Functional Description
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.
chronous bus interfacing. Counter enable inputs are also provided to stall
the operation of the address counters for fast interleaved
memory applications.
the internal circuitry to reduce static power consumption. Multiple chip
enables allow easier banking of multiple IDT70V3569s for depth expan-
sion configurations. Two cycles are required with CE
HIGH to re-activate the outputs.
