AT88SC0404CA-SH

Specialized ICS Overview

The AT88SC0404CA-SH is a secure memory IC from the CryptoMemory family, providing 4-Kbit (512-byte) EEPROM user memory divided into four 128-byte zones. It operates within a supply voltage range of 2.7V to 3.6V and supports asynchronous ISO 7816-3 T=0 protocol and synchronous 2-wire serial interface (TWI). The device features a 1.0MHz clock frequency compatibility for fast operation and includes high security mechanisms such as 64-bit mutual authentication, cryptographic MACs, stream encryption, and anti-tearing functions. It is housed in an 8-lead SOIC package.

Specialized ICS Feature Summary

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

Specialized ICS Applications

• Smart card applications requiring ISO 7816 compliance
• 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 specific ordering suffix -SH corresponds to the 8-lead SOIC package configuration. Confirm the operating temperature range matches the industrial specification (-40°C to +85°C) required for the application environment. Ensure the host system provides a stable 2.7V to 3.6V supply voltage compatible with the device's electrical characteristics.

Specialized ICS Selection Notes

Select this component when 4-Kbit capacity is sufficient and zone-based access control is required. The choice between asynchronous smart card mode and synchronous embedded mode depends on the host interface capabilities; note that protocol selection occurs at power-up. Consider the 8-lead SOIC package dimensions if PCB space constraints align with the 8S1 footprint specifications.

Specialized ICS Part Context

This part belongs to the Atmel CryptoMemory family, which offers scalable secure memory solutions ranging from 1-Kbit to 8-Kbits. The AT88SC0404CA shares pin configurations with standard serial EEPROMs like the AT24CXXX series in SOIC packages, facilitating easier integration into existing designs while adding cryptographic capabilities.

Specialized ICS Replacement Considerations

Devices within the same AT88SC family, such as the AT88SC0204 or AT88SC0808, offer different memory capacities but maintain similar architectural features. Verify pin compatibility and software command set alignment before substituting with other members of the CryptoMemory series.
