AT83C23OK203-RATUM is a programmable crypto controller which provides authentication for contactless smartcards. It is classified as an interface-specialized control device, designed to increase security and improve compatibility when communicating with a contactless card. The device has a wide range of applications, and it is used in automotive, payment, and government security applications, among others.

The device is based on a 4-wire SPI protocol, which makes it simpler and more flexible compared to other application-specialized crypto controllers. It is designed to securely transfer data between two systems, such as a smartcard reader and a contactless card. The device can handle up to 64 keys, making it suitable for authentication applications that require a high level of security.

AT83C23OK203-RATUM is based on an 8051 microcontroller and features a unique on-board crypto engine, allowing it to securely authenticate contactless cards. It also supports a variety of encryption algorithms, including DES, 3DES and AES, making secure data transfers possible. The device also allows for the remote management of keys, enabling an administrator to add new keys or disable existing ones without the need for physical access to the device.

The device is also equipped with an additional 32-bit cryptoprocessor, providing an additional layer of security. It is also designed to remain active even when power is momentarily lost, meaning that the device can continue to authenticate contactless cards even during power surges or system errors.

The device is designed to work with a variety of contactless media, including cards, key fobs and even smartwatches. It is also backwards compatible with older versions of contactless media, including Mifare, iClass and OMNIKEY cards. This makes the device perfect for applications that require a limited number of card formats.

AT83C23OK203-RATUM is an ideal solution for secure authentication needs. It is a cost-effective and easy-to-use device that provides reliable security for contactless cards. Its unique features make it suitable for a wide range of applications, from government security to automotive applications.
