AT88SC0104C-SI

Specialized ICS Overview

The AT88SC0104C-SI is a secure memory device from the CryptoMemory family, providing 1 Kbit (128-byte) of EEPROM user memory. It features four individually configurable 32-byte zones and a 2-Kbit configuration zone for keys and passwords. The component supports ISO 7816 Class A/B smart card operations via asynchronous T=0 protocol and embedded applications using a synchronous 2-wire serial interface at 1.5 MHz. Operating voltage ranges from 2.7V to 5.5V, with an industrial temperature range of -40°C to +85°C. It includes high-security features such as mutual authentication, stream encryption, anti-tearing, and tamper detection.

Specialized ICS Feature Summary

• 1-Kbit User Memory: Four 32-byte zones with programmable access rights.
• High Security: 64-bit dynamic symmetric mutual authentication and stream encryption.
• Dual Protocol Support: ISO 7816-3 Asynchronous T=0 and Synchronous 2-wire Serial Interface.
• Tamper Protection: Anti-tearing function, voltage/frequency monitors, and modify-forbidden modes.

Specialized ICS Applications

• Smart Card Applications
• Embedded Secure Storage

Specialized ICS Procurement Notes

Verify the ordering code AT88SC0104C-SI corresponds to the 8-lead SOIC package in the Industrial temperature grade (-40°C to +85°C). Confirm that the specific revision matches the required datasheet version, as Atmel/Microchip may update documentation without changing the part number suffix. Ensure compatibility with the host system's voltage levels (2.7V–5.5V) and interface requirements.

Specialized ICS Selection Notes

Select this component when 1 Kbit of secure nonvolatile storage is required with hardware-level cryptographic protection. It is suitable for systems needing ISO 7816 compliance or fast 2-wire serial communication. Consider the 8-lead SOIC package for surface-mount assembly. Evaluate if the built-in security features (authentication, encryption) meet the application's data integrity needs compared to standard EEPROMs.

Specialized ICS Part Context

The AT88SC0104C belongs to the CryptoMemory family, which offers scalable secure memory solutions from 1 Kbit to 1 Mbit. The 'SI' suffix denotes the Industrial temperature grade and 8-lead SOIC package. This series integrates a cryptographic engine directly into the EEPROM structure, allowing for secure key storage and authenticated data exchange without external microprocessors.

Specialized ICS Replacement Considerations

Direct replacements within the same package and pinout include other members of the CryptoMemory family such as the AT88SC0204C, AT88SC0404C, or AT88SC0808C, provided the memory capacity meets the design requirements. Verify that the replacement part supports the same voltage range and security protocols.
