7200L20J8

Overview

The Renesas Electronics Corporation 7200L20J8 is an asynchronous FIFO memory integrated circuit with a storage capacity of 2.25K bits, organized as 256 words by 9 bits. It features a 20 nanosecond access time and supports a data rate of 33.3 MHz. The device operates on a single power supply voltage ranging from 4.5 V to 5.5 V, with a maximum supply current of 80 mA. It utilizes a unidirectional bus interface and is housed in a 32-pin PLCC package.

Feature Summary

• Asynchronous operation enabling simultaneous independent read and write cycles
• Uni-directional bus architecture for dedicated data flow control
• Retransmit capability allowing read pointer reset to initial position

Applications

• Multiprocessing systems requiring data buffering
• Rate matching between components operating at different speeds
• Data acquisition systems needing temporary storage

Procurement Notes

Verify component authenticity through authorized distributors or official Renesas channels due to end-of-life status. Confirm RoHS compliance requirements against specific project standards, as this variant may not meet current environmental directives. Validate package integrity upon receipt to ensure suitability for surface-mount assembly processes.

Selection Notes

Select this component when a 256x9 word depth asynchronous FIFO is required with 20 ns timing constraints. Ensure the design accommodates the 32-PLCC package dimensions and 4.5V to 5.5V supply range. Consider the unidirectional nature of the bus if bidirectional data transfer is needed, which would require alternative solutions.

Part Context

This part belongs to the 7200 series of high-speed CMOS FIFOs manufactured by Renesas Electronics. The series is characterized by low power consumption and high-speed performance suitable for complex digital logic applications. The 7200L20J8 specifically denotes the 20 ns speed grade within the L20 family variants.
