7207L15J8

Overview

The Renesas Electronics Corporation 7207L15J8 is an asynchronous FIFO memory integrated circuit with a storage capacity of 288K bits, organized as 32K words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum data rate of 66.67 MHz with a 15 ns access time. The device utilizes a 32-pin PLCC package for surface mount installation and functions within an 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 conditions

Applications

• Multiprocessing systems requiring independent clock domains
• Rate buffering between components operating at different speeds
• Data acquisition systems needing temporary storage before processing

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance requirements against specific project standards as this variant may not meet current environmental directives. Validate pin compatibility with existing PCB layouts before integration into new designs.

Selection Notes

Select this component when unidirectional data flow is required without programmable flag customization. Ensure system power supplies remain stable within the 4.5 V to 5.5 V range to maintain timing specifications. Consider thermal management strategies if operating near the upper limit of the specified temperature range.

Part Context

This part belongs to the 7207 series of high-speed asynchronous FIFOs designed for parallel data transfer. It shares functional compatibility with other members of the 720X family while offering specific speed grades and packaging options tailored for industrial and commercial electronic applications requiring reliable buffer memory solutions.

Replacement Considerations

IDT7207L15JG serves as a verified substitute offering identical functionality in tube packaging.
