7202LA50J8

Overview

The Renesas Electronics Corporation 7202LA50J8 is an asynchronous FIFO memory device belonging to the 7202L series. It provides a storage capacity of 9K bits, organized as 1K words by 9 bits. The component supports unidirectional data transfer with a maximum access time of 50ns and a data rate of 15MHz. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 80mA. The device is housed in a 32-PLCC package and functions within an industrial temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous operation enabling simultaneous independent read and write cycles
• Auto-retransmit capability for resetting the read pointer to its initial position
• Status flags indicating empty, half-full, and full conditions to prevent overflow or underflow

Applications

• Multiprocessing systems requiring data buffering
• Rate matching between components operating at different speeds
• Data acquisition systems needing temporary storage

Procurement Notes

Verify the specific suffix J8 against official Renesas documentation to confirm package type and moisture sensitivity level. Confirm RoHS compliance status as historical records indicate variations across the 7202L family. Check for active production status or obsolescence notices prior to procurement. Ensure ESD handling protocols are followed due to CMOS construction.

Selection Notes

Select this component when a 1Kx9 asynchronous FIFO with 50ns access speed is required. Consider the PLCC-32 package constraints for PCB layout. Evaluate if the 15MHz data rate meets system timing requirements. Compare against other 7202L variants if different access times or pinouts are needed.

Part Context

This part belongs to the Renesas 7202L series of high-speed asynchronous FIFOs. The series is designed for applications requiring reliable data buffering in digital systems. The 7202LA50J8 specifically offers a 50ns access time, distinguishing it from faster or slower variants within the same product line.

Replacement Considerations

The IDT7202LA50J8 is listed as an alias for this component. Verify pin compatibility and electrical specifications before substituting with other 7202L family members.
