7205L35J8

Overview

The Renesas Electronics Corporation 7205L35J8 is an asynchronous FIFO memory device with a capacity of 72K bits, organized as 8K words by 9 bits. It features a maximum access time of 35 ns and supports a clock frequency up to 22.2 MHz. The component operates within a supply voltage range of 4.5 V to 5.5 V and includes retransmit functionality. It is housed in a 32-pin PLCC package.

Feature Summary

• Supports asynchronous read and write operations for data buffering
• Includes retransmit capability for pointer reset control
• Provides status flags to manage data flow

Applications

• Multiprocessing systems requiring data synchronization
• Rate buffer applications between different speed domains
• Asynchronous interface bridging in digital circuits

Procurement Notes

Verify the current lifecycle status before procurement, as this component may be discontinued or subject to limited availability. Confirm that the lead-free and RoHS compliance requirements align with project specifications, noting potential non-compliance with modern environmental standards. Ensure the 32-PLCC package footprint matches the target PCB design constraints.

Selection Notes

Select this component when a 9-bit wide asynchronous FIFO is required for rate matching or data buffering. Consider the 35 ns access time and 22.2 MHz maximum frequency against system timing requirements. Verify compatibility with 5V logic levels and ensure the PLCC package style fits the assembly process capabilities.

Part Context

This part belongs to the 7205 series of CMOS FIFO memories manufactured by Renesas Electronics. The series typically offers various access speeds and organization options. The 7205L35J8 specifically denotes the 35 ns speed grade within this family, utilizing standard parallel interfaces for data transfer.

Replacement Considerations

Check for direct pin-compatible substitutes within the same 7205 series family, such as variants with different access times like the 7205L25J8. Verify functional equivalence regarding word width and depth before substitution.
