Renesas Electronics Corporation Memory 71V3559S80PFG

The IDT71V3559S80PFG is a 3.3V synchronous SRAM with a memory configuration of 256K x 18 bits, designed for high-speed applications. It supports a maximum operating frequency of 100 MHz, providing a clock-to-data access time of 7.5 ns. This SRAM features Zero Bus Turnaround (ZBT,Ñ¢), which eliminates dead cycles between read and write operations, enhancing overall system performance. The device includes a burst counter that allows for four cycles of data output for a single address, with the burst order selectable between linear and interleaved modes via the LBO pin. It has three chip enable pins (CE1, CE2, CE2) for easy depth expansion and a single read/write control pin. The output is flow-through, meaning there is no output data register, which simplifies the control logic. The IDT71V3559S80PFG is packaged in a JEDEC standard 100-pin thin quad flatpack (TQFP), making it suitable for various applications requiring compact design. It operates with a power supply of 3.3V (¬±5%) and includes optional JTAG boundary scan functionality. This product is ideal for engineers looking for high-performance memory solutions in synchronous applications.
