 V logic levels. Consider the TSOP II footprint for PCB layout compatibility. Verify that the parallel interface aligns with your microcontroller or FPGA memory controller capabilities.

Part Context

This part belongs to the AS6C4008 series of asynchronous SRAMs from Alliance Memory. It offers a balance of density and speed for general-purpose memory applications. The series is known for supporting standard parallel interfaces and providing reliable performance across various industrial and commercial environments.

Replacement Considerations

Check for direct pin-compatible substitutes such as the AS6C4008-55TIN or AS6C4008-55ZINTR if package differences are acceptable. Verify electrical specifications match exactly before substitution. Consult manufacturer obsolescence notices for long-term supply chain stability.
