7205L35TP

Overview

The Renesas Electronics Corporation 7205L35TP is an asynchronous FIFO memory device organized as 8K x 9 bits, providing a total storage capacity of 72 kilobits. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum access time of 35 ns with a clock frequency of 22.2 MHz. The component utilizes a 28-pin PDIP package for through-hole mounting. It supports unidirectional data transfer and includes retransmit capability for pointer reset functions.

Feature Summary

• Supports asynchronous read and write operations for independent clock domains
• Includes retransmit capability allowing read pointer reset upon signal pulse
• Utilizes Full and Empty status flags to manage data overflow and underflow conditions

Applications

• Multiprocessing systems requiring data buffering between processors
• Rate matching applications involving asynchronous data streams
• Digital signal processing interfaces requiring temporary data storage

Procurement Notes

Verify component authenticity due to obsolete status. Confirm RoHS compliance requirements as the part is marked non-compliant. Check for lead-free alternatives if environmental regulations apply. Validate package integrity for the 28-pin DIP configuration. Ensure compatibility with existing system voltage levels before integration.

Selection Notes

Select this component when 8K x 9 depth and 35 ns speed are required. Consider the 28-pin PDIP package for prototyping or low-volume assembly. Evaluate power consumption against system constraints given the 120 mA maximum supply current. Verify that unidirectional data flow meets application needs without bidirectional requirements.

Part Context

This device belongs to the 7205 series of high-speed CMOS FIFO memories manufactured by Renesas Electronics. The series offers various speed grades and organization options. The 7205L35TP specifically targets applications needing moderate speed and standard parallel interface connectivity within industrial or commercial temperature ranges.

Replacement Considerations

IDT7205L35TP serves as a direct functional substitute from Integrated Device Technology. Cross-reference pinouts and electrical specifications to ensure compatibility. Verify package dimensions match the existing PCB footprint. Confirm logic level compatibility with downstream components.
