72205LB15PF8

Overview

The Renesas Electronics 72205LB15PF8 is a synchronous FIFO memory device with a storage capacity of 4.5K bits, organized as 256 words by 18 bits. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum data rate of 40 MHz with an access time of 15 ns. The component is housed in a 64-TQFP package and functions as a unidirectional buffer. It features programmable flags for status monitoring and is designed for surface mount installation.

Feature Summary

• Synchronous first-in, first-out memory architecture with clocked read and write controls
• Unidirectional bus direction supporting 18-bit data width
• Programmable flag support for full and empty status indication
• Surface mount TQFP-64 packaging for compact integration

Applications

• Data buffering in high-speed digital systems
• Interface bridging between asynchronous logic domains
• Signal processing pipeline staging

Procurement Notes

Verify the specific suffix PF8 against official Renesas documentation to confirm pinout and package dimensions. Confirm RoHS compliance status as sources indicate non-compliance. Check for End-of-Life notices or discontinuance announcements prior to procurement. Ensure moisture sensitivity handling procedures are followed during assembly.

Selection Notes

Select this component when a 256x18 synchronous FIFO is required. Verify that the 40 MHz operating speed meets system timing requirements. Ensure the design accommodates the 64-pin TQFP footprint. Consider alternative packages if lead-free compliance is mandatory for the application.

Part Context

This part belongs to the 72205LB series of synchronous FIFOs from Renesas Electronics. It is functionally related to other members of the 722xx family but differs in density and speed grades. The LB designation typically indicates low-power CMOS technology compatible with 5V logic levels.
