72V253L6PFG

FIFOs Memory Overview

The Renesas 72V253L6PFG is a synchronous FIFO memory device featuring a storage capacity of 72K bits, organized as 4K x 18 or 8K x 9. It operates with a maximum clock frequency of 166MHz and an access time of 4ns. The component supports unidirectional data transfer and functions within a supply voltage range of 3.15 V to 3.45 V. It is housed in an 80-TQFP (14x14) surface-mount package and is rated for operation between 0°C and 70°C.

FIFOs Memory Feature Summary

• Supports First-Word-Fall-Through (FWFT) mode for immediate data availability upon write completion.
• Includes programmable flags and relay capability for flexible status monitoring and signal buffering.
• Offers configurable depth and width organization to adapt to varying system bus requirements.

FIFOs Memory Applications

• High-speed data buffering in telecommunications equipment
• Interface bridging between asynchronous logic domains
• Data acquisition systems requiring precise timing control

FIFOs Memory Procurement Notes

Verify the specific suffix 'PFG' against official Renesas documentation to confirm RoHS compliance and lead-free status, as packaging variations exist within the series. Confirm that the 80-TQFP package matches your PCB footprint requirements. Check for any recent Product Change Notices regarding pinout or electrical parameter updates before finalizing procurement.

FIFOs Memory Selection Notes

Select this component when a unidirectional synchronous FIFO with 4ns access time is required. Ensure the design accommodates the 3.3V nominal supply voltage range. Consider the 80-pin TQFP package constraints for thermal management and board space. Verify that the 166MHz maximum clock speed aligns with the system's timing budget.

FIFOs Memory Part Context

This part belongs to the Renesas 72V Super Sync II family of high-performance synchronous FIFOs. The series is designed for applications demanding low latency and high throughput. The 72V253 variant specifically provides 72K-bit capacity with flexible word widths, distinguishing it from other members like the 72V273 or 72V3650 which offer different capacities or bus widths.

FIFOs Memory Replacement Considerations

Direct substitutes include the 72V253L6BC in a CABGA package. Verify pin compatibility and electrical specifications before substitution. Other family members may require significant circuit redesign due to differing capacities or interface characteristics.
