7205L35J

Overview

The Renesas Electronics Corporation 7205L35J is an asynchronous FIFO memory device organized as 8K x 9, providing a total storage capacity of 72 kilobits. It operates with a maximum access time of 35 nanoseconds and supports data rates up to 22.2 MHz. The component functions within a supply voltage range of 4.5 V to 5.5 V and draws a maximum supply current of 120 mA. Designed for unidirectional bus applications, it utilizes a 32-pin PLCC package with J-leads, measuring 14 mm by 11.46 mm. The device supports surface mount installation and operates reliably across a commercial temperature range of 0°C to 70°C.

Feature Summary

• Supports asynchronous read and write operations for simultaneous data handling in multiprocessing environments.
• Includes auto-retransmit capability allowing the read pointer to reset to its initial position upon specific control signals.
• Utilizes Full and Empty status flags to prevent data overflow and underflow conditions during operation.

Applications

• Multiprocessing systems requiring high-speed data buffering between independent clock domains.
• Rate buffer applications managing data flow discrepancies between source and destination devices.
• Parallel interface communication links requiring reliable first-in-first-out data sequencing.

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate pin compatibility with existing PCB layouts before integration. Check for available legacy stock or qualified replacement alternatives from official distributors.

Selection Notes

Select this component for applications requiring 8K x 9 word depth with 35 ns access speed. Ensure system power supplies maintain the 4.5 V to 5.5 V operating range. Verify that the 32-PLCC package fits the designated footprint. Consider thermal management for the 120 mA maximum current draw in enclosed designs.

Part Context

This device belongs to the IDT 7205 family of asynchronous FIFO memories manufactured by Renesas Electronics. The family offers various speed grades and configurations for parallel data buffering. The 7205 series is designed for robust performance in industrial and commercial electronic systems requiring reliable temporary data storage.

Replacement Considerations

Consult official documentation for direct pin-compatible substitutes within the same product family. Verify electrical specifications match the original design requirements when selecting alternative components.
