AT88SC1616C-SU

Specialized ICS Overview

The AT88SC1616C-SU is a 16-Kbit (2-Kbyte) secure EEPROM from the CryptoMemory family, housed in an 8-lead SOIC package. It features sixteen individually configurable 128-byte user zones and a 2-Kbit configuration zone containing secret keys and passwords. The device supports asynchronous ISO 7816-3 T=0 smart card protocols and synchronous 2-wire serial interfaces operating up to 1 MHz. Security mechanisms include a 64-bit mutual authentication protocol, encrypted checksums, stream encryption, anti-tearing protection, and voltage/frequency monitoring. Operating voltage ranges from 2.7V to 5.5V with industrial temperature support.

Specialized ICS Feature Summary

• 16-Kbit EEPROM divided into 16 programmable 128-byte zones with independent access rights
• Integrated hardware cryptographic engine supporting 64-bit dynamic symmetric mutual authentication
• Dual communication modes: Asynchronous ISO 7816-3 T=0 for smart cards and Synchronous 2-wire serial interface
• Security features including anti-tearing data recovery, write lock, and four sets of authentication keys

Specialized ICS Applications

• Smart card applications requiring ISO 7816-3 compliance
• Embedded systems needing secure nonvolatile storage for sensitive information
• Multi-application environments utilizing multiple key sets and password verification

Specialized ICS Procurement Notes

Verify that the specific ordering suffix corresponds to the required package type and temperature range. The datasheet indicates the SH suffix for the 8-lead SOIC industrial grade variant; confirm if the SU suffix represents a valid manufacturer designation or a distributor-specific code. Ensure the component matches the green compliant specifications and verify the revision history for any pinout or functional changes.

Specialized ICS Selection Notes

Select this component when 16-Kbit capacity with granular zone-based security is required. It is suitable for designs needing both smart card reader compatibility and standard I2C-like embedded integration. Consider the anti-tearing feature if power loss during write operations is a risk. Verify that the host system can support the necessary initialization sequences for either the asynchronous or synchronous protocol mode.

Specialized ICS Part Context

The AT88SC1616C belongs to the CryptoMemory series, which provides high-security EEPROM solutions without requiring a microprocessor. This family ranges from 1-Kbit to 256-Kbit densities. The device integrates a cryptographic engine for mutual authentication and encryption, distinguishing it from standard EEPROMs by offering built-in protection against cloning and unauthorized data access.

Specialized ICS Replacement Considerations

The AT88SC1616C-SH is the documented equivalent for the 8-lead SOIC industrial package. Other members of the CryptoMemory family offer different memory densities but share similar architectural features. Verify pin compatibility and protocol support when substituting with other secure memory devices.
