72V845L10PF

FIFOs Memory Overview

The Renesas Electronics Corporation 72V845L10PF is a dual synchronous First-In-First-Out (FIFO) memory device. It provides a total storage capacity of 144 kilobits, organized as two independent 4K x 18-bit FIFOs. The component supports data transfer rates up to 100 MHz with a maximum access time of 6.5 nanoseconds. It operates within a supply voltage range of 3.0 V to 3.6 V and draws a maximum supply current of 60 mA. The device features bidirectional data buses and programmable status flags. It is housed in a 128-pin Thin Quad Flat Package (TQFP) with dimensions of 14 mm by 20 mm.

FIFOs Memory Feature Summary

• Dual independent FIFO architecture allowing simultaneous or separate operation of two 4K x 18 memory blocks
• Supports both synchronous and asynchronous clocking modes for flexible system integration
• Bidirectional data bus capability enables efficient data flow management in complex designs
• Integrated programmable flags provide real-time status monitoring for empty and full conditions

FIFOs Memory Applications

• High-speed data buffering between processors and peripheral devices
• Protocol conversion interfaces requiring width expansion or depth adjustment
• Real-time signal processing systems needing low-latency data staging
• Network equipment managing packet prioritization and traffic flow control

FIFOs Memory Procurement Notes

Verify the specific suffix requirements for your design, as package variations exist within this series. Confirm that the 3.0 V to 3.6 V operating voltage aligns with your system power rails. Check for RoHS compliance status if environmental regulations apply to your deployment. Ensure the 128-pin TQFP footprint matches your PCB layout constraints before finalizing procurement.

FIFOs Memory Selection Notes

Select this component when dual-channel synchronization is required within a single integrated circuit. The 100 MHz speed rating suits applications demanding rapid data throughput without external buffering delays. Consider the 18-bit word width for specialized data paths that do not fit standard 8-bit or 16-bit architectures. Evaluate the 128-pin package size against available board space and thermal dissipation capabilities.
