71V416L15BEGI

Overview

The IDT71V416L15BEGI is a 4Mbit (256K x 16) asynchronous static random-access memory manufactured by Renesas Electronics. It operates on a single 3.0V to 3.6V power supply and features a 15ns access time with a 15ns write cycle time. The device utilizes a parallel interface and is housed in a 48-CABGA package measuring 9x9mm. It supports surface mount installation and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Fully static asynchronous architecture requiring no clock signals or periodic refresh cycles for operation.
• Bidirectional inputs and outputs are LVTTL-compatible, ensuring direct interfacing with standard logic families.
• Center power and ground pin configuration optimizes signal integrity and reduces noise coupling.

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Industrial control system data storage

Procurement Notes

Verify the specific suffix BEGI against official Renesas documentation to confirm package dimensions and lead finish specifications. Confirm RoHS compliance status as historical records indicate potential non-compliance for earlier variants. Check for active obsolescence notices or product change notifications that may affect long-term availability.

Selection Notes

Select this component when a 256K x 16 organization is required with 15ns performance levels. Ensure the design accommodates the 48-CABGA footprint and 3.3V logic levels. Consider alternative packages like TSOP if board space constraints differ from the BGA layout requirements.

Part Context

This part belongs to the 71V416L series of high-performance CMOS SRAMs. It shares architectural similarities with other members of the family but differs in access speed and physical packaging. The CABGA variant offers a compact solution for dense PCB layouts compared to traditional leaded packages.

Replacement Considerations

Officially documented substitutes include the 71V416L15BEG. Verify electrical compatibility and pinout alignment before substitution.
