• 3.3V –5 and +10 core power supply (VDD)

• 3.3V / 2.5V I/O supply (VDDQ)

• Fast clock-to-output times

— 2.6 ns (for 250-MHz device)

— 2.6 ns (for 225-MHz device)

— 2.8 ns (for 200-MHz device)

— 3.5 ns (for 166-MHz device)

— 4.0 ns (for 133-MHz device)

— 4.5 ns (for 100-MHz device)

• Provide high-performance 3-1-1-1 access rate

• User-selectable burst counter supporting Intel® Pentium® interleaved or linear burst sequences

• Separate processor and controller address strobes

• Synchronous self-timed writes

• Asynchronous Output Enable

• JEDEC-standard 100-pin TQFP package and pinout
