Placed in the category of Memory, the AT24C164-10SC is a type of integrated circuit chip (IC) that is widely used in many applications today, such as EEPROM and real-time clock (RTC) systems. This article will provide an overview of the AT24C164-10SC application field and working principle, to help readers better understand its function and function.

The AT24C164-10SC is a low-power serial CMOS EEPROM that provides 16,448-bits of memory. It is designed to provide a large memory capacity and long data retention times while requiring minimal board space. The device is available in an 8-pin SOIC surface mount package. It also comes with an integrated 8-bit protocol that allows for fast communication with a variety of microcontrollers, including the ATmega8, as well as the ATmega168. It also supports two-wire (SDA and SCL) serial communication, making it easy to interface to many popular microcontroller platforms.

The AT24C164-10SC is commonly used in a wide range of applications, including embedded systems, industrial, process control, and real-time clocks (RTC). It is particularly suitable for low-power, high-density applications in which data must be retained over long periods of time. In addition, the device is suitable for applications where a large amount of data must be stored and retrieved, such as medical instrumentation, or where data must be stored in a secure manner for later retrieval.

The AT24C164-10SC operates on a two-wire protocol that requires two communication lines: serial data line (SDA) and serial clock line (SCL). The SCL line is an independent clock signal used to synchronize bi-directional data transmission between the host and device. The SDA line is bidirectional and is used to send and receive data. Both lines operate at a nominal frequency of 400kHz. The device can be put into a low-power mode by pulling the SDA line low. This allows the system to reduce power consumption when data is not being actively transmitted.

At the operational level, the AT24C164-10SC supports read, write, and erase operations. The device supports both random-access reads and writes, allowing for the storage and retrieval of data without prior knowledge of the stored data structure. It also supports an erase command, which erases the entire memory or block of memory. The erase command ensures that prior data will not remain stored in the memory after the write command is issued. It also reduces the amount of time required to complete a read or write operation.

The AT24C164-10SC utilizes a form of error detection and correction (EDC) known as cyclic redundancy check (CRC). This EDC technique allows the device to detect and correct certain errors in the data transferred over the communication lines. The EDC also helps to ensure that when data is read back, it is the same as when it was written. This is especially useful in applications where data integrity is paramount, such as medical instrumentation.

In summary, the AT24C164-10SC is a low-power CMOS EEPROM chip used in a variety of applications, including those that require long data retention times or the secure storage of data. It uses a two-wire protocol to send and receive data from the host system, and supports both random-access reads and writes. The chip also incorporates error detection and correction to ensure that data is accurately transmitted and read back. This makes it an ideal choice for a variety of applications.
