AT88SC0404C-MJTG

Specialized ICS Overview

The AT88SC0404C-MJTG is a secure memory IC from the CryptoMemory family, featuring 4-Kbit (512-byte) EEPROM user memory. It operates within a voltage range of 2.7V to 5.5V and supports an operating temperature range of -40°C to +85°C. The device integrates four 128-byte user zones with programmable access rights, a 2-Kbit configuration zone, and a cryptographic engine for mutual authentication and stream encryption. It utilizes a synchronous 2-wire serial interface (TWI) compatible with ISO 7816-2 modules.

Specialized ICS Feature Summary

• 4-Kbit EEPROM user memory divided into four individually configurable 128-byte zones
• Integrated cryptographic engine supporting 64-bit mutual authentication and stream encryption
• Synchronous 2-wire serial interface (TWI) with 1.0MHz compatibility
• ISO 7816-2 compliant M2-J Smart Card Module package

Specialized ICS Applications

• Smart card applications requiring high security without microprocessor OS
• Embedded systems needing secure nonvolatile storage for sensitive information
• Multi-application environments utilizing multiple zones and key sets

Specialized ICS Procurement Notes

Verify that the M2-J module package aligns with the host reader's contact specifications. Confirm that the system power supply remains within the 2.7V to 5.5V operational range. Ensure the communication protocol is configured for synchronous 2-wire mode, as this module variant does not support asynchronous T=0 initialization sequences.

Specialized ICS Selection Notes

Select this component when ISO 7816-2 form factor compliance is required alongside TWI interface capabilities. The M2-J package distinguishes it from standard plastic packages or M2-P modules. Consider the 4-Kbit capacity and four-zone architecture if distinct data files with varying security levels are necessary within the application.

Specialized ICS Part Context

This part belongs to the AT88SC0404C series within the CryptoMemory family. The MJTG suffix specifically denotes the M2-J Smart Card Module package in cut tape format. It shares architectural features with other family members but is distinguished by its specific physical module form factor and interface configuration.
