72V04L35J8

FIFOs Memory Overview

The Renesas Electronics Corporation 72V04L35J8 is an asynchronous FIFO memory integrated circuit belonging to the 72V series. It features a storage capacity of 36K bits, organized as 4K words by 9 bits. The device operates with a maximum data rate of 22.2 MHz and provides a typical access time of 35 ns. It supports unidirectional bus operation and includes relay capability for data retransmission. The component is housed in a 32-PLCC package and functions within a supply voltage range of 3 V to 3.6 V.

FIFOs Memory Feature Summary

• Asynchronous first-in-first-out memory architecture supporting independent read and write clock domains
• Integrated relay capability enabling data retransmission without host intervention
• Unidirectional data bus interface designed for parallel data transfer applications

FIFOs Memory Applications

• Data buffering between asynchronous system components
• Clock domain crossing interfaces in digital logic circuits
• Temporary data storage in high-speed communication protocols

FIFOs Memory Procurement Notes

Verify current availability status as this component may be discontinued or subject to limited supply constraints. Confirm RoHS compliance requirements against specific project standards, noting that older revisions may not meet current environmental directives. Validate package integrity upon receipt due to potential moisture sensitivity handling requirements during storage and shipping.

FIFOs Memory Selection Notes

Select this component when a 4Kx9 asynchronous FIFO with 35 ns access speed is required. Ensure the design accommodates the 32-PLCC surface mount package dimensions. Verify that the system power supply remains stable within the 3 V to 3.6 V operating range. Consider the unidirectional nature of the data bus when designing the interface logic.

FIFOs Memory Part Context

This part belongs to the Renesas 72V series of asynchronous FIFOs, which are widely used for temporary data storage and synchronization in electronic systems. The 72V04 variant specifically offers 36K-bit capacity. Similar parts in the family include variants with different access times or organization structures, such as the 72V04L25 series.

FIFOs Memory Replacement Considerations

Check for direct pin-compatible substitutes within the 72V04 family, such as the 72V04L25JI8, if faster access times are acceptable. Verify that any replacement maintains the same 32-PLCC package and 3.3V operating voltage specifications.
