SSTUG32866EC/G,518

Specialty Logic Overview

The NXP SSTUG32866EC/G,518 is a 1.8 V configurable registered buffer designed for DDR2 memory modules requiring parity checking. It supports a maximum clock frequency of 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.

Specialty Logic Feature Summary

• Configurable register supporting DDR2 up to 800 MT/s Registered DIMM applications
• Checks parity on the DIMM-independent data inputs
• Partial parity output and input allows cascading of two devices for correct parity error processing

Specialty Logic Applications

• 400 MT/s to 800 MT/s and higher DDR2 registered DIMMs desiring parity checking functionality

Specialty Logic Procurement Notes

Verify the specific suffix (G or S) against the required ambient temperature range, as the G variant is rated for 0 °C to +70 °C while the S variant extends to +85 °C. Confirm that the Pb-free SnAgCu solder ball compound meets the assembly process requirements. Ensure the LFBGA96 package footprint matches the design layout constraints.

Specialty Logic Selection Notes

Select this component when designing DDR2 RDIMMs that require integrated parity checking capabilities. The device offers flexibility through configuration pins to support either 25-bit 1:1 or 14-bit 1:2 topologies. Consider the thermal requirements when choosing between the EC/G and EC/S variants based on the operational environment.

Specialty Logic Part Context

This part belongs to the SSTU logic series from NXP Semiconductors. It is specifically engineered for high-speed memory applications, adhering to JEDEC standards for registered buffers. The device integrates parity logic directly into the buffer architecture to enhance data integrity in memory systems.
