AT88SC0104CA-PU

Specialized ICS Overview

The AT88SC0104CA-PU is a secure memory device from the CryptoMemory family, providing 1-Kbit (128-byte) EEPROM user storage. It features four independent 32-byte zones with programmable access rights and a 2-Kbit configuration zone for security parameters. The chip supports ISO 7816-3 asynchronous T=0 protocol and synchronous 2-wire serial interface (TWI). Operating voltage ranges from 2.7V to 3.6V, with input pins compatible up to 5.5V. Security includes 64-bit mutual authentication, stream encryption, and cryptographic Message Authentication Codes (MAC).

Specialized ICS Feature Summary

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

Specialized ICS Applications

• Smart card identification and authentication modules.
• Embedded system secure storage for sensitive keys or passwords.
• Access control systems requiring tamper-resistant data storage.

Specialized ICS Procurement Notes

Verify that the specific application requires the 2.7V to 3.6V operating voltage range specified for this part. Confirm compatibility with either the asynchronous T=0 smart card interface or the synchronous 2-wire serial interface, as protocol selection is determined by the power-up sequence. Ensure the host system can support the required initialization timing for the selected communication mode.

Specialized ICS Selection Notes

Select this component when a small, secure non-volatile memory footprint is needed alongside hardware-based authentication capabilities. The 8-PDIP package is suitable for through-hole mounting in industrial environments (-40°C to +85°C). Consider alternative packages such as SOIC or TSSOP if surface-mount technology is required for the design.

Specialized ICS Part Context

This device belongs to the Atmel Microchip CryptoMemory series, which integrates security features directly into EEPROM structures. It serves as a cost-effective alternative to microprocessor-based smart cards for applications requiring basic cryptographic operations without complex operating systems.

Specialized ICS Replacement Considerations

Devices within the same CryptoMemory family, such as the AT88SC0204CA or AT88SC0404CA, offer larger memory capacities but maintain pin compatibility. Verify that the increased memory size does not conflict with existing address mapping or software constraints before substitution.
