FEATURES
DESCRIPTION
• 100 percent bus utilization
The 36 Meg 'NLF/NVF' product family feature high-speed,
low-power synchronous static RAMs designed to provide
a burstable, high-performance, 'no wait' state, device for
networking and communications applications. They are
organized as 1M words by 36 bits and 2M words by 18
bits, fabricated with ISSI's advanced CMOS technology.
• No wait cycles between Read and Write
• Internal self-timed write cycle
• Individual Byte Write Control
• Single Read/Write control pin
• Clock controlled, registered address, data and control
• Interleaved or linear burst sequence control using MODE input
• 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
• JEDEC 100-pin TQFP package
• Power supply:
NVF: Vdd 2.5V (± 5%), Vddq 2.5V (± 5%)
NLF: Vdd 3.3V (± 5%), Vddq 3.3V/2.5V (± 5%)
• Industrial temperature available
• Lead-free available
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.
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.
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.

Notes:
1. Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent 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.
