IS61NVF102418

The 18 Meg 'NLF/NVF' product family IS61NVF102418 feature high-speed,low-power synchronous static RAMs designed to provide a burstable, high-performance, 'no wait' state, device for networking and communications applications. IS61NVF102418 They are organized as 256K words by 72 bits, 512K words by 36 bits and 1M 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 IS61NVF102418 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 IS61NVF102418 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 IS61NVF102418 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.
