Overview
The 72255LA15PFGI is a synchronous FIFO memory IC manufactured by Renesas Electronics. It provides a storage capacity of 144K bits, organized as 8K words by 18 bits. The device supports unidirectional data transfer with a maximum data rate of 66.7MHz and an access time of 10ns. It operates within a supply voltage range of 4V to 5.5V and has a maximum supply current of 80mA. The component is housed in a 64-TQFP package measuring 14x14mm.
Feature Summary
- Synchronous operation for reliable data buffering
- Unidirectional bus directionality
- Supports programmable flags
- Includes relay capability
Applications
- Data buffering in high-speed digital systems
- Interface bridging between asynchronous logic blocks
- Temporary storage in communication protocols
Procurement Notes
Verify the specific suffix PFGI against official Renesas documentation to confirm package dimensions and pinout compatibility. Confirm RoHS compliance status as sources vary. Check for End-of-Life (EOL) notices or Product Change Notifications (PCN) regarding assembly site changes or label updates before finalizing procurement plans.
Selection Notes
Select this component when a synchronous FIFO with 18-bit word width is required. Ensure the system voltage aligns with the 4V to 5.5V operating range. Verify that the 64-TQFP package fits the PCB footprint constraints. Consider the 10ns access time relative to the system clock speed to ensure timing margins are met.
Part Context
This part belongs to the 72255 series of synchronous FIFOs from Renesas. It shares functional similarities with other members like the 72V255LA15PFI but differs in supply voltage requirements and specific electrical characteristics. The 72255 series is designed for applications requiring moderate depth and wide data paths.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Renesas technical support for direct replacements or cross-reference with similar 8K x 18 synchronous FIFOs if pin-compatible alternatives are needed.
