72V851L15PF

FIFOs Memory Overview

The 72V851L15PF is a synchronous dual First-In, First-Out (FIFO) memory device manufactured by Renesas Electronics. It features a storage capacity of 144K bits, organized as two independent 8K x 9 bit blocks. The component supports bidirectional data transfer with a maximum clock frequency of 66.7MHz and an access time of 10ns. It operates within a supply voltage range of 3V to 3.6V and draws a maximum supply current of 40mA. The device is housed in a 64-pin TQFP package measuring 14x14mm and is rated for operation between 0°C and 70°C.

FIFOs Memory Feature Summary

• Dual independent FIFO architecture supporting simultaneous or separate operations
• Bidirectional bus direction capability for flexible data routing
• Programmable status flags for monitoring full and empty conditions

FIFOs Memory Applications

• Data buffering in high-speed digital signal processing systems
• Interprocessor communication interfaces requiring asynchronous data handling
• Network interface card data staging and protocol conversion

FIFOs Memory Procurement Notes

Verify the specific suffix PF against official Renesas documentation to confirm the 64-TQFP package configuration. Confirm RoHS compliance status as historical records indicate potential non-compliance for this series. Check for active discontinuation notices or lifecycle changes before finalizing procurement plans.

FIFOs Memory Selection Notes

Select this component when a synchronous dual FIFO with bidirectional support is required. Ensure the system design accommodates the 3V to 3.6V operating voltage range. Verify that the 66.7MHz clock speed meets the application timing requirements and that the 64-pin TQFP footprint fits the PCB layout constraints.

FIFOs Memory Part Context

This part belongs to the 72V851 series of synchronous FIFOs from Renesas. It shares architectural similarities with other members like the 72V851L20PF but offers faster performance characteristics. The series is designed for general-purpose memory buffering applications in industrial and telecommunications equipment.

FIFOs Memory Replacement Considerations

The 72V851L10PFG is listed as an upgrade replacement option. Verify pin compatibility and electrical specifications before substitution.
