7205L12JG

Overview

The Renesas Electronics Corporation 7205L12JG is an asynchronous FIFO memory device belonging to the 7205L series. It provides a storage capacity of 8K words by 9 bits, totaling 72 kilobits. The component operates with a maximum access time of 12 nanoseconds and supports data rates up to 15 MHz. It functions as a unidirectional buffer and includes relay capability. The device is designed for operation within a supply voltage range of 4.5 V to 5.5 V and is housed in a PLCC-32 package.

Feature Summary

• Asynchronous operation allowing independent read and write clock domains
• Unidirectional data flow architecture
• Integrated relay capability for signal buffering

Applications

• Data buffering between asynchronous logic systems
• Interface bridging in high-speed digital circuits
• Temporary data storage in communication protocols

Procurement Notes

Verify the specific suffix JG corresponds to the PLCC-32 plastic leaded chip carrier package configuration. Confirm RoHS compliance status as older variants may not meet current environmental standards. Check for active manufacturing status or obsolescence notices from Renesas Electronics before finalizing procurement plans.

Selection Notes

Select this component when an 8K x 9 word depth is required for unidirectional data transfer. Ensure the system design accommodates the 12 ns access time and 15 MHz operational frequency limits. Verify that the PLCC-32 surface mount package aligns with the PCB layout constraints and thermal requirements of the target application.
