7206L15J

Overview

The Renesas Electronics Corporation 7206L15J is an asynchronous FIFO memory device with a storage capacity of 144 kbit, organized as 16K x 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports unidirectional data transfer. The component features a maximum clock frequency of 40 MHz and an access time of 15 ns. It is designed for applications requiring simultaneous asynchronous read and write operations. The device includes status flags such as Empty, Half-Full, and Full to manage data flow effectively.

Feature Summary

• Supports asynchronous and simultaneous read/write operations for multiprocessing environments
• Includes Auto-retransmit capability allowing reset of the read pointer to its initial position
• Utilizes Full and Empty flags to prevent data overflow and underflow conditions

Applications

• Multiprocessing systems requiring high-speed data buffering
• Rate buffer applications between components operating at different speeds
• Asynchronous data transfer interfaces in digital logic circuits

Procurement Notes

Verify the exact suffix designation (e.g., JG, TP) as the base model number may refer to multiple package variants. Confirm RoHS compliance status and moisture sensitivity level requirements for your specific assembly process. Check current production status as this series may be subject to discontinuation notices. Ensure compatibility with existing system voltage levels and timing constraints before procurement.

Selection Notes

Select this component when a 16K x 9 asynchronous FIFO is required with 15 ns access speed. Consider the PLCC-32 or PDIP-28 package based on board layout constraints. Verify that the 4.5 V to 5.5 V operating range matches the system power supply. Evaluate if the unidirectional bus direction meets the data flow requirements of the target application design.
