7208L35J8

Overview

The Renesas Electronics Corporation 7208L35J8 is an asynchronous FIFO memory integrated circuit manufactured by Renesas. It features a storage capacity of 576K bits, organized as 64K words by 9 bits. The device supports unidirectional data transfer with a maximum clock frequency of 22.22MHz and an access time of 35ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 120mA. The component is housed in a 32-PLCC package with J-leads, measuring 14x11.46mm. It functions within an industrial temperature range of 0°C to 70°C.

Feature Summary

• Supports asynchronous and simultaneous read/write operations for multiprocessing applications
• Includes retransmit capability allowing reset of the read pointer to its initial position
• Utilizes Full and Empty status flags to prevent data overflow and underflow

Applications

• Multiprocessing systems requiring rate buffering
• Data acquisition systems needing temporary storage
• Digital signal processing interfaces

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the part is non-compliant. Check moisture sensitivity level (MSL 3) handling procedures during assembly. Validate pin compatibility with existing designs referencing the 720X family. Ensure supply chain stability given discontinued manufacturing status.

Selection Notes

Select this component for applications requiring high-density asynchronous FIFO buffering with 9-bit word width. Consider the 35ns access speed suitable for moderate-frequency digital interfaces. Evaluate the 32-PLCC package constraints against PCB layout requirements. Assess power consumption limits against system thermal design capabilities.

Part Context

The 7208L35J8 belongs to the Renesas 7200 series of CMOS parallel FIFO memories. This series provides expandable depth and bit width options for various memory buffering needs. The component represents a legacy solution from Integrated Device Technology before Renesas acquisition.

Replacement Considerations

Public confirmed substitute part numbers include IDT7208L35J8.
