SSTUB32S868CHLFT

Specialty Logic Overview

The SSTUB32S868CHLFT is a registered buffer integrated circuit manufactured by Renesas Electronics Corporation, designed for DDR2 memory applications. It features a 25-bit data width and operates within a supply voltage range of 1.7V to 1.9V. The component is housed in a 176-TFBGA package with dimensions of 6x15mm, designated as 176-CABGA. This surface-mount device supports high-speed signal buffering required for DDR2 system architectures.

Specialty Logic Feature Summary

• Configurable registered buffer architecture optimized for DDR2 memory interfaces
• Surface-mount construction utilizing a compact 176-pin TFBGA package
• Operates at standard DDR2 low-voltage levels between 1.7V and 1.9V

Specialty Logic Applications

• DDR2 memory subsystems requiring signal buffering
• High-speed digital logic circuits
• Server and workstation memory boards

Specialty Logic Procurement Notes

Verify the specific suffix 'CHLFT' against official Renesas documentation to confirm tape-and-reel packaging and lead-free status. Ensure compatibility with existing PCB footprints for the 176-CABGA package. Confirm that the 1.7V to 1.9V operating voltage aligns with the target system design requirements before procurement.

Specialty Logic Selection Notes

Select this component when designing systems specifically utilizing DDR2 memory technology. The 25-bit configuration must match the memory bus width requirements. Verify that the 176-TFBGA package size fits within the available board space constraints and thermal management capabilities of the final assembly.

Specialty Logic Part Context

This part belongs to the SSTUB series of registered buffers from Renesas Electronics. These components are specialized logic chips intended to improve signal integrity in high-speed memory designs. The SSTUB32S868 variant is specifically tailored for DDR2 applications, distinguishing it from buffers used in other memory standards like DDR3 or DDR4.

Specialty Logic Replacement Considerations

The datasheet notes pin-to-pin compatibility with the 74SSTUBF32868A. However, verify electrical specifications and availability, as the alternative may be marked as not recommended for new designs.
