AT88SC0204CA-MJ

Specialized ICS Overview

The AT88SC0204CA-MJ is a secure memory module from the CryptoMemory family, providing 2-Kbit (256-byte) EEPROM user storage. It features four independent 64-byte zones with programmable access rights and a 2-Kbit configuration zone for security parameters. The device supports ISO 7816-3 asynchronous T=0 protocol and synchronous 2-wire serial interface (TWI). Operating voltage ranges from 2.7V to 5.5V, with an operating temperature range of 0°C to 70°C. Security features include 64-bit mutual authentication, stream encryption, anti-tearing protection, and voltage/frequency monitors.

Specialized ICS Feature Summary

• 2-Kbit EEPROM user memory divided into four 64-byte zones
• Supports ISO 7816-3 asynchronous T=0 and synchronous 2-wire protocols
• 64-bit mutual authentication and stream encryption capabilities
• Anti-tearing function and voltage/frequency monitors for data integrity

Specialized ICS Applications

• Smart card applications requiring high security and low cost
• Embedded systems needing secure nonvolatile storage for sensitive information
• Multi-application environments using multiple key sets and passwords

Specialized ICS Procurement Notes

Verify that the M2-J module package matches the required smart card form factor. Confirm the commercial temperature rating (0°C to 70°C) aligns with system requirements. Ensure the ordering suffix MJ corresponds to the Tape and Reel delivery format if applicable. Check for compatibility with existing ISO 7816 readers or microcontroller interfaces.

Specialized ICS Selection Notes

Select this model for applications requiring 2-Kbit secure storage with ISO 7816 compliance. Consider the M2-J module package for standard smart card slots. Evaluate the need for asynchronous T=0 versus synchronous TWI communication based on host controller capabilities. Verify that the commercial temperature range meets environmental specifications.

Specialized ICS Part Context

The AT88SC0204CA-MJ belongs to the Atmel CryptoMemory series, now under Microchip Technology. It is part of a family ranging from 1-Kbit to 8-Kbit capacities. The M2-J designation indicates an ISO-compliant smart card module package. This component integrates hardware cryptographic engines for secure data handling in embedded and smart card contexts.

Specialized ICS Replacement Considerations

Other models in the AT88SC0204CA family, such as AT88SC0204CA-MP, offer similar functionality but may differ in package markings or specific module variants. Ensure pinout compatibility when substituting between ISO and TWI-only modules within the same capacity class.
