PRELIMINARY

IDT70T9359/49L

HIGH-SPEED 2.5V 8/4K x 18

SYNCHRONOUS PIPELINED

DUAL-PORT STATIC RAM

◆

ꢀeatures:

Full synchronous operation on both ports

– 4.0ns setup to clock and 0.5ns hold on all control, data, and

addressinputs

– Data input, address, and control registers

– Fast 7.5ns clock to data out in the Pipelined output mode

– Self-timedwriteallowsfastcycletime

– 12ns cycle time, 83MHz operation in Pipelined output mode

Separate upper-byte and lower-byte controls for

multiplexed bus and bus matching compatibility

LVTTL- compatible, single 2.5V (±100mV) power supply

Industrial temperature range (–40°C to +85°C) is

available for 66MHz

◆

True Dual-Ported memory cells which allow simultaneous

access of the same memory location

High-speed clock to data access

– Commercial:7.5/9/12ns(max.)

– Industrial:9ns (max.)

◆

Low-power operation

◆

– IDT70T9359/49L

Active:225mW(typ.)

◆

Standby: 1.5mW (typ.)

Flow-Through or Pipelined output mode on either port via

the FT/PIPE pins

Counter enable and reset features

Dual chip enables allow for depth expansion without

additional logic

◆

Available in a 100-pin Thin Quad Flatpack (TQFP) and 100-

pin fine pitch Ball Grid Array (fpBGA) packages.
