7204L15J

Overview

The Renesas Electronics Corporation 7204L15J is an asynchronous First-In, First-Out (FIFO) memory device. It features a storage organization of 4K words by 9 bits, providing a total capacity of 36 kilobits. The component supports unidirectional data transfer with a maximum data rate of 40 MHz and a typical access time of 15 nanoseconds. It operates within a supply voltage range of 4.5 V to 5.5 V and draws a maximum supply current of 120 mA. The device is housed in a 32-lead Plastic Leadless Chip Carrier (PLCC) package.

Feature Summary

• Asynchronous FIFO architecture supporting independent read and write clock domains for flexible data buffering.

Applications

• Data buffering in local area network interfaces
• Interprocessor communication systems
• Graphics data buffering applications

Procurement Notes

Verify the specific suffix 'J' against official Renesas documentation to confirm package type and RoHS compliance status. Confirm availability as this part may be discontinued or subject to limited stock constraints. Ensure compatibility with existing system voltage levels and interface requirements before procurement.

Selection Notes

Select this component for applications requiring simple, high-speed asynchronous data buffering between devices operating at different clock rates. The 9-bit width accommodates standard byte-oriented data with parity or error-checking bits. Consider the PLCC package constraints for PCB layout and thermal management during selection.

Part Context

This component belongs to the Renesas 7204 series of asynchronous FIFOs. It serves as a specialized memory solution for temporary data storage in digital logic circuits. The series is designed to handle data flow mismatches between high-speed processors and slower peripherals or buses.
