HSP43216J1-52

Overview

The HSP43216J1-52 is a high-speed static RAM component manufactured by Harris Corporation. It features a 4M-bit (512K x 8) memory organization designed for demanding digital signal processing and high-performance computing applications. The device operates with a 52ns access time, ensuring rapid data retrieval for system-critical tasks. It utilizes a single +5V power supply, simplifying integration into existing logic families. Key electrical characteristics include a typical chip select access time of 52ns and an output enable access time of 40ns. The component supports byte-wide data transfer and includes advanced control signals for efficient memory management in complex electronic architectures.

Feature Summary

• High-speed data access capabilities optimized for real-time processing environments
• Single voltage operation compatible with standard TTL logic levels
• Advanced control logic for precise memory selection and output enabling

Applications

• Digital signal processing systems requiring fast memory throughput
• High-performance computing workstations and servers
• Telecommunications equipment utilizing static RAM buffers

Procurement Notes

Verify the specific suffix J1 against official Harris or subsequent owner datasheets to confirm pinout compatibility and speed grade. Ensure the component meets current environmental compliance standards required for your assembly process. Cross-reference the manufacturer history, as Harris Semiconductor assets were acquired by Intersil and later Renesas, which may affect documentation availability and long-term supply chain verification.

Selection Notes

Select this component when a 512K x 8 configuration with 52ns access time is strictly required. Compare against contemporary SRAMs from Intel or Motorola if alternative sourcing is necessary. Consider power consumption differences between older Harris designs and modern low-power SRAM alternatives. Verify voltage tolerance matches the target system's 5V logic domain without level shifting requirements.

Part Context

This part belongs to the Harris HSP series of high-speed static random-access memories. The series was prominent in the late 1980s and early 1990s for professional audio and video processing. Harris Corporation was a key player in semiconductor solutions before its acquisition by Intersil. The HSP43216 variant represents a dense memory solution for its era, supporting high-bandwidth data paths.

Replacement Considerations

Direct pin-to-pin replacements may be limited due to age. Check Intersil or Renesas catalogs for legacy equivalents. Modern 3.3V SRAMs require level shifters and are not direct substitutes. Verify functional compatibility with any available cross-reference lists from major distributors.
