CY7C09369V/89V
3.3 V 16 K / 32 K / 64 K × 16 / 18
Synchronous Dual-Port Static RAM
3.3 V 16 K / 32 K / 64 K × 16 / 18 Synchronous Dual-Port Static RAM
Features
■ True dual-ported memory cells that allow simultaneous access
of the same memory location
■ Six flow through/pipelined devices:
❐ 16 K × 16 / 18 organization (CY7C09269V/369V)
❐ 32 K × 16 organization (CY7C09279V)
❐ 64 K × 16 / 18 organization (CY7C09289V/389V)
■ Three modes:
❐ Flow through
❐ Pipelined
❐ Burst
■ Pipelined output mode on both ports allows fast 100 MHz
operation
■ 0.35 micron CMOS for optimum speed and power

■ High speed clock to data access: 7.5^[1], 9, 12 ns (max)
■ 3.3 V low operating power:
❐ Active = 115 mA (typical)
❐ Standby = 10 A (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 easy depth expansion
■ Upper and lower byte controls for bus matching
■ Automatic power down
■ Commercial and industrial temperature ranges
■ Pb-free 100-pin TQFP package available
