Overview
The 72255LA10PFG is a synchronous FIFO memory device manufactured by Renesas Electronics. It features an 8K x 18 bit architecture, providing a total storage capacity of 144K bits. The component supports unidirectional data transfer with a maximum data rate of 100MHz and an access time of 8ns. It operates within a supply voltage range of 4V to 5.5V. The device is housed in a 64-pin TQFP package (14x14mm) and includes First-Word-Fall-Through (FWFT) support.
Feature Summary
- Synchronous operation with unidirectional data flow capability
- Integrated First-Word-Fall-Through (FWFT) functionality for reduced latency
- High-speed data handling supporting up to 100MHz clock rates
Applications
- High-speed digital signal processing interfaces
- Data buffering in communication systems
- Memory expansion for microcontroller applications
Procurement Notes
This component is scheduled for obsolescence and will be discontinued by the manufacturer. Verify current availability status through authorized distributors before design finalization. Ensure compliance with RoHS directives and check moisture sensitivity levels for proper handling during assembly processes.
Selection Notes
Select this part for applications requiring reliable synchronous buffering with FWFT support. Consider the 4V to 5.5V operating range when designing power supplies. Note that the device is obsolete; evaluate alternative components from the same family or newer generations for long-term production viability.
Part Context
The 72255LA10PFG belongs to the 72V265/72255 series of SuperSync FIFOs from Renesas. These devices are designed for high-performance data buffering needs. The specific model offers 8K depth and 18-bit width, distinguishing it from other variants like the 72V265LA10PFG which may have different capacities or speed grades.
Replacement Considerations
As the 72255LA10PFG is obsolete, consider equivalent parts such as the IDT72255L10PFG or compatible SuperSync FIFOs from Renesas. Verify pin compatibility and electrical specifications before substitution.
