7203L50TP

Overview

The Renesas Electronics Corporation 7203L50TP is an asynchronous FIFO memory device with a density of 18K bits, organized as 2K x 9. It features a 50ns access time and operates at a maximum data rate of 15MHz. The component supports unidirectional bus architecture and functions within a core voltage range of 4.5V to 5.5V. It utilizes a 28-pin PDIP package and is rated for an operating temperature range of 0°C to 70°C.

Feature Summary

• Provides asynchronous first-in-first-out buffering capabilities for digital signal processing applications.
• Supports uni-directional data transfer architecture with dedicated read and write clock domains.
• Integrates status flags indicating full and empty conditions for flow control management.

Applications

• Data buffering in high-speed serial communication interfaces
• Clock domain crossing synchronization between disparate system frequencies
• Temporary storage in digital signal processing pipelines

Procurement Notes

Verify the specific suffix 'TP' against official Renesas documentation to confirm the 28-pin PDIP package configuration. Confirm that the lead-free status and moisture sensitivity level align with current assembly requirements, as older variants may differ. Ensure compatibility with existing board footprints before finalizing procurement orders.

Selection Notes

Select this component when a 50ns access time and 15MHz operational speed are sufficient for the target application. The 2K x 9 organization suits systems requiring moderate buffer depths with 9-bit data widths. Consider the PDIP package constraints if surface-mount alternatives like PLCC are not feasible for the design.

Part Context

This part belongs to the 7203 series of asynchronous FIFOs manufactured by Renesas Electronics. The series offers various access times and package options to accommodate different performance and form factor requirements in legacy and industrial electronic designs.

Replacement Considerations

Official upgrade substitutes include the 7203L12JG and 7203L12JG8. Verify pinout compatibility and electrical specifications before substituting the discontinued 7203L50TP with these faster alternatives.
