72V3642L15PFGI8

FIFOs Memory Overview

The 72V3642L15PFGI8 is a dual synchronous FIFO memory device manufactured by Renesas Electronics. It features two independent 1K x 36 dual-port SRAM FIFOs, providing a total storage capacity of 72 kbit. The component supports clock frequencies up to 100 MHz with an access time of 10 ns. It operates within a supply voltage range of 3 V to 3.6 V and includes programmable Almost-Full and Almost-Empty flags. The device is housed in a 120-pin TQFP package.

FIFOs Memory Feature Summary

• Dual independent clocked FIFOs buffer data in opposite directions
• Supports bidirectional interface between microprocessors and buses
• Programmable Almost-Full and Almost-Empty status flags

FIFOs Memory Applications

• Interprocessor communication buffering
• Data rate matching between asynchronous systems
• Network controller data handling

FIFOs Memory Procurement Notes

Verify the specific suffix 'I8' against official documentation, as standard listings for this series typically use 'PF' or 'PFG'. Confirm current lifecycle status, as many variants in the 72V3642 family are marked obsolete. Ensure compatibility with existing board designs regarding moisture sensitivity levels and lead-free requirements before procurement.

FIFOs Memory Selection Notes

Select this component when dual independent FIFO buffers are required for high-speed data transfer. The 100 MHz maximum clock frequency and 10 ns access time suit demanding synchronization tasks. Verify that the 120-pin TQFP package fits the available PCB footprint and that the 3.3V logic level matches the system voltage.

FIFOs Memory Part Context

This part belongs to the 72V3642 series of dual synchronous FIFOs. It shares architectural similarities with other members like the 72V3642L10PFG but offers different timing characteristics. The series is designed for applications requiring efficient data buffering between components operating at different speeds or clock domains.

FIFOs Memory Replacement Considerations

Check for direct substitutes such as the 72V3642L10PFG or 72V3642L15PFG. Verify pinout compatibility and electrical specifications. Note that some variants may be obsolete; confirm availability and lifecycle status with the manufacturer.
