7206L35J8

Overview

The Renesas Electronics 7206L35J8 is a 16K x 9 asynchronous FIFO memory device housed in a 32-pin PLCC package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an access time of 35 ns. The component features unidirectional data flow, status flags for overflow/underflow prevention, and retransmit capability. Designed for multiprocessing and rate buffering, it allows simultaneous asynchronous read and write operations while maintaining low power consumption.

Feature Summary

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

Applications

• Multiprocessing systems requiring high-speed data transfer
• Rate buffer applications between mismatched data rates
• Asynchronous interface bridging in digital signal processing

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential obsolescence. Confirm RoHS compliance status as historical records indicate non-compliance for this specific part number. Check moisture sensitivity levels and storage conditions prior to installation. Ensure pin compatibility with existing PCB layouts designed for the 7206 family. Validate lead-free status if required by current environmental regulations.

Selection Notes

Select this component when a 16K x 9 depth and 9-bit width are required for asynchronous FIFO operations. Choose based on the 35 ns access speed suitable for moderate-frequency clocking. Consider the PLCC-32 package for surface-mount assembly needs. Evaluate the 5V TTL-compatible I/O requirements against system logic levels. Assess the need for retransmit functionality before finalizing the design choice.

Part Context

This device belongs to the 7206L series of asynchronous FIFOs manufactured by Renesas Electronics. It shares functional compatibility with the broader 720X family, offering similar pinouts and operational characteristics. The series is designed for high-speed data buffering in complex electronic systems. Variants within the family differ primarily in access speeds and packaging options.

Replacement Considerations

IDT7206L35J8 is a confirmed substitute part number for this component.
