Overview

The CY14B256LA-SZ25XIT is a 256Kbit non-volatile SRAM (nvSRAM) organized as 32K x 8 bits. It combines a high-performance SRAM with a non-volatile QuantumTrap cell, allowing for 25ns fast access times while ensuring data is automatically backed up to flash during power loss without the need for a battery.

Why Choose This Part

This device offers infinite SRAM read/write endurance and 20-year data retention at 85 degrees Celsius. By utilizing an internal capacitor for the AutoStore function, it eliminates the maintenance and reliability issues associated with external batteries in non-volatile memory applications.

Applications

Industrial Automation Controllers
Used for real-time logging of system states and configuration parameters that must survive unexpected power outages.
Data Logging Equipment
Ideal for high-frequency writing of sensor data where traditional EEPROM endurance would be insufficient.
RAID Controllers
Functions as a high-speed cache for storing dirty bit maps and metadata to prevent data corruption during power cycles.
Motor Control Systems
Stores critical shaft position and calibration data that requires immediate availability upon system boot.

Getting Started

Designers should interface the 32-pin SOIC via a standard parallel memory bus and ensure a small capacitor is placed on the VCAP pin to power the AutoStore sequence. During firmware development, verify that the HSB (Hardware Store Busy) signal is monitored to prevent memory access during non-volatile store operations.

Also Consider

FM24V02A IFXInfineon Technologies - F-RAM alternative with an I2C interface for designs where pin count is more critical than parallel access speed.
