7206L15J8

Overview

The Renesas Electronics Corporation 7206L15J8 is an asynchronous FIFO memory device with a storage capacity of 144 kbit, organized as 16K x 9. It features a unidirectional bus and operates within a supply voltage range of 4.5 V to 5.5 V. The component supports a maximum clock frequency of 40 MHz with an access time of 15 ns. It is housed in a PLCC-32 package and functions as a single circuit. The device is designed for applications requiring simultaneous read and write operations.

Feature Summary

• Supports asynchronous and simultaneous read/write operations for multiprocessing environments
• Includes Full and Empty status flags to prevent data overflow and underflow
• Features auto-retransmit capability allowing reset of the read pointer when triggered

Applications

• Multiprocessing systems requiring high-speed data buffering
• Rate buffer applications between asynchronous domains
• Data acquisition systems needing first-in/first-out memory management

Procurement Notes

Verify current availability status as this component may be discontinued or subject to limited stock. Confirm RoHS compliance details and moisture sensitivity level before procurement. Check for official Product Change Notices regarding manufacturing origin or packaging updates. Ensure compatibility with existing system voltage requirements of 4.5 V to 5.5 V. Validate pinout alignment if replacing older variants within the same family.

Selection Notes

Select this part for designs requiring a 16K x 9 asynchronous FIFO interface. Ensure the application supports unidirectional data flow and requires 15 ns access speed. Verify that the PLCC-32 surface mount package fits the board layout constraints. Confirm that the operating temperature range of 0°C to +70°C meets environmental specifications. Consider power consumption limits relative to the 120 mA maximum supply current.

Part Context

This component belongs to the 7206L series of dual-port FIFO memories manufactured by Renesas Electronics. It is functionally compatible with the broader 720X family of devices. The part serves as a specialized memory solution for managing data streams in digital logic circuits. It shares architectural similarities with other asynchronous FIFOs but offers specific depth and width configurations.

Replacement Considerations

IDT7206L15JG8 is a verified substitute part number for this component.
