7206L20LB

Overview

The Renesas Electronics Corporation 7206L20LB is an asynchronous FIFO memory device with a storage capacity of 144K bits, organized as 16K words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum data rate of 33.3 MHz with a 20 ns access time. The component features unidirectional bus architecture and includes retransmit capability. It is housed in a 32-pin LCC package and functions within an industrial temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous operation enabling simultaneous independent read and write cycles
• Retransmit capability allowing reset of the read pointer to its initial position
• Status flags including Empty, Half-Full, and Full to prevent data overflow and underflow
• Expandable depth and width for flexible system integration

Applications

• Multiprocessing systems requiring data buffering
• Rate matching applications between different speed domains
• Data acquisition systems needing temporary storage

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate pin compatibility with existing designs before procurement. Check for available upgrade alternatives such as the 7206L15JG if long-term supply stability is required. Ensure proper handling procedures are followed during installation.

Selection Notes

Select this component for applications requiring high-speed asynchronous data buffering with specific 9-bit word width. Consider the 32-pin LCC package constraints for PCB layout. Evaluate power consumption limits against system thermal design. Assess whether the 20 ns access time meets timing requirements. Verify that the unidirectional bus direction aligns with interface needs.

Part Context

The 7206 series belongs to Renesas' family of high-performance asynchronous FIFO memories. These devices are designed for multiprocessing and rate buffer applications. The 7206L20LB specifically offers 16K x 9 organization. It shares functional compatibility with other members of the 720X family. The series emphasizes low power consumption and ultra-high speed performance.

Replacement Considerations

The 7206L15JG is listed as an upgrade alternative. Verify pinout and electrical parameter compatibility before substitution. Confirm package dimensions match existing footprints. Review datasheet differences for any functional changes.
