The DS28E15G+T is a secure, low-power, and versatile memory solution with one-time programmable (OTP) memory. It is a cost effective, low overhead alternative to standard EEPROM devices that is available in a variety of packages ranging from an 8-pin TSOC, a 9-pin TSSOP, and an 8-pin WSON. The DS28E15G+T has a minimum write cycle capability of 10,000 times, and it can be accessed through a variety of standard communications including I2C, SMBus, and a one-time programmable (OTP) protocol. This makes the DS28E15G+T an ideal solution for a wide range of applications.

The most common applications for the DS28E15G+T are for securely storing key information, such as passwords and cryptographic keys. These keys can be programmed into the device and locked, making them difficult to reverse engineer or brute force. The device can also be used for data logging, as the OTP memory can be read from and written to multiple times, making it useful for storing data over a period of time. Additionally, the DS28E15G+T can be used for firmware storage, allowing for easy updating and maintenance of firmware with the OTP memory.

In terms of its working principle, the DS28E15G+T is simple and straightforward to use. It operates using the I2C, SMBus, and OTP bus protocols, with the OTP bus being used for writing or reading data from the device. When a write command is initiated, the data is transmitted over the data bus to the device, and the device will program the desired data into the memory. Once the data is programmed, it is locked and can no longer be modified. Reading data from the device is also simple, as the data is sent over the data bus and can be read in one byte increments. The device also provides a secure comparison feature, where the host application can issue a read command, and the device will compare the data stored in memory to the data provided by the host application.

Overall, the DS28E15G+T is an ideal solution for a wide range of applications requiring secure memory storage. Its wide range of packages, ease of use, and secure comparison feature make it an ideal choice for applications requiring secure key storage, data logging, or firmware storage. With its low power consumption, versatile programming options, and low cost, the DS28E15G+T is a great solution for any memory application.
