The IDT71V65703/5903 contain address, data-in and control signal
registers. The outputs are flow-through (no output data register). 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 IDT71V65703/5903
tobesuspendedaslongasnecessary.Allsynchronousinputsareignoredwhen
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 is 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 one cycle after the chip is deselected or a write
is initiated.
The IDT71V65703/5903 have an on-chip burst counter. In the burst
flatpack (TQFP), 119 ball grid array (BGA) and 165 fine pitch
ball grid array (fBGA).
Description
The IDT71V65703/5903 are 3.3V high-speed 9,437,184-bit
(9 Megabit) synchronous SRAMs organized as 256K x 36 / 512K x 18.
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.
Address and control signals are applied to the SRAM during one clock
Pin Description Summary
mode, the IDT71V65703/5903 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 IDT71V65703/5903 SRAMs utilize IDT’s latest high-performance
CMOS process and are packaged in a JEDEC Standard 14mm x 20mm 100-
pin plastic thin quad flatpack (TQFP), 119 ball grid array (BGA) and a 165
fine pitch ball grid array (fBGA).
