AT88SC0204CA-MPTG

Specialized ICS Overview

The AT88SC0204CA-MPTG is a secure memory device from the CryptoMemory family, providing 2-Kbit (256-byte) EEPROM user memory organized into four 64-byte zones. It operates within a supply voltage range of 2.7V to 3.6V and supports asynchronous ISO 7816-3 T=0 protocol and synchronous 2-wire serial interface (TWI). The device integrates hardware cryptographic features including 64-bit mutual authentication, stream encryption, and Message Authentication Codes (MAC). It includes an anti-tearing function for data integrity during power loss and offers programmable access rights per zone.

Specialized ICS Feature Summary

• 2-Kbit EEPROM user memory divided into four independently configurable 64-byte zones
• Supports asynchronous T=0 smart card protocol and synchronous 2-wire serial interface (TWI)
• Integrated security engine with 64-bit mutual authentication, MAC, and stream encryption
• Anti-tearing function ensures data recovery after unexpected power loss during write cycles

Specialized ICS Applications

• Smart card modules requiring ISO 7816 compliance
• Embedded systems needing secure nonvolatile storage for sensitive keys
• Multi-application environments utilizing multiple key sets and passwords

Specialized ICS Procurement Notes

Verify that the MPTG suffix corresponds to the M2-P module package in TWI mode only. Confirm the operating temperature range matches industrial specifications (-40°C to +85°C) if required by the application environment. Ensure the host system provides a stable 2.7V to 3.6V supply voltage compatible with the specified logic levels.

Specialized ICS Selection Notes

Select this component when a 2-Kbit secure memory footprint is required with support for both smart card and embedded interfaces. The MPTG variant is suitable for applications requiring the specific M2-P module form factor with TWI communication. Consider the anti-tearing feature if data integrity during power interruptions is critical for the system design.

Specialized ICS Part Context

This part belongs to the AT88SC0204CA series, which shares architectural similarities with other capacities in the CryptoMemory family ranging from 1-Kbit to 8-Kbit. The MPTG designation specifically identifies the M2-P module package configured for TWI operation, distinguishing it from ISO-only or standard plastic package variants.

Specialized ICS Replacement Considerations

Compatible substitutes include other AT88SC0204CA variants such as MJTG for ISO/TWI modes or SH/TH packages for surface mount integration, provided the mechanical module constraints are not strict requirements.
