IDT70V9359/49L
High-Speed 3.3V 8/4K x 18 Dual-Port Synchronous Pipelined Static RAM
Industrial and Commercial Temperature Ranges
Functional Description
The IDT70V9359/49 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 is independent 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 address counters for fast interleaved memory applications.
CE 0 = V IL and CE 1 = V IH for one clock cycle will power down the
internal circuitry to reduce static power consumption. Multiple chip enables
allow easier banking of multiple IDT70V9359/49's for depth expansion
configurations. When the Pipelined output mode is enabled, two cycles are
required with CE 0 = V IL and CE 1 = V IH to re-activate the outputs.

Depth and Width Expansion
The IDT70V9359/49 features dual chip enables (refer to Truth Table
I) in order to facilitate rapid and simple depth expansion with no require-
ments for external logic. Figure 4 illustrates how to control the varioius chip
enables in order to expand two devices in depth.
The IDT70V9359/49 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 various devices as required to allow for 36-bit or
wider applications.
