SSTUG32868ET/G,518

Specialty Logic Overview

The SSTUG32868ET/G,518 is a 1.8 V 28-bit 1:2 configurable registered buffer with parity for DDR2-1G RDIMM applications. It supports clock frequencies up to 450 MHz and operates within a supply voltage range of 1.7 V to 2.0 V. The device integrates the functionality of two JEDEC-standard registers in a single package, featuring permanently configured high output drive strength and additional chip select inputs. It is housed in a 176-ball TFBGA package measuring 6 mm x 15 mm.

Specialty Logic Feature Summary

• Integrates equivalent functionality of two JEDEC-standard DDR2 registers into a single package
• Includes parity checking function across 22 input data bits with open-drain error indication
• Permanently configured for high output drive strength to support heavy net loading conditions
• Features two additional chip select inputs for versatile enabling and disabling

Specialty Logic Applications

• High-density (e.g., 2 rank by 4) DDR2 registered DIMMs operating at 400 MT/s to 800 MT/s
• DDR2 Registered DIMMs requiring integrated parity checking functionality

Specialty Logic Procurement Notes

Verify component authenticity through authorized NXP channels. Confirm the specific suffix matches required temperature ranges and solder processes. Ensure compatibility with existing board layouts due to the 176-ball TFBGA footprint. Review datasheet specifications for signal integrity requirements before integration.

Specialty Logic Selection Notes

Select this component for designs requiring space savings by consolidating dual register functions. It is suitable for high-density memory modules needing enhanced drive strength and flexible chip select control. Verify that the system supports the required 1.8 V supply and differential clock inputs.
