Document #: 38-06054 Rev. *B
Revised April 18, 2005
Features
True dual-ported memory cells which allow simulta-
neous access of the same memory location
Two Flow-Through/Pipelined devices
— 16K x 36 organization (CY7C09569V)
— 32K x 36 organization (CY7C09579V)
0.25-micron CMOS for optimum speed/power
Three modes
— Flow-Through
— Pipelined
— Burst
Bus-Matching Capabilities on Right Port
(x36 to x18 or x9)
Byte-Select Capabilities on Left Port
100-MHz Pipelined Operation
High-speed clock to data access 5/6/8 ns
3.3V Low operating power
— Active = 250 mA (typical)
— Standby = 10
μ
A (typical)
Fully synchronous interface for ease of use
Burst counters increment addresses internally
— Shorten cycle times
— Minimize bus noise
— Supported in Flow-Through and Pipelined modes
Counter Address Read Back via I/O lines
Single Chip Enable
Automatic power-down
Commercial and Industrial Temperature Ranges
Compact package
— 144-Pin TQFP (20 x 20 x 1.4 mm)
— 144-Pin Pb-Free TQFP (20 x 20 x 1.4 mm)
— 172-Ball BGA (1.0-mm pitch) (15 x 15 x 0.51 mm)
