72815LB25PF

FIFOs Memory Overview

The Renesas 72815LB25PF is a synchronous dual FIFO memory device featuring two independent 512 x 18-bit First-In-First-Out buffers within a single package. It operates on a 4.5 V to 5.5 V supply with a maximum data rate of 40 MHz and an access time of 15 ns. The component utilizes a 128-pin TQFP (14x20 mm) surface-mount package. Key functional attributes include bidirectional bus direction, programmable status flags, and First Word Fall Through (FWFT) support.

FIFOs Memory Feature Summary

Dual independent FIFO architecture providing separate read and write control for each buffer
Supports both single-clock and asynchronous dual-clock operation modes
Integrated programmable status flags indicating empty, full, and half-full conditions
First Word Fall Through capability for fixed low latency data retrieval

FIFOs Memory Applications

Optical disk controller data buffering
Local area network (LAN) interface buffering
Interprocessor communication link management

FIFOs Memory Procurement Notes

This component is officially discontinued and no longer in production. Verification of availability is restricted to existing stock or surplus channels only. Confirm RoHS compliance status as the datasheet indicates non-compliance. Ensure moisture sensitivity level handling protocols are followed during storage and assembly processes.

FIFOs Memory Selection Notes

Select this part when a compact solution for dual-channel data buffering is required without pin-count expansion. It serves as a direct functional replacement for two separate 72225 FIFO units. Verify that the system requires 18-bit word width and 512-word depth per channel before implementation.

FIFOs Memory Part Context

Part of the 72815L series within the broader 7200 family of synchronous FIFO memories. This specific model represents the 15 ns speed grade variant. It shares architectural similarities with other members like the 72815LB10PF but differs in clock speed specifications.
