Overview
The IBM 043641WKAB-3 is a static random-access memory (SRAM) integrated circuit with a total capacity of 4 megabits. It utilizes High-Speed Transceiver Logic (HSTL) interface standards for high-speed data transfer. The device operates at a supply voltage of 3.3V and is designed for surface-mount assembly. It is housed in a 119-ball Ball Grid Array (BGA) package with dimensions of 17x7 mm, suitable for compact electronic designs requiring reliable volatile memory storage.
Feature Summary
- Utilizes HSTL interface technology for high-speed signal integrity
- Provides 4Mbit non-volatile storage capacity
- Designed for surface-mount integration via BGA packaging
Applications
- High-performance computing systems
- Server memory modules
- Network infrastructure equipment
Procurement Notes
Verify the manufacturer designation as IBM or authorized distributor Rochester Electronics. Confirm the specific suffix indicates the correct pinout and electrical characteristics. Ensure the component matches the 119-BGA physical form factor. Request original datasheets to validate the HSTL interface specifications and 3.3V operating requirements before finalizing acquisition.
Selection Notes
Select this component when an HSTL-compatible SRAM solution is required for 3.3V logic systems. The 119-BGA package necessitates PCB layouts supporting fine-pitch soldering. Consider the 4Mbit density relative to system bandwidth needs. Ensure thermal management strategies accommodate the surface-mount configuration during operation.
Part Context
This part belongs to the IBM SRAM family, specifically engineered for enterprise-grade applications. The 043641 series typically supports high-throughput data processing tasks. The HSTL standard ensures compatibility with contemporary high-speed digital interfaces found in server and networking hardware environments.
Replacement Considerations
The IBM 043641WKAB-5 is a documented variant within the same product line. Verify pin compatibility and electrical parameter alignment before substitution. Cross-reference datasheets to ensure functional equivalence in the target application.
