Renesas Electronics Corporation Memory IDT71V3559S80PF8

The IDT71V3559S80PF8 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 the Zero Bus Turnaround (ZBT,Ñ¢) capability, which eliminates dead cycles between read and write operations, enhancing overall system performance. The device includes a burst counter that supports a four-word burst capability, allowing for efficient data transfer. It has individual byte write control for each of its four bytes, enabling selective data manipulation. The SRAM is packaged in a JEDEC standard 100-pin thin quad flatpack (TQFP), making it suitable for various applications requiring compact designs. Additional features include three chip enable pins for easy depth expansion, a clock enable (CEN) pin to suspend operations, and an optional JTAG interface for boundary scan testing. The IDT71V3559S80PF8 is suitable for commercial and industrial temperature ranges, making it versatile for different environments.
