DESCRIPTION
ICSI's 8Mb SyncBurst Flowthrough SRAMs integrate a 512k x
18, 256k x 32, or 256k x 36 SRAM core with advanced
synchronous peripheral circuitry and a 2-bit burst counter.
Applications
The ICSI SyncBurst Flowthrough SRAM family employs highspeed ,low-power CMOS designs that are fabricated using an
advanced CMOS process to provide Level 2 Cache applications supporting Pentium and PowerPC microprocessors
originally, the device now finds application ranging from DSP
main store to networking chip set support.
Controls
All synchronous inputs pass through registers controlled by a
positive-edge-triggered single clock input.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.
Byte Write and Global Write
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 individualbyte write signals (BWx). In addition,
Global Write (GW) is available for writing all bytes at one time,
regardless of the byte write controls.
IOL/IOH Drive strength Options
The XQ pin allows selection between high drive strength (XQ
low) for multi-drop bus applications and normal drive strength
(XQ floating or high) point-to-point applications. See the Output
Driver Characteristics chart for details.
Snooze Mode
Low power (Snooze mode) is attained through the assertion
(High) of the ZZ signal, or by stopping the clock (CK). Memory
data is retained during Snooze mode.

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.
