Description
The IDT71V632 is a 3.3V high-speed SRAM organized as 64K x 32
with full support of the Pentium鈩?and PowerPC鈩?processor interfaces.
The pipelined burst architecture provides cost-effective 3-1-1-1 second-
ary cache performance for processors up to 117MHz.
The IDT71V632 SRAM contains 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 extreme end of the write
cycle.
The burst mode feature offers the highest level of performance to the
system designer, as the IDT71V632 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 will be defined by the internal burst counter and the
LBO
input pin.
The IDT71V632 SRAM utilizes IDT's high-performance, high-volume
3.3V CMOS process, and is packaged in a JEDEC Standard 14mm x
20mm 100-pin thin plastic quad flatpack (TQFP) for optimum board density
in both desktop and notebook applications.
