The 24LC64-I/ST is a small EEPROM that serves as temporary storage and working memory for various data storage needs. This chip is especially useful for applications where space is at a premium, such as with embedded systems, or when large amounts of data must be stored with minimal power consumption.

Application Field

The 24LC64-I/ST is well-suited for applications that must save non-volatile data for a long period of time. It is particularly useful for use in embedded systems, industrial control systems, and wearable electronics. The chip can also handle large amounts of data, as it has a 64-word memory size.

The chip also has an excellent power consumption profile, as it can maintain a single operation power supply of up to 5.5V. This makes it well-suited for mobile applications that need to save or retrieve data while still conserving power.

Memory

The 24LC64-I/ST features random access read/write memory. It can store up to 64 words of 8 bits each, or 512 bytes of data. This makes it well-suited for storing sensor information, digital identifiers, or other data that needs to be stored for a long period of time.

The memory is also non-volatile, meaning that it can retain stored data even when power is no longer present. This allows systems to recover after a power loss or off-pocketing, while still remembering the data points or identifiers it had previously stored.

Working Principle

The 24LC64-I/ST operates using a serial interface protocol. Data is sent via the I2C bus interface in 8-bit words, with the first 7 bits representing the data to be stored, and the eighth bit determining whether the data is to be written to or read from the chip.

Once the data is received, the chip carries out the requested action automatically. For read requests, the data is returned in the same format it was sent, with the first 7 bits representing the data, and the eighth bit determining whether the data had been successfully read.

A write request stores the data in the chip\'s memory, with the data being written to a specific memory cell in non-volatile memory, allowing it to be accessed again in the future. Writing data can take up to 5ms to complete, depending on the length and frequency of data being sent.

Conclusion

The 24LC64-I/ST is a low-power, non-volatile memory chip that is ideal for use in embedded systems, handheld devices, and wearables. It features a 64-word random access memory, which can store up to 512 bytes of data. It also features an I2C interface, which allows data to be sent and received serially. This makes it well-suited for applications that require low power consumption, small size, and storage of large amounts of data.
