AT88SC0204C-MJTG

Specialized ICS Overview

The AT88SC0204C-MJTG is a secure memory module from the CryptoMemory family, providing 2-Kbit (256-byte) EEPROM user memory. It features four 64-byte zones with programmable access rights and a 2-Kbit configuration zone containing a 37-byte OTP area and 160-byte key storage. The device supports ISO 7816 Class A/B operation and asynchronous T=0 protocol alongside a synchronous 2-wire serial interface. Operating voltage ranges from 2.7V to 5.5V, with an endurance of 100,000 cycles and data retention exceeding 10 years.

Specialized ICS Feature Summary

• Integrated cryptographic engine supporting 64-bit mutual authentication and stream encryption
• Four independent 64-byte user zones with configurable security levels
• Supports both asynchronous ISO 7816-3 T=0 protocol and synchronous 2-wire serial interface
• Anti-tearing function for data integrity during power loss events

Specialized ICS Applications

• Smart card applications requiring secure identification
• Embedded systems needing tamper-resistant data storage
• Multi-application smart cards utilizing multiple key sets

Specialized ICS Procurement Notes

Verify that the M2-J module package matches the specific contact layout required by the host reader or socket. Confirm whether the application requires the asynchronous T=0 mode or the default synchronous 2-wire mode, as this determines the initialization sequence. Ensure the ordering suffix TG indicates the correct environmental compliance status for the target market.

Specialized ICS Selection Notes

Select this component when a small footprint secure memory solution is needed for smart card form factors. The M2-J module is suitable for applications requiring direct integration into card substrates. Compare against other CryptoMemory sizes if more than 256 bytes of protected storage are required.

Specialized ICS Part Context

This part belongs to the AT88SC0204C series within the broader CryptoMemory family. It shares architectural similarities with other devices in the line but is distinct in its 2-Kbit capacity and M2-J module packaging format designed for ISO 7816 compliant smart card implementations.

Specialized ICS Replacement Considerations

Direct pin-compatible replacements are limited due to the proprietary module form factor. Verify functional equivalence regarding the cryptographic algorithms and communication protocols before substituting with other secure memory modules.
