DESCRIPTION
The
ISSI
IS61SP6436 is a high-speed, low-power synchro-
nous static RAM designed to provide a burstable, high-
performance, secondary cache for the i486, Pentium,
680X0, and PowerPC microprocessors. It is organized
as 65,536 words by 36 bits, fabricated with
ISSI
's advanced
CMOS technology. The device integrates a 2-bit burst counter,
high-speed SRAM core, and high-drive capability outputs into
a single monolithic circuit. All synchronous inputs pass through
registers controlled by a positive-edge-triggered single clock
input.
Write cycles are internally self-timed and are initiated by the
rising edge of the clock input. Write cycles can be from one to
four bytes wide as controlled by the write control inputs.
Separate byte enables allow individual bytes to be written.
BW1
controls DQP1 and DQ1-DQ8,
BW2
controls DQP2 and
DQ9-DQ16,
BW3
controls DQP3 and DQ17-DQ24,
BW4
controls DQP4 and DQ25-DQ32, conditioned by
BWE
being
LOW. A LOW on
GW
input would cause all bytes to be written.
Bursts can be initiated with either
ADSP
(Address Status
Processor) or
ADSC
(Address Status Cache Controller) input
pins. Subsequent burst addresses can be generated inter-
nally by the IS61SP6436 and controlled by the
ADV
(burst
address advance) input pin.
Asynchronous signals include output enable (
OE
), sleep mode
input (ZZ), clock (CLK) and burst mode input (MODE). A HIGH
input on the ZZ pin puts the SRAM in the power-down state.
When ZZ is pulled LOW (or no connect), the SRAM normally
operates after three cycles of the wake-up period. A LOW
input, i.e., GND
Q
, on MODE pin selects LINEAR Burst. A V
CCQ
(or no connect) on MODE pin selects INTERLEAVED Burst.
