Microchip Technology, Inc. Integrated Circuits (ICs) - Specialized ICs AT88SC0404CA-Y6H-T

The AT88SC0404CA from Win Source Electronics is a secure memory integrated circuit designed for embedded and smart card applications. It features 4-Kbit of EEPROM user memory, organized into four 1-Kbit zones, each with programmable access rights. The device supports a self-timed write cycle and allows for single byte or 16-byte page writes. It includes advanced security features such as a 64-bit mutual authentication protocol, cryptographic Message Authentication Codes (MAC), and stream encryption, making it suitable for storing sensitive information. The AT88SC0404CA operates on a low voltage supply of 2.7V to 3.6V and communicates via a 2-wire serial interface, compatible with speeds up to 1.0MHz. It is housed in an 8-lead plastic package, with a pin configuration that aligns with Atmel's AT24CXXX Serial EEPROM devices. The product is designed for high reliability, offering an endurance of 100,000 write cycles and a data retention period of 10 years, along with ESD protection rated at 2,000V minimum.
