AT88SC0204CA-PU

Specialized ICS Overview

The AT88SC0204CA is a secure memory device from the CryptoMemory family, providing 2-Kbit (256-byte) EEPROM user memory. It features four independent 64-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 a synchronous 2-wire serial interface operating up to 1.0MHz. Electrical specifications include a supply voltage range of 2.7V to 3.6V, an operating temperature range of -40°C to +85°C, and a maximum supply current of 5mA.

Specialized ICS Feature Summary

• Four 512-bit user zones with individually programmable access rights
• 64-bit mutual authentication protocol and stream encryption capabilities
• Supports ISO 7816-3 asynchronous T=0 and synchronous 2-wire serial interfaces
• Anti-tearing function and voltage/frequency monitors for data integrity

Specialized ICS Applications

• Embedded systems requiring secure nonvolatile storage
• Smart card applications compatible with ISO 7816 readers
• Device authentication and identity verification

Specialized ICS Procurement Notes

Verify that the specific order corresponds to the industrial temperature grade (-40°C to +85°C) and the 8-PDIP package type. Confirm the presence of the 'PU' suffix in the part number to ensure compliance with green manufacturing standards exceeding RoHS requirements. Check datasheet revisions for any updates to personalization procedures or fuse blowing sequences.

Specialized ICS Selection Notes

Select this component when 2-Kbit of secure storage is required alongside hardware-based cryptographic features. Ensure the host system can support either the asynchronous smart card interface or the synchronous 2-wire interface, as protocol selection is determined at power-up. Verify that the application environment operates within the specified 2.7V to 3.6V voltage range and does not exceed the 1.0MHz clock frequency limit for synchronous operations.

Specialized ICS Part Context

This device belongs to the Atmel CryptoMemory family, which integrates high-performance secure memory with advanced cryptographic engines. The AT88SC0204CA specifically offers 2-Kbit capacity, distinguishing it from other family members like the 1-Kbit AT88SC0104C or the 8-Kbit AT88SC0808C. It maintains pin compatibility with standard serial EEPROMs in SOIC and PDIP packages to facilitate design transitions.

Specialized ICS Replacement Considerations

Direct replacements must match the 2-Kbit capacity, 8-PDIP package, and industrial temperature range. Verify that alternative secure memory devices support the same 64-bit mutual authentication protocol and 2-wire interface timing characteristics to ensure firmware compatibility.
