IDT709089L

The IDT709089L is designed as a high-speed 64Kx8 bit synchronous dual-port RAM. The memory array utilizes dual-port memory cells to allow simultaneous access of any address from both ports. Registers on control, data, and address inputs provide minimal setup and hold times. The timing latitude provided by this approach allows systems to be designed with very short cycle times.

The features of the IDT709089L. (1)True dual-ported memory cells which allow simultaneous access of the same memory location. (2)High-speed clock to data access. (3)Low-power operation. (4)Flow-through or pipelined output mode on either port via the FT/PIPE pin. (5)Counter enable and reset features. (6)Dual chip enables allow for depth expansion without additional logic. (7)Full synchronous operation on both ports. (8)TTL- compatible, single 5V (±10%) power supply. (9)Industrial temperature range (-40°C to +85°C) is available for selected speeds. (10)Available in 100-pin thin quad flatpack (TQFP) package. Those are all the main features.

Some absolute maximum ratings of the IDT709089L have been concluded into several points as follow. (1)Its thermal voltage with respect to GND would be from -0.5V to 7.0V. (2)Its temperature under bias would be from -55°C to 125°C. (3) Its storage temperature range would be from -55°C to 125°C. (4)Its DC output current would be 50mA. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of the IDT709089L are concluded as follow. (1)Its input leakage current would be max 10uA. (2)Its output leakage current would be max 10uA. (3)Its output low voltage would be max 0.4V. (4)Its output high voltage would be min 2.4V. (5)Its input capacitance would be max 9pF. (6)Its output capacitance would be max 10pF at Vout=3dV. (7)Its recommended DC supply voltage would be min 4.5V and typ 5.0V and max 5.5V. (8)Its recommended ground would be 0V. And so on.
