7203L15PDG

Overview

The Renesas Electronics Corporation 7203L15PDG is an asynchronous FIFO memory device with a storage capacity of 18K bits, organized as 2K words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 15 ns. The component supports unidirectional data transfer at speeds up to 40 MHz. It is housed in a 28-pin PDIP package and is rated for an operating temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous operation for independent read and write clock domains
• Uni-directional bus architecture for dedicated data buffering
• CMOS technology ensuring low power consumption

Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging between systems with different clock speeds
• Temporary data storage in high-speed digital signal processing chains

Procurement Notes

Verify the specific suffix PDG confirms the 28-pin PDIP package and commercial temperature grade. Confirm RoHS compliance status as historical data indicates potential non-compliance for older batches. Check for End-of-Life notices or obsolescence warnings from Renesas before finalizing procurement plans.

Selection Notes

Select this component when a uni-directional asynchronous buffer is required with a 9-bit word width. Ensure the application environment stays within the 0°C to 70°C operating range. Verify that the 28-pin PDIP footprint matches the PCB design constraints compared to PLCC alternatives.

Part Context

This part belongs to the Renesas 7203 series of asynchronous FIFOs. It shares architectural similarities with other members like the 7203L15JI but differs in packaging and thermal rating. The series provides reliable data buffering solutions for legacy and industrial embedded systems requiring simple interface management.

Replacement Considerations

Direct substitutes include IDT7203L15PDG. Cross-reference pinouts and electrical characteristics carefully when considering alternative manufacturers.
