SSTUG32866EC/S,518

Specialty Logic Overview

The SSTUG32866EC/S,518 is a 1.8 V configurable registered buffer designed for DDR2 memory modules requiring parity checking. It supports operation at clock frequencies up to 550 MHz and operates within a supply voltage range of 1.7 V to 2.0 V. The device features a propagation delay of 1.4 ns and provides low-level output current of 8 mA and high-level output current of -8 mA. It is housed in a 96-ball LFBGA package with dimensions of 13.5 mm x 5.5 mm and an operating temperature range of 0 °C to +85 °C.

Specialty Logic Feature Summary

• Configurable register supporting DDR2 up to 800 MT/s applications
• Supports 25-bit 1:1 mode or 14-bit 1:2 mode via configuration pins
• Checks parity on DIMM-independent data inputs with open-drain error output
• Optimized pinout for high-density DDR2 module design

Specialty Logic Applications

• 400 MT/s to 800 MT/s DDR2 registered DIMMs
• Registered DIMMs requiring parity checking functionality
• DDR2-1G RDIMM applications

Specialty Logic Procurement Notes

Verify the specific suffix EC/S indicates an extended temperature range of 0 °C to +85 °C compared to the standard G variant. Confirm the Pb-free solder ball compound specification matches system requirements. Ensure the LFBGA96 package footprint aligns with PCB layout constraints before finalizing procurement orders.

Specialty Logic Selection Notes

Select this component when designing DDR2 registered DIMMs that require integrated parity checking capabilities. The device allows flexibility between 25-bit 1:1 and 14-bit 1:2 topologies through external configuration pins. Consider the 0 °C to +85 °C operating range if the application environment exceeds standard commercial limits. Verify compatibility with SSTL_18 signaling standards for data inputs.

Specialty Logic Part Context

This part belongs to the NXP SSTU series of configurable registered buffers specifically engineered for DDR2 memory systems. It integrates parity checking logic directly into the buffer architecture, reducing the need for external components. The device is optimized for signal integrity and speed in high-density memory module designs.

Specialty Logic Replacement Considerations

SSTUG32866EC/G is available as a substitute with a lower operating temperature range of 0 °C to +70 °C.
