The CY7C1359A-150AC is a 256K x 18 synchronous-pipelined cache tag RAM from Quarktwin Technology Ltd. It operates at a clock speed of 150 MHz with a maximum access time of 3.8 ns, making it suitable for high-speed applications. The device features synchronous inputs that are gated by registers controlled by a positive-edge-triggered clock input, allowing for efficient data handling. It supports burst mode operations with control pins for interleaved or linear burst sequences, and includes a pipelined data comparator for fast match times. This memory chip operates from a +3.3V power supply, with output power supply options of +2.5V or +3.3V, and is LVTTL compatible. It has a low-profile 100-pin TQFP package, making it suitable for space-constrained designs. The CY7C1359A-150AC is designed for applications such as address tag RAM in secondary cache systems, and it includes features like automatic power-down for portable applications and individual byte write capabilities.
