7200L50J

Overview

The Renesas Electronics Corporation 7200L50J is an asynchronous FIFO memory device with a storage capacity of 16K x 9 bits. It operates on a single 5.0V supply voltage, accepting inputs within the 4.5 V to 5.5 V range. The component features a maximum access time of 50 ns and supports a data rate up to 20 MHz. It utilizes a unidirectional bus architecture and is housed in a 32-PLCC package. Designed for multiprocessing and rate buffering applications, it employs Full and Empty flags to manage data flow.

Feature Summary

• Supports asynchronous read and write operations for simultaneous data handling
• Includes Retransmit (RT) capability to reset the read pointer to its initial position
• Utilizes Full and Empty status flags to prevent data overflow and underflow

Applications

• Multiprocessing systems requiring independent clock domains
• Rate buffer applications between mismatched speed components
• Data acquisition systems needing temporary storage

Procurement Notes

Verify RoHS compliance status as older variants may not meet current environmental standards. Confirm moisture sensitivity level requirements for surface mount assembly processes. Check for specific EOL notices or last-time buy deadlines from the manufacturer. Ensure pin compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component when a 16K depth and 9-bit width are required for asynchronous buffering. Consider the 50 ns access time against system timing constraints. Evaluate the PLCC package suitability for the target application environment. Compare performance metrics with newer series if long-term availability is critical.

Part Context

This part belongs to the IDT 7200 series of dual-port FIFO memories. It is designed for high-speed data transfer between different clock domains. The series is widely used in telecommunications and industrial control systems. Renesas Electronics continues to support legacy parts through official documentation channels.

Replacement Considerations

Official substitutes include the 7200L25J and 7200L12JG. Verify pinout compatibility and electrical specifications before substitution.
