7206L50J8

Overview

The Renesas Electronics Corporation 7206L50J8 is a 16K x 9 asynchronous FIFO memory device. It features a 9-bit data bus width and operates within a supply voltage range of 4.5 V to 5.5 V. The component provides an access time of 50 ns, supporting a maximum clock frequency of 15 MHz. It utilizes a unidirectional interface architecture and is housed in a 32-pin PLCC package with J-leads.

Feature Summary

• Supports asynchronous and simultaneous read/write operations for multiprocessing applications
• Includes 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 storage interfaces in digital signal processing architectures

Procurement Notes

Verify the specific suffix J8 against current manufacturer documentation to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status as older variants may differ. Check for official End-of-Life notices or discontinuation announcements from Renesas before finalizing procurement plans.

Selection Notes

Select this component when a 16K depth and 9-bit width are required for asynchronous data transfer. Ensure the system design accommodates the 50 ns access time and 15 MHz operational limit. Verify that the 32-pin PLCC package fits the available PCB footprint and assembly constraints.

Part Context

This part belongs to the 7206 family of high-speed asynchronous FIFOs. It shares functional compatibility with the broader 720X series while offering specific timing characteristics defined by the L50 designation. The device is designed for robust data handling in complex electronic systems.

Replacement Considerations

Consult official Renesas substitution guides for verified alternatives. Cross-reference pinouts and electrical specifications carefully if considering generic asynchronous FIFO replacements.
