723641L20PFG

FIFOs Memory Overview

The Renesas Electronics Corporation 723641L20PFG is a synchronous FIFO memory device belonging to the 72V series. It features a storage capacity of 72K organized as 2K x 36 bits, with an additional 2K x 36-bit buffer for bidirectional data transfer. The component supports a maximum clock frequency of 50MHz and offers a typical access time of 20ns. It operates within a supply voltage range of 3V to 3.6V and draws a maximum supply current of 40mA. Designed for surface mount installation, it is housed in a 120-TQFP (14x14) package and functions reliably across an operating temperature range of 0°C to 70°C.

FIFOs Memory Feature Summary

• Supports bidirectional data flow between two independent clocks
• Includes programmable flags for full, empty, and almost full conditions
• Features First Word Fall Through (FWFT) mode for reduced latency

FIFOs Memory Applications

• Data buffering in high-speed digital signal processing systems
• Clock domain crossing interfaces in telecommunications equipment
• Temporary storage in video processing pipelines

FIFOs Memory Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements prior to PCB assembly. Review official product change notices for any recent manufacturing updates or label changes that may affect part identification.

FIFOs Memory Selection Notes

Select this component when a wide 36-bit data path is required for synchronous FIFO operations. Ensure the system design accommodates the 3V to 3.6V supply voltage range and 120-pin TQFP footprint. Consider the 50MHz maximum clock speed and 20ns access time against application timing constraints.

FIFOs Memory Part Context

This part belongs to the Renesas 72V series of high-performance synchronous FIFOs. It shares architectural similarities with other members like the 72V3642 and 72V831 but differs in data width and organization. The series is designed for applications requiring reliable data buffering between asynchronous or synchronous domains.

FIFOs Memory Replacement Considerations

Consult official Renesas documentation for verified substitute part numbers. Cross-reference pinouts and electrical specifications before considering alternatives.
