7208L20JG

Overview

The Renesas Electronics Corporation 7208L20JG is an asynchronous FIFO memory IC with a storage capacity of 576K bits, organized as 64K words by 9 bits. It features a parallel interface and supports unidirectional data bus direction. The device operates within a supply voltage range of 4.5V to 5.5V and offers an access time of 20ns with a data rate of 33.3MHz. It is housed in a 32-PLCC surface-mount package measuring 14mm by 11.46mm. The component supports retransmit capability but lacks programmable flag support or First Word Fall Through (FWFT).

Feature Summary

• Supports asynchronous and simultaneous read/write operations for multiprocessing applications.
• Includes retransmit capability allowing reset of the read pointer to its initial position.
• Fully expandable by both word depth and bit width.

Applications

• Multiprocessing systems requiring high-speed data buffering.
• Rate buffer applications between components operating at different speeds.
• Data acquisition systems needing temporary storage before processing.

Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm RoHS compliance requirements against specific project standards, noting that some variants may not meet current regulations. Validate package dimensions and pinout compatibility during integration planning. Check for available replacement options from the manufacturer's updated portfolio.

Selection Notes

Select this component when designing systems requiring reliable asynchronous FIFO buffering with 9-bit data width. Ensure the design accommodates the 32-PLCC package constraints and 4.5V to 5.5V power supply requirements. Consider the 20ns access time for timing analysis in high-speed digital circuits. Evaluate alternative packages if surface-mount space is limited.

Part Context

This part belongs to the 7200 series of asynchronous FIFO memories manufactured by Renesas Electronics. The series is designed for applications requiring first-in/first-out data handling with full expandability. The 7208 variant specifically provides 64K x 9 organization, distinguishing it from other densities in the family such as the 7207 or 7202 models.

Replacement Considerations

Public confirmed substitute part numbers include IDT7208L20J8 and 7208L20J8. These parts share identical electrical specifications and pinouts. Verify package availability and RoHS compliance status for the specific suffix variant required.
