Specialty Logic Procurement Notes

This component is officially listed as obsolete and no longer manufactured by NXP USA Inc. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Buyers must confirm the specific revision level and physical condition of the units, as availability is limited to existing inventory rather than new production runs.

Specialty Logic Selection Notes

Engineers selecting this part should consider its specific compatibility with DDR2-800 standards and 1.8V logic levels. Due to its obsolete status, alternative solutions may be required for new designs. If continuing use is necessary, verify that the 176-TFBGA footprint and pinout match the existing PCB layout constraints and that the 1:2 buffering configuration meets the system's signal integrity requirements.
