Description
HIGH-SPEED 2.5V
512/256/128K X 18 SYNCHRONOUS
IDT70T3339/19/99S
DUAL-PORT STATIC RAM
WITH 3.3V OR 2.5V INTERFACE
Features:
◆ True Dual-Port memory cells which allow simultaneous access of the same memory location
◆ High-speed data access – Commercial: 3.4 (200MHz)/3.6ns (166MHz)/ 4.2ns (133MHz)(max.) – Industrial: 3.6ns (166MHz)/4.2ns (133MHz) (max.)
◆ Selectable Pipelined or Flow-Through output mode ◆ Counter enable and repeat features ◆ Dual chip enables allow for depth expansion without
additional logic ◆ Interrupt and Collision Detection Flags ◆ Full synchronous operation on both ports
– 5ns cycle time, 200MHz operation (14Gbps bandwidth) – Fast 3.4ns clock to data out – Data input, address, byte enable and control registers
– 1.5ns setup to clock and 0.5ns hold on all control, data, and address inputs @ 200MHz
– Self-timed write allows fast cycle time ◆ Separate byte controls for multiplexed bus and bus
matching compatibility ◆ Dual Cycle D...
