Description

The IDT71V67602/7802 are high-speed SRAMs organized as

256K x 36/512K x 18. The IDT71V676/78 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 IDT71V67602/7802 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 IDT71V67602/7802 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 (fBGA).
