7203L15J8

Overview

The Renesas Electronics Corporation 7203L15J8 is an asynchronous FIFO memory integrated circuit featuring a storage capacity of 18K bits, organized as 2K words by 9 bits. It operates with a maximum data rate of 40MHz and an access time of 15ns. The device supports unidirectional bus direction and functions within a supply voltage range of 4.5V to 5.5V, drawing a maximum supply current of 120mA. It is housed in a 32-PLCC package with dimensions of 14x11.46mm and is rated for an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Supports asynchronous read and write operations for simultaneous data handling
• Includes retransmit capability to reset the read pointer to its initial position
• Utilizes status flags such as Empty, Half-Full, and Full to prevent overflow and underflow

Applications

• Multiprocessing systems requiring data buffering
• Rate matching applications between different clock domains
• Data acquisition systems needing temporary storage

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package integrity and moisture sensitivity level handling procedures before assembly. Ensure replacement strategies are documented given the discontinuation notice.

Selection Notes

Select this component when a 2K x 9 asynchronous FIFO with 15ns access time is required. Consider the 32-PLCC package constraint and 4.5V to 5.5V supply voltage range. Evaluate thermal management needs for the -40°C to +85°C industrial temperature range. Compare against newer families if long-term availability is critical.

Part Context

The 7203L15J8 belongs to the Renesas 7200 series of high-speed asynchronous FIFOs. This family is designed for multiprocessing and rate buffer applications. The device provides reliable data storage with full and empty flags. It is pin and functionally compatible with other members of the 720X family, facilitating design upgrades or replacements within existing architectures.

Replacement Considerations

Check for functional equivalents in the 7200 series with similar timing and organization. Verify pin compatibility for direct socket replacement. Assess electrical parameter alignment for voltage and current specifications.
