DESCRIPTION
The
ISSI
IS61SPD25632, IS61SPD25636, S61SPD51218,
IS61LPD25632, IS61LPD25636, and IS61LPD51218 are
high-speed, low-power synchronous static RAMs designed
to provide a burstable, high-performance, secondary cache for
the PentiumTM, 680X0TM, and PowerPCTM microprocessors.
The IS61SPD25632 and IS61LPD25632 are organized as
262,144 words by 32 bits and the IS61SPD25636 and
IS61LPD25636 are organized as 262,144 words by 36 bits.
The IS61SPD51218 and IS61LPS51218 are organized as
524,288 words by 18 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.
Byte write operation is performed by using byte write
enable (
BWE
).input combined with one or more individual
byte write signals (
BWx
). In addition, Global Write (
GW
)
is available for writing all bytes at one time, regardless of
the byte write controls.
Bursts can be initiated with either
ADSP
(Address Status
Processor) or
ADSC
(Address Status Cache Controller)
input pins. Subsequent burst addresses can be generated
internally and controlled by the
ADV
(burst address
advance) input pin.
The mode pin is used to select the burst sequence order,
Linear burst is achieved when this pin is tied LOW. Interleave
burst is achieved when this pin is tied HIGH or left floating.

Notes:
1. Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause perma-
nent damage to the device. This is a stress rating only and functional operation of the device at
these or any other conditions above those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for extended
periods may affect reliability.
2. This device contains circuity to protect the inputs against damage due to high static voltages or
electric fields; however, precautions may be taken to avoid application of any voltage higher than
maximum rated voltages to this high-impedance circuit.
3. This device contains circuitry that will ensure the output devices are in High-Z at power up.
