DESCRIPTION
The 2 Meg 'NLP/NVP' 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 64K words by 32 bits, 64K words by 36 bits, and 128K words by 18 bits, fabricated with ISSI's advanced CMOS technology. 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.

"X" means don't care. The rising edge of clock is symbolized by A continue deselect cycle can only be entered if a deselect cycle is executed first. WE = L means Write operation in Write Truth Table. WE = H means Read operation in Write Truth Table. 5. Operation finally depends on status of asynchronous pins (ZZ and OE).

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.
