Additional Details

The IDT70V659S12BF Dual-Port SRAM operates from a single 3.3V power supply. It features independent control signals for each port, allowing asynchronous read and write operations. The device includes on-chip arbitration logic to prevent data corruption when both ports attempt to access the same memory location simultaneously. This device is particularly well-suited for applications where minimizing latency and maximizing data throughput are critical.

Specific technical specifications include a typical operating current of around 200mA, and a standby current of less than 50mA. The operating temperature range is typically between 0°C and 70°C. Refer to the IDT datasheet for detailed timing diagrams, voltage levels, and other critical parameters.
