REN71V416S12PHGI8

Overview

The 71V416S12PHGI8 is a high-speed 4-Megabit asynchronous CMOS Static RAM organized as 256K x 16 bits. Operating on a 3.3V power supply, it features a fast 12ns access time and is designed for applications requiring high-performance memory without the complexity of synchronous clocking. This industrial-grade component is housed in a 44-pin TSOP package and supports a wide operating temperature range from -40C to +85C.

Why Choose This Part

The device offers a 12ns access time and requires no clock or refresh cycles, simplifying the hardware interface and controller logic. Its 3.3V LVTTL-compatible inputs and outputs allow for direct interfacing with most modern microprocessors and FPGAs. The industrial temperature rating and low standby current of 50mA make it suitable for rugged and power-sensitive environments.

Applications

Getting Started

To integrate this SRAM, connect the 18-bit address bus and 16-bit data bus to your processor's external memory controller. Ensure proper decoupling with 0.1uF capacitors placed close to the VDD pins to handle the 170mA peak run current. Typical implementation involves using the Chip Enable (CE), Output Enable (OE), and Write Enable (WE) pins alongside Upper/Lower Byte control pins for 8-bit or 16-bit access.
