7203L35J8

Overview

The Renesas Electronics Corporation 7203L35J8 is an asynchronous FIFO memory integrated circuit featuring a storage capacity of 18K bits, organized as 2K words by 9 bits. It operates with a maximum data rate of 22.22 MHz and an access time of 35 ns. The device supports unidirectional bus architecture and functions within a supply voltage range of 4.5 V to 5.5 V. It is housed in a 32-pin PLCC package.

Feature Summary

• Asynchronous read and write operations for independent clock domains
• Retransmit capability allows resetting the read pointer to its initial position
• Status flags including Empty, Half-Full, and Full prevent data overflow and underflow

Applications

• Multiprocessing systems requiring data buffering
• Rate buffer applications between different speed components
• Data acquisition systems needing temporary storage

Procurement Notes

Verify component authenticity due to discontinued status. Confirm lead-free compliance requirements against RoHS standards. Check moisture sensitivity level handling procedures during assembly. Validate pin compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component for designs requiring 2Kx9 asynchronous buffering. Ensure system clocks align with the 35 ns access time limit. Verify power supply stability within the specified voltage range. Consider package availability constraints given end-of-life status.

Part Context

Part of the 7203 series asynchronous FIFO family. Designed for high-speed data transfer between asynchronous logic blocks. Provides reliable first-in-first-out memory management with hardware-controlled status flags.

Replacement Considerations

IDT7203L35J8 is a confirmed substitute part number.
