Dual chip enables allow for depth expansion without
additional logic
Full synchronous operation on both ports
– 4ns setup to clock and 1ns hold on all control, data,
and address inputs
– Data input, address, and control registers
– Fast 6.5ns clock to data out in the Pipelined output mode
– Self-timed write allows fast cycle time
– 10ns cycle time, 100MHz operation in Pipelined output mode
Separate upper-byte and lower-byte controls for
multiplexed bus and bus matching compatibility
LVTTL- compatible, single 3.3V (±0.3V) power supply
Industrial temperature range (–40°C to +85°C) is
available for selected speeds
Available in a 128-pin Thin Quad Flatpack (TQFP) package
Green parts available, see ordering information
