If you’re facing obsolescence challenges with Micron’s Parallel NOR Flash devices, there’s a seamless path forward.

The PC28F256P33TFE from Alliance Memory is a direct replacement for the discontinued Micron model, allowing you to maintain your existing design without costly redesigns or requalification efforts.

:white_check_mark: Why choose Alliance Memory?
Alliance Memory has acquired the manufacturing rights for Micron’s legacy Parallel NOR Flash families (J3, P30, and P33). This ensures long-term availability and continuity, manufactured using the same proven 65nm process technology you relied on before.

Key Benefits:

  • :check_mark: Pin-to-pin compatibility with Micron’s original design
  • :check_mark: No redesign required
  • :check_mark: Same process technology (65nm) for consistent performance
  • :check_mark: Long-term supply assurance
