0436A4ACLAB-50

Overview

The IBM 0436A4ACLAB-50 is a standard synchronous SRAM with a density of 4 Mbit, organized as 128K x 36. It utilizes CMOS technology and operates in single data rate synchronous mode. The component features a 256-pin BGA package and supports commercial temperature ranges.

Feature Summary

• Synchronous operation with self-timed late write capability for full data coherency
• CMOS technology implementation for low power consumption
• Supports single differential HSTL clock and 0.95V V REF input levels

Applications

• High-speed data buffering in server architectures
• Cache memory systems requiring low latency access
• Embedded storage solutions in industrial computing equipment

Procurement Notes

Verify the specific suffix designation to ensure compatibility with system voltage requirements and pin configurations. Confirm that the supplier provides traceability documentation for original IBM Microelectronics manufacturing. Ensure the component meets the required commercial temperature operating range specifications before integration into final assemblies.

Selection Notes

Select this component when a 128K x 36 organization is required for synchronous SRAM applications. Consider the BGA package constraints for PCB layout design. Evaluate the need for HSTL interface compatibility against other available logic families in the target system architecture.

Part Context

This part belongs to the IBM 0436 series of synchronous SRAMs. It shares architectural similarities with the IBM0436A4CXLBB-4 but differs in package type and specific operational parameters. The series is designed for high-performance memory applications requiring fast access times and reliable data retention.

Replacement Considerations

Direct substitutes include the IBM0436A4CXLBB-4 for similar functional performance. Verify pinout compatibility and electrical characteristics before swapping components in existing designs.
