AT88SC0104CA-SH-T

Specialized ICS Overview

The AT88SC0104CA-SH-T is a secure memory device from the CryptoMemory family, featuring 1-Kbit (128-byte) EEPROM user memory. It operates within a supply voltage range of 2.7V to 3.6V and supports an industrial temperature range of -40°C to +85°C. The component utilizes a synchronous 2-wire serial interface (TWI) with clock frequencies up to 1.0MHz for embedded applications or asynchronous T=0 protocol for smart card modules. It includes four individually configurable 32-byte user zones protected by cryptographic features such as mutual authentication and stream encryption.

Specialized ICS Feature Summary

• 1-Kbit EEPROM user memory divided into four 32-byte zones with programmable access rights
• Supports ISO 7816-3 asynchronous T=0 protocol and synchronous 2-wire serial interface
• Integrated hardware security engine providing 64-bit mutual authentication and stream encryption
• Anti-tearing function ensures data integrity during power loss events

Specialized ICS Applications

• Embedded system authentication and secure storage
• Smart card modules requiring ISO 7816 compliance
• Access control systems and IoT device identification

Specialized ICS Procurement Notes

Verify that the specific ordering suffix '-SH-T' corresponds to the 8-lead SOIC package in Tape & Reel format containing 4,000 units per reel. Confirm the voltage range specification matches the application requirements, as this variant is rated for 2.7V to 3.6V operation. Ensure compatibility with the host controller's I/O voltage levels, noting the 5.5V input high voltage tolerance on the SDA/IO and SCL pins.

Specialized ICS Selection Notes

Select this model when a 1-Kbit secure storage capacity is required alongside dynamic mutual authentication capabilities. The synchronous 2-wire interface is suitable for microcontroller-based designs needing fast initialization without complex smart card reader interfaces. Consider the anti-tearing feature if the application demands data recovery mechanisms following unexpected power interruptions during write cycles.

Specialized ICS Part Context

This component belongs to the AT88SC0104CA series within the broader CryptoMemory product line. The 'SH' designation indicates the 8-lead Small Outline Integrated Circuit (SOIC) package, while the '-T' suffix specifies the tape and reel delivery method. This part shares architectural similarities with other devices in the family but is distinct in its specific memory density and package configuration.

Specialized ICS Replacement Considerations

Direct replacements must match the 1-Kbit capacity, 8-lead SOIC package, and 2.7V-3.6V operating voltage. Verify that alternative secure memory ICs support the same 2-wire serial interface timing and cryptographic command set to ensure firmware compatibility.
