The CXK5864BP-10LL is a high-speed, low-power 64K (8,192 words x 8 bits) static random-access memory (SRAM) manufactured by Sony. This SRAM is designed for applications requiring fast access times and low power consumption. Being an end-of-life (EOL) product, it is typically found in legacy systems or specialized applications where its specific characteristics are critical.

Applications

• Embedded Systems: Used in embedded systems for fast data storage and retrieval, particularly in applications with real-time constraints.
• Industrial Control Systems: Integrated into industrial control boards where quick data access is critical for efficient operation.
• Communication Equipment: Utilized in communication devices for buffering data and storing configuration parameters.
• Data Acquisition Systems: Employed in data acquisition systems for temporary data storage and processing before transmission.
• Legacy Systems: Found in older systems specifically designed to utilize this SRAM due to its particular specifications and compatibility.

Features

• High-Speed Access Time: Offers a fast access time of 10 ns, allowing for rapid data retrieval.
• Low Power Consumption: Designed for low power operation, making it suitable for battery-powered devices and energy-sensitive applications.
• Fully Static Operation: Requires no clock or refresh cycles, simplifying system design and reducing overhead.
• TTL Compatible Inputs and Outputs: Compatible with standard TTL logic levels, facilitating easy interfacing with other components.
• Single 5V Power Supply: Operates from a single 5V power supply, simplifying power supply requirements.

Benefits

• Fast Data Access: Enables quick and efficient data retrieval, improving system performance and responsiveness.
• Low Power Operation: Reduces power consumption, extending battery life in portable devices and minimizing heat generation.
• Simplified System Design: Fully static operation eliminates the need for external refresh circuitry.
• Easy Integration: TTL compatibility simplifies interfacing with other components in the system.
• Reliable Performance: Provides stable and predictable performance within specified operating conditions.

Additional Details

The CXK5864BP-10LL is typically available in a 28-pin DIP (Dual In-line Package) or SOJ (Small Outline J-lead) package. It operates over a temperature range of 0°C to +70°C. Given its end-of-life status, sourcing this component may require contacting specialized suppliers or distributors that handle legacy components. Verifying the component's availability and condition before incorporating it into a design is important. Also, carefully review datasheets and application notes to ensure it meets the specific requirements of your intended application.
