72V285L15PFGI8

FIFOs Memory Overview

The Renesas 72V285L15PFGI8 is a synchronous FIFO memory device featuring a storage capacity of 1.125M bits, organized as 64K words by 18 bits. It supports unidirectional data transfer with a maximum clock frequency of 66.7 MHz and an access time of 10 ns. The component operates within a supply voltage range of 3 V to 3.6 V and has a maximum supply current of 55 mA. It is housed in a 64-TQFP package and functions across a temperature range of -40°C to +85°C.

FIFOs Memory Feature Summary

• Synchronous operation with programmable full/empty flags
• Unidirectional data bus architecture for dedicated flow control
• Integrated parity generation and checking logic
• Supports daisy-chaining for expanded memory configurations

FIFOs Memory Applications

• High-speed data buffering in telecommunications equipment
• Interface bridging between asynchronous system components
• Data acquisition systems requiring precise timing alignment
• Network switch buffer memory applications

FIFOs Memory Procurement Notes

Verify RoHS compliance status carefully, as the specific suffix GI8 indicates lead-free packaging which may differ from older non-GI variants. Confirm end-of-life status through official Renesas notices, as discontinuation dates vary by region. Ensure moisture sensitivity level (MSL 3) handling protocols are strictly followed during assembly to prevent package damage. Cross-reference datasheet revisions to confirm pinout consistency with existing designs.

FIFOs Memory Selection Notes

Select this component when unidirectional synchronous buffering is required for 18-bit wide data paths. The 66.7 MHz speed class suits moderate-to-high throughput applications without the complexity of dual-port RAM. Consider the 64-TQFP package constraints for PCB layout density. Evaluate power consumption against thermal management capabilities in enclosed environments due to the specified operating temperature range limits.

FIFOs Memory Part Context

This part belongs to the Renesas 72V series of high-performance synchronous FIFOs, originally developed under IDT branding. The series is characterized by low power consumption and flexible configuration options including parity support. The 72V285 variant specifically targets 18-bit width applications, distinguishing it from the 9-bit or 36-bit counterparts in the same family.

FIFOs Memory Replacement Considerations

Official substitutes include the 72V285L10PFGI8 for faster 100 MHz performance or the 72V281L15PFI8 for 9-bit width requirements. Verify pin compatibility before substitution, as package variations exist within the series. Check for updated RoHS directives if replacing legacy IDT-branded inventory.
