128k X 36, 3.3v Synchronous Sram With Zbt Feature, Burst Counter And Flow-through Outputs

The IDT71V547 is a 3.3V high-speed 4,718,592-bit (4.5 Megabit) synchronous SRAM organized as 128K x 36 bits. It is designed to eliminate dead bus cycles when turning the bus around between reads and writes, or writes and reads. Thus it has been given the name ZBTTM, or Zero Bus Turn-around. Address and control signals are applied to the SRAM during one Clock cycle, and on the next Clock cycle, its associated data cycle occurs, be it read or write. The IDT71V547 contains address, data-in and control signal Registers The outputs are flow-through (no output data register). Output enable is the only asynchronous signal and CAN be used to disable the outputs at any given time. A Clock Enable (CEN) pin allows operation of the IDT71V547 to be suspended as long as necessary. All synchronous inputs are ignored when CEN is high and the internal device Registers will hold their previous values. There are three chip enable pins (CE1, CE2, CE2) that allow the user to deselect the device when desired. If any one of these three is not active when ADV/LD is low, no new memory operation CAN be initiated and any burst in progress is stopped. However, any pending data transfers (reads or writes) will be completed. The data bus will tri-state one cycle after the chip was deselected or write initiated. The IDT71V547 has an on-chip burst Counter In the burst mode, the IDT71V547 CAN provide four cycles of data for a single address presented to the SRAM The order of the burst sequence is defined by the LBO input pin. The LBO pin selects between linear and interleaved burst sequence. The ADV/LD signal is used to load a new external address (ADV/LD = LOW) or increment the internal burst Counter (ADV/LD = HIGH). The IDT71V547 SRAM utilizes IDT's high-performance, high-volume 3.3V CMOS process, and is packaged in a JEDEC Standard 14mm x 20mm 100-pin thin plastic quad flatpack (TQFP) for high board density.
