Pin Description Summary
Description
The IDT71V3556/58 are 3.3V high-speed 4,718,592-bit (4.5 Mega-
bit) synchronous SRAMS. They are designed to elimnate dead bus
cycles when turning the bus around between reads and writes, or
writes and reads. Thus, they have been given the name ZBT
TM
, or
Zero Bus Turnaround.
Address and control signals are applied to the SRAMduring one
clock cycle, and two cycles later the associated data cycle occurs, be it
read or write.
The IDT71V3556/58 contain data I/O, address and control signal
registers. Output enable is the only asynchronous signal and can be used
to disable the outputs at any given time.
A Clock Enable (
CEN
) pin allows operation of the IDT71V3556/58
to be suspended as long as necessary. All synchronous inputs are
ignored when (
CEN
) is high and the internal device registers will hold
their previous values.
There are three chip enable pins (
CE
1
, CE
2
,
CE
2
) that allow the user
to deselect the device when desired. If any one of these three are not
asserted when ADV/
LD
is low, no new memory operation can be
initiated. However, any pending data transfers (reads or writes) will be
completed. The data bus will tri-state two cycles after chip is deselected
or a write is initiated.
