72V235L15PFI8

FIFOs Memory Overview

The Renesas Electronics Corporation 72V235L15PFI8 is a synchronous FIFO memory integrated circuit designed for high-speed data buffering applications. It features a storage capacity of 36K bits, organized as 2K words by 18 bits. The device supports unidirectional bus operation with a maximum data rate of 66.7MHz and an access time of 10ns. It operates within a supply voltage range of 3V to 3.6V and draws a maximum supply current of 30mA. The component is housed in a 64-LQFP surface-mount package and is rated for industrial operating temperatures from -40°C to 85°C.

FIFOs Memory Feature Summary

• Synchronous single-clock architecture ensures reliable data transfer between asynchronous system domains without complex handshaking logic.
• Configurable flag outputs provide programmable status indicators for full, empty, and near-full conditions to manage buffer flow control.

FIFOs Memory Applications

• Data buffering in telecommunications equipment requiring high-throughput interface management
• Digital signal processing systems needing temporary storage for sampled data streams
• High-speed computer peripherals managing data transfer rates between components

FIFOs Memory Procurement Notes

Verify the specific suffix configuration against official documentation, as packaging variations such as tape-and-reel or tube formats may exist within the product family. Confirm RoHS compliance status, as manufacturing changes can affect environmental certifications. Check for end-of-life notices or production change notifications that might impact long-term availability or sourcing strategies for this discontinued component.

FIFOs Memory Selection Notes

Select this component when a synchronous FIFO with 18-bit word width and 2K depth is required for unidirectional data paths. Ensure the system power supply aligns with the 3V to 3.6V operating range. Consider the 64-LQFP package dimensions for PCB layout constraints. Verify that the 10ns access time meets the timing requirements of the target clock frequency up to 66.7MHz.

FIFOs Memory Part Context

This part belongs to the 72V series of synchronous FIFOs from Renesas Electronics, formerly IDT. The series offers various configurations in terms of word width, depth, and speed grades. The 72V235 variant specifically targets applications requiring moderate density and high-speed performance in a compact surface-mount package suitable for dense board designs.

FIFOs Memory Replacement Considerations

Consult official substitution guides for compatible parts within the same family, such as the 72V235L15PFGI8, which shares similar electrical characteristics but may differ in packaging or compliance specifications. Verify pinout compatibility and functional equivalence before replacement.
