HIGH-SPEED 64K x 8
SYNCHRONOUS
DUAL-PORT STATIC RAM
PRELIMINARY
IDT709089S/L
Features:
x True Dual-Ported memory cells which allow simultaneous
access of the same memory location
x High-speed clock to data access
– Commercial: 9/12/15ns (max.)
x Low-power operation
– IDT709089S
Active: 950mW (typ.)
Standby: 5mW (typ.)
– IDT709089L
Active: 950mW (typ.)
Standby: 1mW (typ.)
x Flow-Through or Pipelined output mode on either port via
the FT/PIPE pin
x Counter enable and reset features
x Dual chip enables allow for depth expansion without
additional logic
x 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 9ns clock to data out in the Pipelined output mode
– Self-timed write allows fast cycle time
– 15ns cycle time, 66MHz operation in the Pipelined
output mode
x TTL- compatible, single 5V (±10%) power supply
x Industrial temperature range (–40°C to +85°C) is available
for selected speeds
x Available in 100-pin Thin Quad Flatpack (TQFP) package

NOTES:
1. Transition is measured 0mV from Low or High-impedance voltage with the Output Test Load (Figure 2).
3242 drw 08
2. OE is asynchronously controlled; all other inputs are synchronous to the rising clock edge.
3. ADS = VIL, CNTEN and CNTRST = VIH.
4. The output is disabled (High-Impedance state) by CE0 = VIH or CE1 = VIL following the next rising edge of clock. Refer to Truth Table 1.
5. Addresses do not have to be accessed sequentially since ADS = VIL constantly loads the address on the rising edge of the CLK; numbers are for reference use
only.
6. "X" denotes Left or Right port. The diagram is with respect to that port.
