CY7C1339G
4-Mbit (128K x 32) Pipelined Sync SRAM
[1]
Features Functional Description
• Registered inputs and outputs for pipelined operation The CY7C1339G SRAM integrates 128K x 32 SRAM cells with
advanced synchronous peripheral circuitry and a two-bit
• 128K × 32 common I/O architecture
counter for internal burst operation. All synchronous inputs are
• 3.3V core power supply (V )
DD gated by registers controlled by a positive-edge-triggered
Clock Input (CLK). The synchronous inputs include all
