AT88SC0404CA-SH-T

Specialized ICS Overview

The AT88SC0404CA-SH-T is a secure memory IC from the CryptoMemory family, providing 4-Kbit (512-byte) EEPROM user storage. It features four individually configurable 1-Kbit zones and supports ISO 7816-3 asynchronous T=0 protocol alongside a synchronous 2-wire serial interface. Operating within a 2.7V to 3.6V supply range, it integrates hardware encryption for mutual authentication and data integrity. The device utilizes an 8-lead SOIC package in tape-and-reel format.

Specialized ICS Feature Summary

• 4-Kbit EEPROM divided into four 128-byte user-accessible zones
• Supports ISO 7816-3 T=0 asynchronous and 1MHz synchronous 2-wire interfaces
• Hardware-based mutual authentication using 64-bit keys and stream encryption
• Anti-tearing function ensures data recovery during power loss events

Specialized ICS Applications

• Smart card identity modules
• Embedded system key storage
• Secure access control systems

Specialized ICS Procurement Notes

Verify that the specific ordering suffix matches the required communication protocol configuration. Confirm the voltage range aligns with the target application's power supply constraints. Ensure the tape-and-reel quantity meets production requirements without exceeding storage limits.

Specialized ICS Selection Notes

Select this component when both smart card interoperability and embedded serial connectivity are required. Evaluate the need for anti-tearing protection if write operations occur under unstable power conditions. Consider the 8-lead SOIC footprint compatibility with existing PCB layouts.

Specialized ICS Part Context

This part belongs to the AT88SC0404CA series, which shares architectural similarities with other CryptoMemory devices but offers distinct memory density. The SH-T designation indicates the standard SOIC package form factor supplied in reel packaging for automated assembly processes.

Specialized ICS Replacement Considerations

Direct pin-compatible replacements include other members of the AT88SC0404CA family with different package options or voltage ranges. Verify functional equivalence regarding security fuse configurations and command sets before substitution.
