ON Semiconductor CAT24S64C4ATR EEPROM

The CAT24S64C4ATR is a high-performance, 64-Kb Serial CMOS EEPROM (Electrically Erasable Programmable Read-Only Memory) device from ON Semiconductor. It is designed to provide a robust storage solution for complex electronic systems. This memory module utilizes the popular I²C (Inter-Integrated Circuit) interface, ensuring compatibility with a vast array of microcontrollers and processors.

With a memory size of 64 kilobits, the CAT24S64C4ATR is organized as 8192 words of 8 bits each. It is capable of both random and sequential read and write operations, making it extremely versatile for a wide range of applications. The device operates across a voltage range of 1.7V to 5.5V, which allows it to be used in both low-power and standard applications, and is particularly suitable for battery-operated devices.

One of the key features of the CAT24S64C4ATR is its hardware write protection. This feature includes a write protect pin (WP) that, when connected to VCC, will lock the entire memory, preventing accidental or malicious alterations to the data stored within. This is crucial for applications where data integrity is paramount.

The EEPROM is also designed with a 100-year data retention capability and support for 1 million write cycles, ensuring the reliability and longevity of the data stored. These characteristics make it an ideal choice for critical and long-term data storage applications such as configuration settings, calibration data, and device identity information.

ON Semiconductor has packaged the CAT24S64C4ATR in an 8-lead TSSOP (Thin Shrink Small Outline Package), which is optimized for space-constrained applications. The compact form factor allows designers to incorporate this memory module into designs where board space is at a premium, without sacrificing performance or capacity.

In summary, the CAT24S64C4ATR from ON Semiconductor is a versatile and reliable EEPROM solution that offers a wealth of features for secure data storage. Its broad voltage range, hardware write protection, and small package make it an excellent choice for a variety of applications that require non-volatile memory storage.
