71V416L12BE

Overview

The Renesas Electronics Corporation 71V416L12BE is a 4 Mbit (256K x 16) asynchronous static random-access memory (SRAM) IC. It operates on a single 3.3 V power supply with a voltage range of 3.0 V to 3.6 V. The device features a maximum access time of 12 ns and a write cycle time of 12 ns. It utilizes a parallel interface and is housed in a 48-CABGA (9x9 mm) surface-mount package. The component supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Fully static asynchronous circuitry requiring no clock or refresh cycles for operation.
• Bidirectional inputs and outputs are LVTTL-compatible for direct logic interfacing.
• Center power and ground pinout design to optimize signal integrity and reduce noise.

Applications

• High-speed data buffering in embedded systems
• Cache memory implementation in microcontroller units
• Industrial control system data storage
