Overview

The CY62126EV30LL-45ZSXI is a high-performance 1Mbit CMOS static RAM organized as 64K words by 16 bits. This asynchronous memory device operates within a voltage range of 2.2V to 3.6V, making it suitable for low-power handheld and industrial applications that require reliable data retention with minimal standby current.

Why Choose This Part

The device features an automatic power-down feature that significantly reduces power consumption when the chip is deselected via Chip Enable. Its 45ns access time ensures high-speed data retrieval, while the 44-pin TSOP II package provides a standard footprint for compact PCB layouts.

Applications

Industrial Controller Buffer
Used as a high-speed workspace for industrial PLCs or data loggers requiring 45ns access times.
Low-Power Handheld Devices
Ideal for battery-operated equipment due to its ultra-low 1uA typical standby current.
Communication Hardware
Acts as a packet buffer or temporary data storage in networking equipment and communication interfaces.
Legacy System Maintenance
Provides a drop-in replacement for older 1Mb 16-bit parallel SRAMs in existing embedded designs.
