CY7C09269V/79V/89V
CY7C09369V/79V/89V
3.3V 16K/32K/64K x 16/18
Synchronous Dual-Port Static RAM
Features
■
Six flow through/pipelined devices:
❐ 16K x 16/18 organization (CY7C09269V/369V)
❐ 32K x 16/18 organization (CY7C09279V/379V)
❐ 64K x 16/18 organization (CY7C09289V/389V)
■
Three modes:
❐ Flow through
❐ Pipelined
❐ Burst
Burst counters increment addresses internally:
❐ Shorten cycle times
❐ Minimize bus noise
❐ Supported in flow through and pipelined modes
Dual chip enables easy depth expansion
■
■
Fully synchronous interface for easier operation
■
True dual-ported memory cells that allow simultaneous access
of the same memory location
■
■
■
3.3V low operating power:
❐ Active = 115 mA (typical)
❐ Standby = 10 μA (typical)
Upper and lower byte controls for bus matching
■
Automatic power down
■
Pipelined output mode on both ports allows fast 100 MHz
operation
■
Commercial and industrial temperature ranges
■
0.35 micron CMOS for optimum speed and power
■
Pb-Free 100-pin TQFP package available
■
High speed clock to data access: 6.5[1, 2], 7.5[2], 9, 12 ns (max)
