7203L15JI

Overview

The Renesas Electronics Corporation 7203L15JI is an asynchronous FIFO memory device with a storage capacity of 18K bits, organized as 2K x 9. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum data rate of 40 MHz with a 15 ns access time. The component features unidirectional bus architecture and is housed in a 32-PLCC package. It is designed for surface-mount installation and functions across a temperature range of -40°C to 85°C.

Feature Summary

• Asynchronous operation supporting independent read and write clock domains
• Unidirectional data bus architecture for streamlined signal flow
• Integrated status flags indicating full and empty buffer conditions

Applications

• Data buffering between components operating at different clock speeds
• Interface bridging in high-speed digital communication systems
• Temporary data storage in embedded processing architectures

Procurement Notes

Verify the specific suffix requirements against current manufacturer documentation, as the 7203L15JI is listed as discontinued. Confirm RoHS compliance status and moisture sensitivity levels prior to integration. Ensure that any substitute components maintain identical pinout and electrical specifications to avoid redesign efforts. Check for available legacy stock or approved alternates from authorized distributors.

Selection Notes

Select this component when a 2K x 9 asynchronous FIFO with 15 ns speed is required. The 5V logic compatibility suits standard TTL/CMOS interfaces. Consider the PLCC package constraints for PCB layout. Evaluate thermal performance within the specified industrial temperature range. Verify that the unidirectional nature meets system data flow requirements without needing bidirectional support.

Part Context

This part belongs to the Renesas 7203 series of asynchronous FIFOs. It shares architectural similarities with other members like the 7203L12J8 but differs in speed grade and packaging options. The series provides reliable data buffering solutions for legacy and specialized industrial applications requiring deterministic latency and simple interface protocols.
