3.3 V 4 K/8 K × 18

Synchronous Dual Port Static RAM

3.3

V 4 K/8 K × 18 Synchronous Dual Port Static RAM

■ High-speed clock to data access 9 and 12 ns (max)

Features

■ 3.3 V low operating power

❐ Active = 135 mA (typical)

❐ Standby = 10 µA (typical)

■ True dual ported memory cells which allow simultaneous

access of the same memory location

■ Two flow-through/pipelined devices

❐ 4 K × 18 organization (CY7C09349AV)

❐ 8 K × 18 organization (CY7C09359AV)

■ Fully synchronous interface for easier operation

■ Burst counters increment addresses internally

❐ Shorten cycle times

❐ Minimize bus noise

■ Three modes

❐ Flow-through

❐ Pipelined

❐ Burst

❐ 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

■ Pipelined output mode on both ports allows fast 67-MHz

operation

■ 0.35-micron complementary metal oxide semiconductor

(CMOS) for optimum speed/power

■ Available in 100-pin thin quad flat pack (TQFP)
