AT88SC0204CA-SH

Specialized ICS Overview

The AT88SC0204CA-SH is a secure memory device from the CryptoMemory family, manufactured by Microchip Technology. It provides 2-Kbit (256-byte) EEPROM user memory organized into four independent 64-byte zones. The component integrates hardware cryptographic features including a 64-bit mutual authentication protocol and stream encryption. It supports dual communication protocols: asynchronous T=0 for smart card applications and synchronous 2-wire serial interface for embedded systems. Operating voltage ranges from 2.7V to 3.6V, with input pins compatible up to 5.5V. The device is housed in an 8-lead SOIC package.

Specialized ICS Feature Summary

• 2-Kbit EEPROM user memory divided into four individually configurable security zones
• Hardware cryptographic engine supporting 64-bit mutual authentication and stream encryption
• Dual-mode operation: ISO 7816-3 asynchronous T=0 protocol and synchronous 2-wire serial interface
• Anti-tearing function for data integrity during power loss events

Specialized ICS Applications

• Smart card identity modules requiring ISO 7816 compliance
• Embedded system authentication and secure key storage
• Access control systems utilizing password verification
• IoT device identification and anti-cloning protection

Specialized ICS Procurement Notes

Verify the ordering suffix SH corresponds to the 8-lead SOIC package in bulk tubes of 100 units. Confirm the industrial temperature grade (-40°C to +85°C) matches application requirements. Ensure personalization equipment supports the specific transport code ($E5 47 47) required for initial configuration before blowing security fuses.

Specialized ICS Selection Notes

Select this model when 2-Kbit capacity is sufficient and both smart card and embedded interfaces are needed. Compare against AT88SC0104C for lower density or AT88SC0404C for higher capacity. Verify that the host system can provide the required 2.7V to 3.6V supply voltage while maintaining 5.5V tolerance on I/O lines.

Specialized ICS Part Context

This component belongs to the Atmel CryptoMemory series, now managed by Microchip Technology following the acquisition of Atmel. The AT88SC0204CA shares pin compatibility with standard AT24CXXX Serial EEPROMs in SOIC packages, facilitating drop-in replacement for non-security applications where physical footprint constraints exist.

Specialized ICS Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Direct replacements must match the 2-Kbit capacity, 8-lead SOIC package, and integrated cryptographic engine specifications.
