AT25DN512C-MAHFGP-T is a high-density, electrically erasable, non-volatile write once memory (EEPROM) manufactured by Atmel. The AT25DN512C-MAHFGP-T offers a serialized two-wire solution compatible with I2C bus. This chip is typically used in applications that require reliable storage of sensitive data such as medical applications, automotive applications, and commercial or consumer applications that require secure storage of data.

Application Field

The AT25DN512C-MAHFGP-T is an ideal memory solution for applications with tight space constraints and/or low power requirements. This chip is commonly used in automotive, medical, consumer and commercial applications that need data storage and privacy. For example, in automobiles, the AT25DN512C-MAHFGP-T is used to store critical ECU (engine control unit) and safety data, as well as detect tampering. In medical devices, it is used to store patient records and health-related information. In consumer and commercial applications, the chip is used to securely store user authentication data, credit and debit card information, digital rights management (DRM) keys, and software licenses.

Working Principle

The AT25DN512C-MAHFGP-T is a 5V-only device with 512 Kbits of non-volatile memory (EEPROM) memory cells and an I2C compatible serial interface. This chip features a low write current of 350 microamps and provides full byte, page and block write capabilities. The device is organized as 8192 pages of 16 bytes. Each page can be programmed separately and has its own write protection. The device has three levels of write protection, which consist of a write protect pin, a page write protection, and a global write protection.

The AT25DN512C-MAHFGP-T features a securitylock command, which when enabled disables write, erase, and programming functions. This feature is ideal for embedded applications where the data stored in the chip must be secure from tampering or accidents. The chip also supports a low current standby mode (< 1mW) and an optional hardware reset pin for system resetting, improving power efficiency and system reliability. This device is available in a WSSOP-8, DIL-8 and SOIC-8 package.

The AT25DN512C-MAHFGP-T is a versatile memory solution for applications that require reliable storage of sensitive data and security. This chip provides a cost-effective, reliable and secure solution for a wide range of applications.
