72205LB25J8

Overview

The Renesas Electronics Corporation 72205LB25LB25J8 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 data rates up to 40 MHz with an access time of 15 ns. The component features unidirectional bus direction and programmable flags support. It is housed in a 64-TQFP surface-mount package measuring 10x10 mm and functions across a temperature range of -40°C to 85°C.

Feature Summary

• Synchronous first-in-first-out memory architecture for reliable data buffering
• Programmable flag support for status monitoring
• Unidirectional data bus configuration

Applications

• Data buffering in high-speed digital systems
• Interprocessor communication interfaces
• Network equipment signal processing

Procurement Notes

Verify the exact suffix J8 against official datasheets to confirm pinout and electrical specifications. Confirm RoHS compliance status as sources indicate non-compliance. Check moisture sensitivity level requirements for handling. Validate lead-free status if required by assembly processes. Ensure availability through authorized channels due to potential discontinuation.

Selection Notes

Select this component when a 256x18 synchronous FIFO is required with 15 ns access speed. Consider the 64-TQFP package for surface mount applications. Verify operating temperature range meets environmental needs. Compare against other 7200 series variants for different capacities or speeds.

Part Context

This part belongs to the Renesas 7200 series of synchronous FIFOs. It shares architectural similarities with other members like the 72215LB25J but differs in depth and organization. The series is designed for general-purpose data buffering in telecommunications and computing applications.

Replacement Considerations

Check for direct substitutes within the IDT/Renesas 72205 family. Verify pin compatibility before replacing with similar FIFO devices from other manufacturers.
