71V416S15BEI

Overview

The 71V416S15BEI is a 4 Mbit (256K x 16) asynchronous static random-access memory manufactured by Renesas Electronics. It operates on a single 3.3 V supply with a voltage range of 3 V to 3.6 V. The device features a 15 ns access time and utilizes a parallel interface. It is housed in a 48-CABGA package measuring 9x9 mm. The component supports surface mount installation and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Fully static asynchronous circuitry requiring no clocks or refresh cycles for operation
• LVTTL-compatible bidirectional inputs and outputs for direct logic interfacing
• Center power and ground pinout configuration for improved signal integrity

Applications

• High-speed data buffering in embedded systems
• Cache memory implementation in industrial controllers
• Data storage in telecommunications equipment

Procurement Notes

Verify the exact suffix against official Renesas documentation, as variations may indicate different packaging or environmental ratings. Confirm current availability status, as this component series has faced end-of-life notifications. Ensure compatibility with existing PCB footprints and verify moisture sensitivity levels before assembly.

Selection Notes

Select this part when a 15 ns access speed is required for 16-bit wide data paths. The CABGA package offers a compact footprint suitable for space-constrained designs. Consider the extended industrial temperature range if the application operates in harsh environments. Verify that the LVTTL input/output levels match the driving system's logic standards.

Part Context

This component belongs to the 71V416 family of high-speed CMOS SRAMs. The 'S' designation typically indicates specific performance or packaging variants within the broader 71V416 series. These devices are designed for applications requiring fast, non-volatile-like data retention without the complexity of synchronous interfaces.

Replacement Considerations

Official substitutes include the 71V416S15PHGI and 71V416S15YG8. Verify pin compatibility and package dimensions before substitution. Note that some alternatives may have different temperature ranges or packaging types.
