7201LA12J8

Overview

The 7201LA12J8 is an asynchronous FIFO memory device manufactured by Renesas Electronics. It features a storage organization of 512 words by 9 bits, providing a total capacity of 4.5 Kbits. The component operates with a maximum access time of 12 ns and supports a data rate of 50 MHz. It functions within a supply voltage range of 4.5 V to 5.5 V and draws a maximum supply current of 80 mA. The device utilizes a unidirectional bus interface and is housed in a 32-PLCC package.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• Unidirectional data flow architecture
• CMOS parallel interface technology

Applications

• Data buffering between asynchronous logic systems
• Clock domain crossing applications
• High-speed serial-to-parallel conversion interfaces

Procurement Notes

Verify the specific suffix J8 against official Renesas documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status as historical records vary. Check for End-of-Life notices or obsolescence warnings before procurement planning. Ensure moisture sensitivity level handling procedures are followed during assembly.

Selection Notes

Select this component when a small-capacity, high-speed asynchronous buffer is required. The 12 ns access time suits moderate-speed digital interfaces. Verify that the 9-bit word width matches system requirements without additional bit-padding. Consider the PLCC package constraints for PCB layout and thermal management.

Part Context

This part belongs to the 7201L series of asynchronous FIFOs from Renesas. It is functionally similar to other variants like the 7201LA15J8 but offers faster performance. The series is designed for general-purpose memory buffering in embedded and industrial control systems.

Replacement Considerations

Cross-reference with IDT7201LA12J8 for potential pin-compatible alternatives. Verify electrical specifications match exactly before substitution.
