72T1895L5BB

FIFOs Memory Overview

The Renesas 72T1895L5BB is a high-speed TeraSync FIFO memory device operating at 2.5V with a supply range of 2.375 V to 2.625 V. It features asynchronous and synchronous modes, supporting data rates of 83 MHz and 200 MHz with access times of 10 ns and 3.6 ns respectively. The memory configuration is 64K x 18 or 128K x 9, housed in a 144-PBGA (13x13) package. Maximum supply current is 60 mA.

FIFOs Memory Feature Summary

• Supports flexible Bus-Matching x18/x9 data flow configurations
• Features clocked read and write controls for precise timing
• Operates in both asynchronous and synchronous modes

FIFOs Memory Applications

• Data rate matching in network interface cards

FIFOs Memory Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is restricted, and sourcing may require checking secondary distributors or existing stock. Verify RoHS compliance status and moisture sensitivity level before integration into new designs due to end-of-life status.

FIFOs Memory Selection Notes

Select this part for applications requiring 2.5V operation with specific 144-pin BGA footprint constraints. Compare against the 72T1885L5BB for smaller capacity needs or the 72T1865L5BB for different depth requirements. Ensure design compatibility with the 13x13 mm package dimensions and thermal characteristics.

FIFOs Memory Part Context

Part of the Renesas 72T series TeraSync FIFO family, designed for high-performance memory buffering. This model specifically targets 2.5V logic interfaces with configurable data bus widths. It shares architectural similarities with other 72T devices but offers distinct capacity and pinout options within the PBGA form factor.

FIFOs Memory Replacement Considerations

No direct public substitute part numbers are confirmed for this obsolete component. Designers should evaluate alternative FIFO families from Renesas or other manufacturers that match the 144-PBGA package and 2.5V voltage specifications.
