7206L20J

Overview

The Renesas Electronics Corporation 7206L20J is an asynchronous FIFO memory device with a storage capacity of 144K bits, organized as 16K words by 9 bits. It operates at a data rate of 33.3MHz with a maximum access time of 20ns. The component supports unidirectional bus direction and features retransmit capability. It functions within a supply voltage range of 4.5V to 5.5V, drawing a maximum supply current of 120mA. The device is housed in a 32-PLCC package (14x11.46mm) and is designed for surface mount installation. It supports industrial temperature ranges from 0°C to 70°C.

Feature Summary

• Asynchronous operation enabling simultaneous independent read and write cycles
• Retransmit capability allowing reset of the read pointer to its initial position
• Status flags including Empty, Half-Full, and Full to prevent data overflow and underflow
• Fully expandable architecture supporting both word depth and bit width expansion

Applications

• Multiprocessing systems requiring high-speed data buffering
• Rate buffer applications between components operating at different clock speeds
• Data acquisition systems needing temporary storage before processing

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance requirements against specific project standards, as this variant may not meet current environmental regulations. Validate pin compatibility with existing PCB layouts before procurement. Ensure proper handling procedures are followed during assembly to prevent electrostatic discharge damage to the CMOS circuitry.

Selection Notes

Select this component when asynchronous FIFO functionality with 16K x 9 organization is required. Consider the 20ns access time and 33.3MHz data rate for system timing constraints. Evaluate the 32-PLCC package dimensions against available board space. Compare power consumption specifications with alternative devices if low-power operation is critical. Verify that the unidirectional bus direction meets the system's data flow requirements.
