SSTUB32S868CHLF

Specialty Logic Overview

The SSTUB32S868CHLF is a registered buffer integrated circuit designed for DDR2 memory applications. Manufactured by Renesas Electronics Corporation, this component operates within a supply voltage range of 1.7V to 1.9V. It features a 25-bit data width and utilizes a 176-TFBGA package with dimensions specified as 176-CABGA (6x15). The device is intended for surface mount installation and functions as a dedicated logic chip to support high-speed data transmission in memory systems.

Specialty Logic Feature Summary

• Provides registered buffering functionality specifically optimized for DDR2 memory interfaces.
• Operates at low voltage levels between 1.7V and 1.9V for efficient power consumption.
• Utilizes a compact 176-pin TFBGA surface-mount package for space-constrained designs.

Specialty Logic Applications

• DDR2 memory subsystems requiring signal integrity enhancement
• High-speed digital logic circuits utilizing DDR2 protocols

Specialty Logic Procurement Notes

Verify the specific suffix 'CHLF' against official Renesas documentation to confirm exact temperature grade and lead-free status. Ensure compatibility with existing DDR2 controller specifications before procurement. Confirm package availability and handling requirements for the 176-CABGA form factor.

Specialty Logic Selection Notes

Select this component when designing DDR2-based systems requiring registered buffers. Consider the 1.7V-1.9V operating range and 176-pin footprint constraints. Evaluate thermal performance and signal integrity needs relative to standard unbuffered alternatives.

Specialty Logic Part Context

This part belongs to the SSTUB series of registered buffers from Renesas. These components are specialized logic chips used to drive memory loads. The SSTUB32S868 variant is tailored for DDR2 architectures, distinguishing it from buffers used in other memory standards like DDR3 or SDRAM.

Specialty Logic Replacement Considerations

Consult official Renesas substitution guides for pin-compatible alternatives. Verify electrical parameter equivalence for any cross-reference parts to ensure system stability.
