72271LA15PF8

Overview

The Renesas 72271LA15PF8 is a synchronous FIFO memory device with a capacity of 288K bits, organized as 32K words by 9 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 66.7 MHz with a 10 ns access time. The component features unidirectional bus directionality and is housed in a 64-TQFP (14x14) surface-mount package. It supports depth and width expansion for system scalability.

Feature Summary

• Supports both depth and width expansion for cascading multiple devices to increase memory capacity or widen data buses.

Applications

• Data buffering in high-speed digital systems
• Clock domain crossing applications
• Interface bridging between asynchronous components

Procurement Notes

Verify the exact suffix configuration against official Renesas documentation, as variations may exist. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for end-of-life notices or alternative part recommendations from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a synchronous FIFO with 9-bit word width and 32K depth is required. Ensure the system operates within the 4.5 V to 5.5 V supply range. Consider the 64-TQFP package constraints for PCB layout and thermal management during the design phase.

Part Context

This part belongs to the Renesas 72271 series of synchronous FIFOs. It is designed for high-performance data storage and transfer applications requiring predictable timing characteristics. The series typically offers various organization options and speeds to suit different system bandwidth needs.

Replacement Considerations

Check for direct pin-compatible substitutes within the same family. Verify electrical parameters such as voltage range and access times match the original design requirements before substituting.
