72205LB25PF

Overview

The Renesas 72205LB25PF is a synchronous FIFO memory device belonging to the 7200 series. It provides a storage capacity of 4.5K bits, organized as 256 words by 18 bits. The component supports unidirectional data transfer with a maximum data rate of 40MHz and an access time of 15ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 60mA. The device is housed in a 64-pin TQFP package measuring 10x10mm and is rated for industrial temperatures from -40°C to 85°C.

Feature Summary

• Synchronous operation with dedicated read and write clock inputs for reliable data buffering
• Programmable status flags indicating full, empty, and almost-full conditions
• CMOS technology ensuring low power consumption and high-speed performance

Applications

• Data buffering in graphics systems
• Local area network interface buffering
• Interprocessor communication links

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package dimensions against design specifications before integration. Check for available replacement alternatives if long-term supply stability is required for production.

Selection Notes

Select this component when a 256x18 synchronous FIFO is required for moderate-speed data buffering applications. Ensure the system design accommodates the 64-TQFP package footprint and thermal characteristics. Verify that the 40MHz operating frequency meets the timing constraints of the connected processors or peripherals.

Part Context

This part belongs to the IDT 72205 family of synchronous FIFOs, now manufactured under the Renesas Electronics brand following corporate acquisitions. The 7200 series is designed for general-purpose memory buffering tasks requiring simple interface control and predictable latency.

Replacement Considerations

Check for direct pin-compatible substitutes within the 72205LB series. Consider the 72205LB25TFI for identical electrical specifications in a TQFP package.
