Functional Description[1]
The CY7C1339F SRAM integrates 131,072 x 32 SRAM cells with advanced synchronous peripheral circuitry and a two-bit counter for internal burst operation. All synchronous inputs are gated by registers controlled by a positive-edge-triggered Clock Input (CLK).

FEATUREs
• Registered inputs and outputs for pipelined operation
• 128K × 32 common I/O architecture
• 3.3V core power supply

   — 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)
