SRAM Chip Sync Dual 3.3V 144K-Bit 8K x 18 20ns/9ns 100-Pin TQFP

The CY7C09349AV and CY7C09359AV are high-speed 3.3 V synchronous CMOS 4 K and 8 K × 18 dual-port static RAMs. Two ports are provided, permitting independent, simultaneous access for reads and writes to any location in memory. Registers on control, address, and data lines allow for minimal set-up and hold times. In pipelined output mode, data is registered for decreased cycle time.

• True dual ported memory cells which allow simultaneous access of the same memory location
• Two flow-through/pipelined devices
  • 8 K × 18 organization (CY7C09359AV)
• Three modes
  • Flow-through
  • Pipelined
  • Burst
• Pipelined output mode on both ports allows fast 67-MHz operation
• 0.35-micron complementary metal oxide semiconductor (CMOS) for optimum speed/power
• High-speed clock to data access 9 and 12 ns (max)
• 3.3 V low operating power
  • Active = 135 mA (typical)
  • Standby = 10 µA (typical)
• Fully synchronous interface for easier operation
• Burst counters increment addresses internally
  • Shorten cycle times
  • Minimize bus noise
  • Supported in flow-through and pipelined modes
• Dual chip enables for easy depth expansion
• Upper and lower byte controls for bus matching
• Automatic power-down
• Available in 100-pin thin quad flat pack (TQFP)
