AT88SC0808CA-TH

Specialized ICS Overview

The AT88SC0808CA-TH is a secure memory IC from the CryptoMemory family, featuring 8-Kbit (1-Kbyte) EEPROM user memory divided into eight 128-byte zones. 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 device utilizes a synchronous 2-wire serial interface (TWI) with a maximum clock frequency of 4 MHz in asynchronous mode or 1 MHz in synchronous mode. Key security features include programmable access rights, mutual authentication protocols, and cryptographic message authentication codes.

Specialized ICS Feature Summary

• 8-Kbit EEPROM user memory organized into eight individually configurable 128-byte zones
• Integrated hardware encryption engine supporting AES, DES/TDES algorithms and stream encryption
• Supports ISO 7816-3 asynchronous T=0 protocol for smart card applications and synchronous 2-wire interface for embedded systems
• High reliability with 100,000 write cycle endurance and 10-year data retention

Specialized ICS Applications

• Smart card modules requiring ISO 7816 compliance
• Embedded system authentication and secure key storage
• IoT terminal identity verification
• Electronic payment module security

Specialized ICS Procurement Notes

Verify component authenticity through official Microchip channels due to the presence of counterfeit risks in the secure IC market. Confirm that the specific ordering suffix corresponds to the required package type and temperature grade. Ensure compatibility with existing design specifications regarding voltage levels and interface protocols before procurement.

Specialized ICS Selection Notes

Select this model when an 8-Kbit secure memory solution with zone-based access control is required. The TSSOP-8 package is suitable for surface-mount applications. Consider the AT88SC0808CA-Y6H-T variant if tape-and-reel packaging is preferred for automated assembly processes. Verify that the host system can support the necessary authentication commands for secure communication.

Specialized ICS Part Context

This component belongs to the Atmel/Microchip CryptoMemory family, designed to provide high-security non-volatile storage without the complexity of a full microprocessor operating system. It serves as a drop-in replacement for standard serial EEPROMs in terms of pin configuration while adding robust cryptographic capabilities for sensitive data protection.

Specialized ICS Replacement Considerations

The AT88SC0808CA-Y6H-T is a confirmed substitute offering identical electrical and functional characteristics but packaged in tape-and-reel format instead of tubes. Both variants share the same core specifications and are interchangeable based on manufacturing assembly requirements.
