STMicroelectronics 24C64 EEPROM
The 24C64 is a 64 Kbit Electrically Erasable Programmable Read-Only Memory (EEPROM) module from the renowned semiconductor manufacturer STMicroelectronics. This memory device is part of the 24Cxx series, which is well-known for its high reliability, low power consumption, and the flexibility of non-volatile data storage. The 24C64 is designed to provide an efficient storage solution for a wide range of applications that require data to be stored and retrieved even after the power has been turned off.
The device operates across a voltage range of 2.5V to 5.5V, making it suitable for various electronic circuits and products. It offers a significant amount of data storage, with a total of 64 kilobits organized as 8,192 bytes of 8 bits each. The 24C64 uses the I²C serial interface for communication, which allows for easy integration into most microcontroller-based systems and supports a maximum clock frequency of 400 kHz (Fast-mode).
One of the key features of the 24C64 is its byte and page write capabilities. Pages are composed of 32 bytes, which can be written in a single write cycle, thus improving the overall write performance for large data transactions. Additionally, the device has a write cycle time of 5 ms, enabling swift data storage and minimal delay in operations.
The 24C64 also includes a hardware write control feature, which is implemented through a Write Protect pin (WP). When activated, this pin ensures that data stored in the device remains safe from inadvertent write operations, thus providing an extra layer of data security.
STMicroelectronics has designed the 24C64 to be robust and versatile, with an endurance of 1 million write cycles per byte and a data retention period of 40 years. This longevity and reliability make it an ideal choice for applications such as personal computers, mobile communication devices, industrial control systems, and medical equipment, where data integrity and persistence are paramount.
Overall, the STMicroelectronics 24C64 EEPROM stands out for its easy integration, reliable data retention, and efficient power management, making it a go-to choice for designers looking for a non-volatile memory solution.
