72V255LA20PF8

FIFOs Memory Overview

The 72V255LA20PF8 is a synchronous FIFO memory integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 144K bits, organized as 8K words by 18 bits. The device supports unidirectional data transfer with a maximum data rate of 50MHz and an access time of 12ns. It operates within a supply voltage range of 3V to 3.6V and draws a maximum supply current of 55mA. The component is housed in a 64-TQFP (14x14) surface-mount package and functions reliably across a commercial temperature range of 0°C to 70°C.

FIFOs Memory Feature Summary

• Supports First-Word-Fall-Through (FWFT) mode for immediate data availability upon read enable assertion.
• Includes programmable status flags to indicate full, empty, and near-full conditions.
• Provides relay capability to maintain data integrity during power transitions or bus releases.

FIFOs Memory Applications

• High-speed data buffering between asynchronous logic domains
• Data acquisition systems requiring precise timing control
• Communication interface bridging with flow control management

FIFOs Memory Procurement Notes

Verify the specific suffix 'PF8' against official Renesas documentation to confirm tape-and-reel packaging versus tray options. Confirm RoHS compliance status as older variants may not meet current environmental standards. Check for active discontinuation notices or last-time-buy deadlines directly from the manufacturer before finalizing procurement plans.

FIFOs Memory Selection Notes

Select this component when a 18-bit wide synchronous FIFO with 8K depth is required. Ensure the system clock does not exceed 50MHz to meet the 12ns access time specification. Verify that the 3V to 3.6V operating voltage aligns with the target platform's power rails. Consider the 64-pin TQFP footprint for PCB layout constraints.

FIFOs Memory Part Context

This part belongs to the Renesas 72V series of high-performance synchronous FIFOs. It shares architectural similarities with the 72V255L15TF but offers different speed grades and packaging options. The 72V family is designed for applications demanding reliable data buffering with low latency and flexible configuration options for industrial and communication systems.

FIFOs Memory Replacement Considerations

The IDT72V255LA20PF is listed as an alias for this component. Verify pinout and electrical specifications compatibility before substituting with other 72V series parts like the 72V255L15TF, noting differences in access times and package types.
