Overview

The CY62146EV30LL-45BVXI is a high-performance 4Mbit asynchronous CMOS static RAM organized as 256K words by 16 bits. Part of the MoBL (More Battery Life) family, it is designed for low-power applications with an ultra-low standby current of 2.5 microamps and an automatic power-down feature when the chip is deselected.

Why Choose This Part

This SRAM offers a wide operating voltage range from 2.2V to 3.6V, making it compatible with various low-voltage logic levels. Its MoBL technology ensures significantly reduced power consumption in both active and standby modes, which is critical for extending the operating life of portable electronic systems.

Applications

Handheld Devices
Ideal for battery-powered instruments and handheld terminals requiring high-density volatile storage with minimal power drain.
Industrial Controllers
Used as external data memory for microcontrollers in industrial automation systems where reliable asynchronous timing is required.
Embedded Buffer Memory
Provides a 45 ns access time buffer for communication processors and networking equipment to manage data bursts.

Getting Started

To integrate this memory, ensure the MCU or FPGA memory controller supports asynchronous parallel interfaces with a 16-bit wide data bus. Standard 48-ball VFBGA soldering profiles should be followed, and decoupling capacitors should be placed close to the VDD pins to manage the 15mA peak active current at maximum frequency.
