7207L25J

Overview

The 7207L25J is an asynchronous FIFO memory component manufactured by Renesas Electronics. It features a storage organization of 32K x 9 bits, providing a total capacity of 288 Kbits. The device operates with a maximum clock frequency of 22.22 MHz and supports a data rate of 22.22 MHz. It has a specified access time of 35 ns. The unit functions within a supply voltage range of 4.5 V to 5.5 V. It utilizes a unidirectional bus direction and is housed in a 32-PLCC package.

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 data buffering
• Rate buffer applications between asynchronous domains
• Data transfer interfaces requiring first-in/first-out sequencing

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check moisture sensitivity level handling procedures before assembly. Validate pin compatibility with existing PCB layouts using official datasheets. Ensure substitute parts are functionally equivalent if original stock is unavailable.

Selection Notes

Select this component when a 32K x 9 asynchronous FIFO with 35 ns access time is required. Ensure system voltage matches the 4.5 V to 5.5 V operating range. Verify that unidirectional data flow meets application needs. Consider package constraints for 32-PLCC footprint availability. Evaluate thermal performance within the specified industrial temperature range.

Part Context
