Description
The IDT71V35761/781 are high-speed SRAMs organized as
128K x 36/256K x 18. The IDT71V35761/781 SRAMs contain write, data,
address and control registers. Internal logic allows the SRAM to generate
a self-timed write based upon a decision which can be left until the end of
the write cycle.
The burst mode feature offers the highest level of performance to the
system designer, as the IDT71V35761/81 can provide four cycles of data
for a single address presented to the SRAM. An internal burst address
counter accepts the first cycle address from the processor, initiating the
access sequence. The first cycle of output data will be pipelined for one
cycle before it is available on the next rising clock edge. If burst mode
operation is selected (ADV=LOW), the subsequent three cycles of output
data will be available to the user on the next three rising clock edges. The
order of these three addresses are defined by the internal burst counter
and the
LBO
input pin.
The IDT71V35761/781 SRAMs 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.
