SLE 66R04PNBZZZA1 is a highly integrated IC specialized for smart card and related applications. It is a compact low power chip intended for an extended life cycle, and provides a rich set of features for contactless, contact or dual-interface smart cards. This chip includes hardware components specifically tailored for smart card applications, making it an ideal solution for applications where cost and size are driving factors.

Applications:

• Identity and access cards
• e-purse, prepaid cards
• Loyalty, bonus and membership cards
• Healthcare cards
• Security tokens
• Secure memory tokens

The SLE 66R04PNBZZZA1 offers a high level of integration, functionality and security. In addition to supporting the standard ISO/IEC 7816 component, the SLE 66R04PNBZZZA1 includes the following features:

• Integrated 8-bit microcontroller with 256 bytes of RAM
• Integrated fi eld-programmable Non-volatile Memory (NVM), with up to 4 Kbyte memory capacity
• Integrated AES-128 and DES/3DES encryption
• High security features such as random number generators, secure memory, user authentication and access control bits
• Integrated ESD and RFID features
• Integrated tamper detection circuitry
• Multi-protocol support for ISO/IEC 14443 (A,B) including contactless smart cards and contact-only cards.

Working Principle:

The SLE 66R04PNBZZZA1 relies on a system of hardware-enforced access control and authentication on the card. It employs strong cryptographic algorithms, based on unique hardware-implemented keys, to provide extra layers of security. The card processes requests from the reader, and if requested information or operations are authorized and authenticated by the controller, then the results are returned to the reader. The card also performs self-tests to ensure that it is functioning correctly and to detect any external tampering.

The chip has a built-in instruction interpreter and 32K bytes of EEPROM memory. The memory is divided into four blocks - one block for the program store, one block for the account data, one block for the execution environment, and one block for the security features. It is capable of storing a number of executable commands, each with its own parameters, and a command to lock the card, preventing any further access to the memory. The card also implements multiple layers of access control, so that certain commands can only be executed by specified user types.

The SLE 66R04PNBZZZA1 supports multiple communication protocols for contactless, contact, or dual-interface cards. Additionally, it supports the standard ISO/IEC 7816 protocol, which is used for all card-reader communication. In addition, the chip features RSA 1024, Triple-DES, and AES 128 encryption algorithms, as well as authentication and access control mechanisms.

The SLE 66R04PNBZZZA1 provides a secure platform for applications such as identity and access cards, e-purse and prepaid cards, loyalty, bonus, and membership cards, healthcare cards, secure memory tokens, and security tokens. It offers high levels of integration and security, and is ideal for applications where cost and size are important considerations.
