The 70V7319S133BC is a high-speed 256K x 18 synchronous bank-switchable dual-port static RAM from Quarktwin Technology Ltd. It features a maximum access time of 4.2 ns at 133 MHz, making it suitable for applications requiring fast data access. The device is organized into 64 independent 4K x 18 banks, allowing simultaneous access from both ports, which can operate independently with separate control, address, and I/O pins. This SRAM supports a selectable power supply of either 3.3V or 2.5V for I/O and control signals, while the core operates at 3.3V. It is designed for industrial temperature ranges from -40¬8C to +85¬8C and is available in a 256-pin CABGA package. The product also includes features such as self-timed write capabilities, automatic power-down modes, and compliance with JTAG standards. The dual chip enables facilitate depth expansion without additional logic, making it a versatile choice for various applications.
