SSTUAF32868AHLF

Specialty Logic Overview

The SSTUAF32868AHLF is a 28-bit, 1:2 configurable registered buffer designed for DDR2 memory applications. It operates within a supply voltage range of 1.7V to 1.9V and supports commercial temperature grades from 0°C to 70°C. The device features SSTL_18 compatible data inputs and outputs, with LVCMOS support for control signals like CSGEN and RESET. Packaged in a 176-ball CABGA (6x15mm) format, it integrates parity checking capabilities to ensure data integrity during transmission.

Specialty Logic Feature Summary

• Integrates parity check functionality to verify data accuracy by generating error signals upon detection of mismatches.
• Supports low-voltage operation between 1.7V and 1.9V to reduce power consumption while maintaining signal stability.
• Allows configuration switching between Register A and Register B via the C input pin for flexible system integration.

Specialty Logic Applications

• DDR2 memory module buffering
• High-speed data bus interconnects
• System-on-chip memory interface design

Specialty Logic Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified partners. Confirm package marking and lot codes against official datasheets. Check for moisture sensitivity level compliance prior to soldering. Ensure storage conditions meet specified humidity limits to prevent damage before reflow processing.

Specialty Logic Selection Notes

Select this component for designs requiring 28-bit wide data paths with built-in error checking. Ensure the system power rail strictly maintains the 1.7V to 1.9V operating window. Verify that the PCB layout accommodates the 176-CABGA footprint dimensions. Consider thermal management requirements for commercial grade temperature ranges.

Specialty Logic Part Context

This part belongs to the SSTUAF32868 family of registered buffers manufactured by Renesas Electronics. It is specifically engineered to drive high-capacitance loads associated with DDR2 memory architectures. The device replaces older buffer solutions by offering integrated parity logic and lower voltage operation standards.

Specialty Logic Replacement Considerations

The 74SSTUB32868ZRHR from Texas Instruments is documented as a similar replacement option. Verify pin compatibility and electrical specifications before substitution. Note that the original SSTUAF32868AHLF is marked as obsolete in some catalogs.
