72V201L10PFGI8

FIFOs Memory Overview

The 72V201L10PFGI8 is a synchronous First-In, First-Out (FIFO) memory device manufactured by Renesas Electronics Corporation. It features a storage organization of 256 words by 9 bits, providing a total capacity of 2.3 kilobits. The component operates with a maximum clock frequency of 100 MHz and supports unidirectional data transfer. It is designed for 5.0 V logic systems and utilizes a 32-pin PLCC package. The device includes clocked read and write controls to manage data buffering efficiently in high-speed digital applications.

FIFOs Memory Feature Summary

• Synchronous FIFO architecture with independent read and write clock domains
• Unidirectional data bus interface for dedicated input/output flow
• Integrated status flags indicating empty, full, and half-full conditions
• Functionally compatible with legacy 5V FIFO standards

FIFOs Memory Applications

• Data buffering in graphics processing systems
• Interprocessor communication links
• Local area network interface buffering
• Protocol conversion between asynchronous and synchronous domains

FIFOs Memory Procurement Notes

Verify the specific suffix 'I8' against official Renesas documentation to confirm package variant and lead-free status, as standard listings may vary. Confirm end-of-life status via recent Product Change Notifications. Ensure design-in compatibility with 5V logic levels if replacing older components. Check moisture sensitivity level requirements for surface mount assembly processes.

FIFOs Memory Selection Notes

Select this component when a 5V synchronous FIFO with 9-bit width and 256-word depth is required. It is suitable for applications needing simple, low-latency data buffering without complex configuration. Consider the PLCC package availability if redesigning existing through-hole or specific surface-mount layouts. Verify that the 100 MHz speed meets system timing constraints.

FIFOs Memory Part Context

This part belongs to the IDT/72V2xx1 family of synchronous FIFOs, originally developed by Integrated Device Technology and now produced by Renesas. These devices are widely used in telecommunications and networking equipment for temporary data storage. The 72V201 specifically targets 5V applications, distinguishing it from the 3.3V 72V201L variants.

FIFOs Memory Replacement Considerations

Official substitutes include the 72V201L10PFGI8 for 3.3V operation, though voltage differences must be addressed. Legacy equivalents such as the 72201 may be functionally similar but differ in power specifications. Verify pinout compatibility before substitution.
