7207L20J

Overview

The Renesas Electronics Corporation 7207L20J is an asynchronous FIFO memory device with a storage capacity of 288K bits, organized as 32K words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 20 ns. The component utilizes a 32-pin PLCC package and supports unidirectional data bus direction. Designed for multiprocessing and rate buffering applications, it employs Full and Empty status flags to manage data overflow and underflow conditions effectively.

Feature Summary

• Supports asynchronous and simultaneous read/write operations for efficient data handling in multiprocessing environments
• Includes retransmit capability allowing the read pointer to reset to its initial position upon low pulse activation
• Utilizes Full and Empty status flags to prevent data overflow and underflow during operation

Applications

• Multiprocessing systems requiring high-speed data transfer
• Rate buffer applications between components operating at different clock speeds
• Asynchronous communication interfaces needing reliable first-in/first-out memory management

Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check moisture sensitivity level specifications before soldering to ensure proper handling procedures are followed during assembly processes.

Selection Notes

Consider the 7207L20J for designs requiring 32K x 9 organization with 20 ns access speed. Evaluate compatibility with existing 5V logic levels and PLCC footprint constraints. Assess whether unidirectional data flow meets system architecture needs compared to bidirectional alternatives.

Part Context

Part of the 7207L series offering CMOS parallel FIFO solutions. Provides expandable depth and width capabilities while maintaining low power consumption characteristics. Compatible with MIL-STD-883 Class B standards for ruggedized applications when specified.

Replacement Considerations

IDT7207L20J serves as a direct functional substitute from Integrated Device Technology. Verify pinout compatibility and electrical parameter alignment before implementation.
