71V416L15BE

Overview

The Renesas Electronics Corporation 71V416L15BE is a 4 Mbit (256K x 16) asynchronous static random-access memory (SRAM) integrated circuit. It operates on a single 3.3 V power supply within the range of 3 V to 3.6 V and features a 15 ns access time. The device utilizes a parallel interface and is housed in a 48-CABGA (9x9 mm) surface-mount package. Designed for industrial applications, it supports an operating temperature range from 0°C to 70°C.

Feature Summary

• Fully static asynchronous operation requiring no clock signals or periodic refresh cycles
• Single 3.3 V CMOS technology with LVTTL-compatible bidirectional inputs and outputs
• Center power and ground pinout configuration for improved signal integrity

Applications

• Industrial control systems requiring non-volatile data retention during power transitions
• Embedded storage buffers in telecommunications equipment
• Data acquisition systems utilizing high-speed parallel memory interfaces

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements as this specific variant may not meet current environmental standards. Validate package markings against official datasheets to prevent counterfeit substitution. Ensure supply chain stability given potential discontinuation risks associated with legacy memory products.

Selection Notes

Select this component when a 256K x 16 organization is required with 15 ns speed performance. The 48-CABGA package suits designs needing compact surface-mount solutions. Consider voltage compatibility with 3.3 V logic families. Evaluate thermal management capabilities for the 0°C to 70°C operating range in enclosed industrial enclosures.
