0436A4ACLAA-4F

Overview

The IBM 0436A4ACLAA-4F is a standard SRAM memory integrated circuit manufactured by IBM. It features a memory organization of 256K x 36 bits, resulting in a total density of 9,216,000 bits (approximately 9 Mbit). The device operates with a maximum access time of 2 nanoseconds and utilizes CMOS technology. It is housed in a 153-pin Plastic Ball Grid Array (PBGA) package, specifically identified as BGA-153. The component supports synchronous operation modes and is designed for high-performance data storage applications requiring wide I/O capabilities.

Feature Summary

• Supports synchronous pipeline mode operation for high-speed data processing
• Features wide 36-bit I/O interface for efficient data throughput
• Utilizes CMOS technology for low power consumption and high performance
• Includes boundary scan capabilities using a limited set of JTAG functions

Applications

• High-performance computing systems requiring fast static random access memory
• Network infrastructure equipment utilizing synchronous SRAM interfaces
• Industrial control systems needing reliable data storage with wide bus widths

Procurement Notes

Verify the specific suffix and pin configuration against the target system requirements to ensure compatibility with existing PCB layouts. Confirm that the 153-pin PBGA package matches the footprint specifications. Check for any RoHS compliance status updates or environmental restrictions relevant to the deployment region. Ensure that the synchronous interface timing parameters align with the system clock constraints.

Selection Notes

Select this component when a 256K x 36 organization is required for synchronous memory applications. Consider the 2ns access time for systems demanding rapid data retrieval. Evaluate the 153-pin BGA package size against available board space. Compare with other IBM SRAM variants like the 0418 series if different densities or organizations are needed.

Part Context

This part belongs to IBM's family of Synchronous Pipeline Mode SRAMs, which also includes models such as the IBM0418A8CXLBB and IBM0436A8CXLBB. These components share common design principles, including CMOS technology and support for both single and double data rate operations. The 0436A4ACLAA-4F specifically offers a 256K x 36 configuration, distinguishing it from 18-bit wide variants within the same product line.

Replacement Considerations

Direct substitutes may include other IBM SRAM parts with identical 256K x 36 organization and 2ns access time, such as the IBM0436A4CXLBB. Verify pinout compatibility and electrical characteristics before substitution. Cross-reference with distributor databases for equivalent parts from other manufacturers if IBM supply is unavailable.
