Functional Description[1]
The CY7C1480V33/CY7C1482V33/CY7C1486V33 SRAM integrates 2M x 36/4M x 18/1M × 72 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
• Supports bus operation up to 250 MHz
• Available speed grades are 250, 200 and 167 MHz
• Registered inputs and outputs for pipelined operation
• 3.3V core power supply
• 2.5V/3.3V I/O operation
• Fast clock-to-output times
   — 3.0 ns (for 250-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
• Single Cycle Chip Deselect
