7204L20J8

Overview

The Renesas Electronics Corporation 7204L20J8 is an asynchronous FIFO memory component with a storage capacity of 32K x 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 device supports unidirectional data transfer at speeds up to 33.3 MHz and includes auto-retransmit capability. It is housed in a 32-PLCC package and functions within the industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports asynchronous and simultaneous read/write operations for multiprocessing applications
• Includes auto-retransmit capability allowing reset of the read pointer to its initial position
• Utilizes Full and Empty status flags to prevent data overflow and underflow

Applications

• Multiprocessing systems requiring rate buffering
• Data acquisition systems needing temporary storage
• Digital signal processing interfaces

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm availability through authorized distributors, noting potential discontinuation or limited stock. Ensure the 32-PLCC package matches your PCB footprint requirements. Validate operating temperature specifications against your environmental constraints before procurement.

Selection Notes

Select this component when a 32K x 9 asynchronous FIFO with 20 ns access time is required. Consider the 32-PLCC package for surface-mount assembly. Verify that the 4.5 V to 5.5 V supply voltage aligns with your system design. Check if the unidirectional bus direction meets your interface needs compared to bidirectional alternatives.

Part Context

This part belongs to the 7204L series of high-speed asynchronous FIFOs from Renesas Electronics. These devices are designed for applications requiring reliable data buffering between different clock domains. The series offers various access times and package options to suit diverse system architectures and performance requirements.

Replacement Considerations

Check for functional equivalents within the 7204L family with compatible pinouts. Verify that substitute parts maintain the same 32K x 9 organization and 20 ns access speed. Ensure replacement components support the required PLCC package and industrial temperature range.
