AS5SS128K36
128K x 36 4Mb FLOW THROUGH ‘NO WAIT’
STATE BUS SYNCHRONOUS SRAM
FEATURES
• Available in Mil-Temp*, Enhanced* & Industrial Ranges
• 100 percent bus utilization
• No wait cycles between Read and Write1
• Internal self-timed write cycle
• Individual Byte Write Control
GENERAL DESCRIPTION
TheAS5SS128K36 is a high-speed, low-power synchronous
static RAM designed to provide a burstable, high-performance,
“no wait” state device for networking and communication ap-
plications. It is organized as 128K words by 36 bits fabricated
with Micross’ advanced CMOS technology.
• Single Read / Write control pin
• Clock controlled, registered address, data and
control
• Interleaved or linear burst sequence control using
MODE input
Incorporating a ‘no wait’state feature, wait cycles are eliminated
when the bus switches from read to write, or write to read.
This device integrates a 2-bit burst counter, high-speed SRAM
core, and high-drive capability outputs into a single monolithic
circuit.
• Three chip enables for simple depth expansion
and address pipelining
• Power down mode
• Common data inputs and data outputs
• CKE\ pin to enable clock and suspend operation
• Power Supply: VDD 3.3V ± 5%, VDDQ 3.3V/2.5V ± 5%
• JEDEC 100-Pin TQFP
• TQFP in copper lead frame for superior thermal
performance
All synchronous inputs pass through registers are controlled by
a positive-edge-triggered single clock input. Operations may
be suspended and all synchronous inputs ignored when Clock
Enable, CKE\ is HIGH. In this state the internal device will hold
their previous values.
All Read, Write and Deselect cycles are initiated by the ADV
input. When the ADV is HIGH the internal burst counter is
incremented. New external addresses can be loaded when
ADV is LOW.
• RoHs compliant options available
Write cycles are internally self-timed and are initiated by the
rising edge of the clock inputs and when WE\ is LOW. Separate
byte enables allow individual bytes to be written. A burst mode
pin (MODE) defines the order of the burst sequence. When tied
HIGH, the interleaved burst sequence is selected. When tied
LOW, the linear burst sequence is selected.
