The AT25M02-SSHD-B is a type of non-volatile Memory. This product is a 2-Mbit SPI serial electrically erasable programmable read-only memory (EEPROM). Non-volatile memory (NVM) technology used in AT25M02-SSHD-B includes standard SPI 5-byte instruction sequences and carries out operations by following the on-chip protocols. This also accounts for the reliability and safety of the product and makes it a perfect choice for users.

The AT25M02-SSHD-B provides: 2 Mbits of serial electrically erasable and programmable memory, enhanced SPI transfer capabilities, high-speed performance, low-power consumption and a high level of security.

The AT25M02-SSHD-B can be deployed in a range of applications including: handheld devices, automotive systems, medical systems, network protocol development, industrial appliance control and a variety of other embedded systems. It is suitable for a variety of applications, such as user parameter storage, data logging and code storage.

In addition, the device features a asynchronous burst read mode that allows the controller to read data from multiple address locations, providing a high speed data transfer rate. This feature is particularly useful for industrial and automotive applications where data logging and code storage are required. The chip also includes an auxiliary flash layer which is used for storing calibration codes, error correction codes and other specialized data.

The working principle of AT25M02-SSHD-B is simple and efficient. After the power is switched on, the device automatically writes the program into the internal memory and then proceeds to execute it. The device is able to store data in flash memory which is non-volatile. This means that data is not lost when the power is switched off. When a write cycle is initiated, the data is buffered in the write buffer and when it is completed the program is written into the flash memory and the device is ready to execute the next instruction.

The device can be programmed and erased with programming instructions. The instructions are written in a specific format and they are transferred over the SPI bus. The instructions are then parsed by the device and executed accordingly. The erase operation is done in a single step, while the programming is done in four steps and can take up to 100 milliseconds.

The AT25M02-SSHD-B has an excellent endurance of >100k write cycles and boasts data-retention of >100 years. It is important to note that the device includes secure data protection features such as write-protection, read-protection and reprogram-protection. It also provides a reliable power-on reset for industrial and automotive applications.

The AT25M02-SSHD-B is an ideal choice for applications that require enhanced performance and security. The device offers a high-speed performance, low-power consumption and a high level of data protection, making it a perfect choice for critical industrial and automotive applications.
