Overview
The 72205LB25TF8 is a synchronous first-in, first-out memory device manufactured by Renesas Electronics. It features 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 has a maximum supply current of 60mA. The device is housed in a 64-TQFP package measuring 10x10mm.
Feature Summary
- Synchronous FIFO architecture for reliable data buffering
- Unidirectional bus direction for dedicated data flow
- Supports programmable flags for status monitoring
Applications
- Data buffering in high-speed digital systems
- Interprocessor communication interfaces
- Network interface data handling
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels due to discontinuation status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check moisture sensitivity level (MSL 3) handling procedures during storage and assembly to prevent damage. Validate package dimensions against design specifications before integration.
Selection Notes
Select this component when a synchronous FIFO with 18-bit width and 256-word depth is required. Ensure the system clock frequency does not exceed 40MHz to maintain specified 15ns access times. Verify that the operating voltage aligns with the 4.5V to 5.5V range. Consider the 64-TQFP package size for PCB layout constraints.
Part Context
This part belongs to the 7200 series of synchronous FIFOs from Renesas Electronics. It is related to other variants such as the 72215LB25PF8 and 72235LB25TF8, which offer different memory depths but similar operational characteristics. The series is designed for applications requiring efficient data buffering between asynchronous or synchronous domains.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, alternative components must be evaluated based on functional equivalence, including memory organization, speed, and package compatibility.
