Overview
The IBM 043641WLAD-7 is a 4Mbit Static Random Access Memory (SRAM) integrated circuit. It utilizes CMOS technology and supports synchronous pipelined operation with self-timed late write capabilities. The device operates on a single differential HSTL clock signal at +3.3V. Available in a 119-ball BGA package measuring 17x7 mm, it offers memory organizations of 128K x 36 or 256K x 18 bits.
Feature Summary
- Synchronous pipelined architecture with self-timed late write functionality
- Single differential HSTL clock interface for high-speed data transfer
- Advanced 4Mbit SRAM design ensuring reliable data storage and retrieval
Applications
- High-performance computing systems requiring fast data access
- Network infrastructure equipment utilizing HSTL interfaces
- Embedded systems needing compact synchronous memory solutions
Procurement Notes
Verify the specific memory organization (128K x 36 or 256K x 18) required for your design, as this may vary by revision. Confirm the package type is indeed the 119-ball BGA (17x7mm). Ensure compatibility with +3.3V power supplies and HSTL clock standards. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.
Selection Notes
Select this component when a synchronous SRAM with HSTL interface is necessary. The 4Mbit capacity suits moderate data buffering needs. Consider the 119-BGA footprint for PCB layout constraints. Verify that the system supports single differential clocking and +3.3V logic levels before integration into the final hardware design.
Part Context
This part belongs to IBM's line of advanced SRAM devices designed for high-speed data processing. It complements other models like the 043641WLAD-5, which shares similar architectural features but may differ in specific organizational configurations or package variants within the same product family.
Replacement Considerations
The IBM 043641WLAD-5 is a related variant within the same series. Verify pinout compatibility and specific memory organization differences before substitution. Ensure the replacement matches the required HSTL voltage levels and package dimensions for direct interchangeability.
