7206L20J8

Overview

The Renesas Electronics Corporation 7206L20J8 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 for pointer reset functions. It is housed in a 32-pin PLCC package and is designed for multiprocessing and rate buffering applications requiring simultaneous asynchronous read and write operations.

Feature Summary

• Supports asynchronous and simultaneous read/write operations for efficient data handling
• Includes retransmit (RT) capability allowing read pointer reset to initial position
• Utilizes Full and Empty status flags to prevent data overflow and underflow conditions

Applications

• Multiprocessing systems requiring high-speed data transfer
• Rate buffer applications between mismatched clock domains
• Data acquisition systems needing temporary storage buffers

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance requirements against project specifications as the part may not meet current environmental standards. Validate pin compatibility with existing PCB layouts before procurement. Ensure proper handling procedures are followed during installation to maintain signal integrity.

Selection Notes

Evaluate system timing constraints against the 20 ns access time specification. Consider power consumption limits relative to the 120 mA maximum supply current. Assess physical space availability for the 32-PLCC package dimensions. Verify interface compatibility with target logic families operating at 5.0 V TTL levels. Review thermal management requirements for the intended operating temperature range.

Part Context

This component belongs to the 7206 series of asynchronous FIFO memories manufactured by Renesas Electronics. The series provides dual-port memory functionality optimized for high-speed data buffering tasks. The 7206L20J8 variant specifically offers 16K x 9 organization in a surface-mount package. It represents a legacy product line designed for robust industrial and commercial applications requiring reliable first-in-first-out data storage capabilities.

Replacement Considerations

The 7206L15JG is listed as an upgrade substitute by the manufacturer. Verify functional equivalence regarding pinout and electrical characteristics before implementation.
