AS4C2M32SA-6TINTR

Memory IC Overview

The AS4C2M32SA-6TINTR is a 64 Mbit Synchronous Dynamic Random Access Memory (SDRAM) manufactured by Alliance Memory. It features a 2M x 32 organization and operates at a maximum clock frequency of 166 MHz with a 5.4 ns access time. The device supports a voltage range of 3.0 V to 3.6 V and functions within an industrial temperature range of -40°C to +85°C. It utilizes a TSOP-II package with 86 pins and is supplied in tape and reel format.

Memory IC Feature Summary

• Supports high-speed synchronous data transfer via standard SDRAM protocols
• Designed for reliable operation across extended industrial temperature ranges
• Integrates on-chip burst read/write logic for efficient memory access

Memory IC Applications

• Industrial control systems requiring robust memory performance
• Embedded computing platforms operating in harsh environments
• Telecommunications infrastructure equipment

Memory IC Procurement Notes

Verify the specific suffix 'INTR' confirms the tape and reel packaging configuration, as this differs from tray-packaged variants like the '-6TCN'. Ensure the component meets RoHS compliance requirements for your assembly process. Confirm that the industrial temperature grade (-40°C to +85°C) aligns with your system's thermal design specifications before finalizing procurement.

Memory IC Selection Notes

Select this part when a 32-bit wide interface is required for high-bandwidth applications. Compare against the AS4C2M32SA-7TCN if commercial temperature grades suffice, or consider the AS4C4M16SA series if a narrower 16-bit bus is acceptable for pin count reduction. Verify that the 166 MHz speed grade matches the target system clock constraints.

Memory IC Part Context

This component belongs to the AS4C2M32SA family of 64 Mbit SDRAMs. It shares architectural similarities with other members like the AS4C2M32SA-7TCN but differs in speed grade and packaging. The 'A Die' designation indicates a specific silicon revision used by Alliance Memory for this generation of DRAM products.

Memory IC Replacement Considerations

The AS4C2M32SA-7TCN serves as a compatible alternative offering commercial temperature operation. For identical electrical specifications but different packaging, verify availability of tray versions. Cross-reference with AS4C4M16SA devices only if 16-bit width adaptation is feasible.
