The IDT71V3556S166PFG is a 3.3V synchronous SRAM featuring a 128K x 36 memory configuration, designed for high-speed applications with a maximum operating frequency of 166 MHz and a clock-to-data access time of 3.5 ns. This memory device incorporates Zero Bus Turnaround (ZBT) technology, which eliminates dead bus cycles during read and write operations, enhancing overall system performance. It includes a burst counter that allows for four cycles of data output for a single address, with the burst order selectable via the LBO pin. The device supports individual byte write control and features three chip enable pins for easy depth expansion. The IDT71V3556S166PFG is packaged in a JEDEC standard 100-pin thin quad flatpack (TQFP), making it suitable for various applications requiring efficient memory solutions. This SRAM is ideal for systems that demand high-speed data processing and minimal latency, particularly in commercial and industrial environments.
The 71V3556 3.3V CMOS Synchronous SRAM is organized as 128K x 36. 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 Turnaround. The 71V3556 contains data I/O, address and control signal registers.
