IDT71V65612
IDT71V65812
flatpack (TQFP), 119 ball grid array (BGA) and 165 fine pitch
ball grid array (fBGA)
The IDT71V65612/5812 are 3.3V high-speed 9,437,184-bit
(9 Megabit) synchronous SRAMS. They are designed to eliminate 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.
Description
Address and control signals are applied to the SRAM during one clock
cycle, and two cycles later the associated data cycle occurs, be it read
or write. The IDT71V65612/5812 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 IDT71V65612/5812
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.
The IDT71V65612/5812 has an on-chip burst counter. In the burst
mode, the IDT71V65612/5812 can provide four cycles of data for a single
address presented to the SRAM. The order of the burst sequence is
defined by the
LBO
input pin. The
LBO
pin selects between linear and
interleaved burst sequence. The ADV/LD signal is used to load a new
external address (ADV/LD = LOW) or increment the internal burst counter
(ADV/LD = HIGH).
The IDT71V65612/5812 SRAM utilize IDT's latest high-performance
CMOS process, and are packaged in a JEDEC Standard 14mm x 20mm
100-pin thin plastic quad flatpack (TQFP) as well as a 119 ball grid array
(BGA) and 165 fine pitch ball grid array (fBGA).
