5962-8956804XA

Overview

The Renesas Electronics Corporation 5962-8956804XA is an asynchronous FIFO memory device with a capacity of 4K x 9 bits. It operates at a maximum clock frequency of 15 MHz and features a 50 ns access time. The component utilizes a 28-pin CDIP package and supports unidirectional data transfer. It functions as a dual-port FIFO memory that loads and empties data on a first-in/first-out basis, incorporating Full and Empty status flags for flow control.

Feature Summary

• Asynchronous FIFO architecture supporting unidirectional data transfer
• Dual-port memory structure with integrated Full and Empty status flags
• First-in/first-out data loading and emptying mechanism

Applications

• Data buffering in high-speed digital systems
• Interface bridging between components with different clock domains
• Temporary storage in parallel communication interfaces

Procurement Notes

This component is classified as obsolete or discontinued by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or qualified replacement sources. Ensure compatibility with existing system designs before procurement due to end-of-life status.

Selection Notes

Select this part for applications requiring simple asynchronous FIFO buffering with 9-bit word width. Verify that the 28-pin CDIP package fits the target PCB layout. Confirm that the 50 ns speed and 15 MHz frequency meet system timing requirements. Consider pinout compatibility if replacing older IDT 7204 equivalents.

Part Context

The 5962-8956804XA belongs to the 5962-89568 series of dual-port FIFO memories. This series includes variants such as the 5962-8956806XA and 5962-8956807XA, which share similar architectural features but may differ in speed grades or specific flag configurations. These parts are legacy CMOS devices designed for robust parallel data handling.

Replacement Considerations

Public confirmed substitute part numbers include IDT 7204 equivalents within the same family. Verify functional equivalence regarding pinout, voltage levels, and timing parameters when sourcing replacements from other manufacturers.
