IDT70V9089/79S/L
High Speed 3.3V 64/32K x 8 Synchronous Dual-Port Static RAM Industrial and Commercial Temperature Ranges
Functional Description
The IDT70V9089/79 provides a true synchronous Dual-Port Static
RAM interface. Registered inputs provide minimal set-up and hold times
on address, data, and all critical control inputs. All internal registers are
clocked on the rising edge of the clock signal, however, the self-timed
internal write pulse s ndependent of the LOW to HIGH transition of the clock
signal.
An asynchronous output enable is provided to ease asynchronous
bus interfacing. Counter enable inputs are also provided to stall the
operation of the counter registers for fast nterleaved memory applications.
A HIGH on

or a LOW on CE

for one clock cycle will power down
the internal circuitry to reduce static power consumption. Multiple chip
enables allow easier banking of multiple IDT70V9089/79's for depth
expansion configurations. When the Pipelined output mode s enabled, two
cycles are required with

HIGH to re-activate the
outputs.

Depth and Width Expansion
The IDT70V9089/79 features dual chip enables (refer to Truth Table
I) in order to facilitate rapid and simple depth expansion with no require-
ments for external ogic. Figure 4 llustrates how to control the various chip
enables in order to expand two devices in depth.
The IDT70V9089/79 can also be used in applications requiring
expanded width, as indicated in Figure 4. Since the banks are allocated
at the discretion of the user, the external controller can be set up to drive
the input signals for the varioius devices as required to allow for 16-bit or
wider applications.
