AT88SC0104C-MJTG

Specialized ICS Overview

The AT88SC0104C-MJTG is a secure memory module from the CryptoMemory family, providing 1-Kbit (128-byte) EEPROM user memory. It operates within a voltage range of 2.7V to 5.5V and supports an asynchronous T=0 protocol or a synchronous 2-wire serial interface with a maximum clock frequency of 1 MHz. The device features four individually configurable 32-byte user zones protected by mutual authentication and encryption. It includes a 2-Kbit configuration zone for security parameters and is housed in an M2 J Smart Card Module package.

Specialized ICS Feature Summary

• 1-Kbit EEPROM user memory divided into four 32-byte zones with programmable access rights
• Supports ISO 7816-3 asynchronous T=0 protocol and synchronous 2-wire serial interface
• Integrated cryptographic engine for 64-bit mutual authentication and stream encryption
• Includes anti-tearing function, write lock capabilities, and voltage/frequency monitors

Specialized ICS Applications

• Smart card applications requiring secure data storage and identity authentication
• Embedded systems needing tamper-resistant storage for sensitive keys
• Multi-application environments utilizing multiple key sets and passwords

Specialized ICS Procurement Notes

Verify that the M2 J module variant specifically supports the required communication protocol, as the device supports both asynchronous T=0 and synchronous 2-wire modes. Confirm that the power supply meets the 2.7V to 5.5V operating range. Ensure the system design accounts for the specific physical dimensions of the M2 module form factor during integration.

Specialized ICS Selection Notes

Select this component when a secure, non-volatile storage solution with hardware-level authentication is required for smart card or embedded interfaces. The M2 J package is suitable for contact-based smart card readers. Consider the 1-Kbit capacity limit and the necessity for personalization via the configuration zone before deployment.

Specialized ICS Part Context

This part belongs to the AT88SC0104C series within the CryptoMemory family, which offers scalable secure memory solutions ranging from 1-Kbit to 256-Kbit. The -MJTG suffix denotes the M2 J Smart Card Module package type with tape and reel packaging, distinguishing it from standard plastic packages like SOIC or PDIP.

Specialized ICS Replacement Considerations

Other members of the AT88SC0104C family, such as AT88SC0104C-MP, offer identical functionality but differ in module branding or packaging format. Verify pin compatibility and protocol support when substituting with other secure memory ICs.
