Description

The Atmel AT88SC0404C is a high-security, multi-functional storage chip designed to protect sensitive information in authentication, identification, and secure access applications. It provides 4 Kbit (512 bytes) of EEPROM memory, divided into four configurable 128-byte regions, each with unique access permissions and protection levels.

Unlike traditional storage chips that require a microprocessor-based operating system, the AT88SC0404C uses embedded security logic to manage encryption, password authentication, and access control directly on the chip. This architecture simplifies system design while maintaining strong data integrity and confidentiality.

The device supports the ISO/IEC 7816-3 T=0 communication protocol, enabling easy integration with smart cards, terminals, and embedded controllers. It includes encrypted authentication keys, secure read/write permissions, and tamper-proof mechanisms to effectively defend against cloning and unauthorized access.

The AT88SC0404C is a compact, low-power, and highly reliable chip, making it an ideal choice for applications such as bank cards, access control systems, prepaid cards, membership programs, and IoT authentication modules.
