AT88SC0808C-MJTG

Specialized ICS Overview

The AT88SC0808C-MJTG is a secure memory module from the CryptoMemory family, providing 8-Kbit (1-Kbyte) EEPROM user memory. It features eight 128-byte zones with programmable access rights and a 2-Kbit configuration zone. 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, encrypted checksums, stream encryption, anti-tearing function, and voltage/frequency monitors.

Specialized ICS Feature Summary

• 8-Kbit EEPROM user memory divided into eight 128-byte zones
• Supports ISO 7816-3 asynchronous T=0 and synchronous 2-wire protocols
• Integrated hardware security: 64-bit mutual authentication and stream encryption
• Anti-tearing function for data integrity during power loss

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 zones and key sets

Specialized ICS Procurement Notes

Verify the ordering code AT88SC0808C-MJTG corresponds to the M2-J Module in TWI mode only. Confirm the commercial temperature grade (0°C to 70°C) matches system requirements. Ensure the package type aligns with the intended smart card reader or embedded interface design.

Specialized ICS Selection Notes

Select this model for applications requiring ISO 7816 compatibility with TWI-only support. Compare against the MJ variant if asynchronous T=0 protocol is needed. Consider the industrial grade (-40°C to 85°C) if wider temperature operation is required.

Specialized ICS Part Context

This component belongs to the Atmel/Microchip CryptoMemory family, which offers secure memory solutions with built-in cryptographic engines. The AT88SC0808C provides a balance of storage capacity and security features for authentication and data protection without requiring a microprocessor operating system.

Specialized ICS Replacement Considerations

The AT88SC0808C-MJ is a compatible alternative that supports both asynchronous T=0 and synchronous 2-wire modes. Verify protocol requirements before substitution, as the MJTG is restricted to TWI mode.
