The 7140SA55PF8 is a high-speed 1K x 8 Dual-Port Static SRAM from Quarktwin Technology Ltd. It operates with a maximum access time of 55 ns and is designed for asynchronous memory access, allowing independent read and write operations from two ports. This memory device is compatible with a single 5V ±10% power supply and features low-power operation, consuming approximately 550mW during active use and 5mW in standby mode. The 7140SA55PF8 is available in various package types, including 64-pin TQFP, making it suitable for a range of applications. It is compliant with military specifications (MIL-PRF-38535 QML), ensuring reliability in demanding environments. Additionally, the device supports battery backup operation with 2V data retention capability, enhancing its utility in applications requiring data preservation during power loss. The product is ideal for systems that require dual-port memory architecture, enabling efficient data handling without the need for additional logic components.
