Renesas Electronics Corporation Memory IDT71V2559S85PF

The IDT71V2559S85PF is a 3.3V synchronous SRAM with a memory configuration of 256K x 18 bits, designed for high-speed applications. It operates at a maximum 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 via the LBO pin. It supports individual byte write control for flexible data handling and has three chip enable pins for easy depth expansion. The IDT71V2559S85PF is packaged in a JEDEC standard 100-pin thin quad flatpack (TQFP), making it suitable for various applications requiring compact and efficient memory solutions.
