AT88SC0404CA-MP

Specialized ICS Overview

The AT88SC0404CA-MP is a secure memory device from the CryptoMemory family, providing 4-Kbit (512-byte) EEPROM user memory divided into four 128-byte zones. It supports ISO 7816 Class B (3V) asynchronous T=0 protocol and synchronous 2-wire serial interface (TWI). Operating voltage ranges from 2.7V to 3.6V with input compatibility up to 5.5V. The device integrates a 64-bit mutual authentication protocol, stream encryption, and cryptographic Message Authentication Codes (MAC). It features anti-tearing protection, voltage/frequency monitors, and programmable access rights for each zone.

Specialized ICS Feature Summary

• 4-Kbit EEPROM user memory organized into four independent 128-byte zones
• Supports ISO 7816-3 asynchronous T=0 protocol and synchronous 2-wire serial interface
• Integrated 64-bit dynamic symmetric mutual authentication and stream encryption
• Anti-tearing function ensures data integrity during power loss events

Specialized ICS Applications

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

Specialized ICS Procurement Notes

Verify that the M2-P module package matches the specific smart card reader or host interface requirements. Confirm that the system operates within the 2.7V to 3.6V supply range. Ensure proper personalization of configuration memory and blowing of security fuses before deployment to lock access rights and keys.

Specialized ICS Selection Notes

Select this model for applications requiring ISO 7816 Class B compliance or fast 2-wire serial communication. Choose based on the need for four distinct security zones and the requirement for hardware-based encryption without a microprocessor operating system. Verify pin compatibility if replacing standard EEPROMs, as it shares pin configurations with AT24CXXX devices in plastic packages.

Specialized ICS Part Context

The AT88SC0404CA belongs to the Atmel CryptoMemory series, which provides secure memory solutions with embedded cryptographic engines. This specific part offers 4-Kbit capacity, distinguishing it from 1-Kbit and 8-Kbit variants in the family. It is designed for both smart card and embedded applications, offering flexibility through dual protocol support.

Specialized ICS Replacement Considerations

Direct replacements include other AT88SC0404CA variants such as AT88SC0404CA-MJ or AT88SC0404CA-SH-T, depending on required packaging (Module vs. SOIC/TSSOP). Ensure the substitute supports the same voltage range and protocol modes (T=0 or TWI) as the original design.
