Working Principles

The IDT71V3557SA85BGG is a synchronous SRAM that operates based on an external clock signal. It uses a high-speed interface to provide fast data access and retrieval capabilities. The memory cells are organized in a 256K x 36 bit configuration, allowing for large storage capacity. The device operates at a voltage of 3.3V and supports clock frequencies up to 117 MHz.

During standby mode, the IDT71V3557SA85BGG consumes low power, making it suitable for battery-powered devices. When not in use, it automatically enters a power-down state to further reduce power consumption. The memory also features built-in self-refresh capability, ensuring data retention even during power-off periods.

The IDT71V3557SA85BGG supports both byte-write and word-write operations, providing flexibility in data manipulation. It also includes on-chip address and control registers, simplifying the interfacing process with external systems.
