AT88SC0404CA-SU

Specialized ICS Overview

The AT88SC0404CA-SU is a secure memory integrated circuit from the CryptoMemory family, featuring 4-Kbit (512-byte) EEPROM user memory. It operates within a supply voltage range of 2.7V to 3.6V and supports a synchronous 2-wire serial interface with clock frequencies up to 1.0MHz. The device includes four individually configurable 1-Kbit zones, a 2-Kbit configuration zone, and hardware cryptographic engines for mutual authentication and stream encryption. It is housed in an 8-lead SOIC package.

Specialized ICS Feature Summary

• 4-Kbit EEPROM user memory divided into four 1-Kbit zones with programmable access rights
• Hardware cryptographic engine supporting 64-bit mutual authentication and stream encryption
• Synchronous 2-wire serial interface compatible with standard I2C-like protocols
• Anti-tearing function and write lock capabilities for data integrity protection

Specialized ICS Applications

• Embedded systems requiring secure nonvolatile storage for sensitive information
• Smart card modules utilizing ISO 7816 Class B operation
• Authentication ICs for multi-application environments with multiple key sets

Specialized ICS Procurement Notes

Verify that the specific suffix 'SU' corresponds to the 8-lead SOIC package variant as documented in the ordering information. Confirm the industrial temperature grade (-40°C to +85°C) matches the application requirements. Ensure the device personalization process, including fuse blowing, is completed by authorized personnel before deployment.

Specialized ICS Selection Notes

Select this component when a 4-Kbit secure memory solution with hardware-based encryption is required. It is suitable for applications needing fast initialization via synchronous mode or smart card compatibility via asynchronous T=0 protocol. Consider the 8-lead SOIC package constraints regarding board space and thermal performance during selection.

Specialized ICS Part Context

This part belongs to the Atmel CryptoMemory family, designed to provide high-security storage without a microprocessor operating system. It shares pin configurations with standard serial EEPROMs like the AT24CXXX series to facilitate easier integration into existing designs while adding robust security features.
