Description

The 24AA52-I/MS is an Electrically Erasable PROM that falls under the Memory product category. It is designed and manufactured by Microchip Technology Inc. and is capable of operating across a broad range of voltages, from 1.8V to 5.5V. This device comes with a software write-protect feature for the lower half of the array, as well as an external pin that can be used to write-protect the entire array. This feature allows the system designer to protect none, half, or all of the array, depending on the needs of the application.

Application Scenarios

The 24AA52-I/MS can be used in various electronic applications where data storage and retrieval is an essential requirement. Some of the typical applications of the device include but are not limited to:

• Sensor Calibration Data Storage
• Low-Power Data Logging
• Configuration Data Storage for Industrial Systems
• System Identification and Authentication
• User Settings and Preferences Storage

Comparison

• Low-Power Consumption: The device has a standby current of 1μA typical which results in low-power consumption.
• Data Retention: The device offers over 200 years of data retention, making it a reliable choice for long-term storage.
• Flexibility: The device has software write-protect features and separate hardware write-protect pin that offers flexibility to the system designer to protect the required area.

• Small Storage: The 24AA52-I/MS offers 2 Kbit memory storage which makes it unsuitable for high storage requirements.
• Low Write Cycle Endurance: The device has a write cycle endurance of 1,000,000 which may not be suitable for high write cycle applications.
