AT88SC0808CA-SH

Specialized ICS Overview

The AT88SC0808CA-SH is a secure memory IC from the CryptoMemory family, manufactured by Microchip Technology. It provides 8-Kbit (1-Kbyte) of EEPROM user memory organized into eight 128-byte zones. The device supports low voltage operation between 2.7V and 3.6V with an operating temperature range of -40°C to +85°C. It features a synchronous 2-wire serial interface compatible at 1.0MHz and includes hardware cryptographic engines for mutual authentication and stream encryption. The component is housed in an 8-SOIC package.

Specialized ICS Feature Summary

• 8-Kbit EEPROM user memory divided into eight individually configurable 128-byte zones
• Hardware cryptographic engine supporting 64-bit mutual authentication and stream encryption
• Synchronous 2-wire serial interface (TWI) with 1.0MHz clock compatibility
• Anti-tearing function and write lock capabilities for data integrity protection

Specialized ICS Applications

• Embedded system authentication
• Smart card applications
• Secure storage for sensitive system information

Specialized ICS Procurement Notes

Verify that the specific ordering suffix SH corresponds to the 8-lead SOIC package configuration. Confirm the supply voltage requirements align with the 2.7V to 3.6V operational range specified in the datasheet. Ensure handling procedures account for the moisture sensitivity level indicated in the product documentation.

Specialized ICS Selection Notes

Select this component when 8-Kbit of secure nonvolatile storage is required within an 8-SOIC footprint. It is suitable for designs needing hardware-based encryption without a microprocessor. Verify that the host controller supports the synchronous 2-wire protocol or ISO 7816 asynchronous T=0 mode as needed.

Specialized ICS Part Context

This part belongs to the Atmel/Microchip CryptoMemory family, which integrates security features directly into EEPROM devices. The AT88SC0808CA variant specifically offers 8-Kbit capacity, distinguishing it from smaller 1-Kbit or 2-Kbit members of the same series while maintaining identical pin configurations across standard packages.

Specialized ICS Replacement Considerations

Direct replacements must match the 8-SOIC package and 8-Kbit secure memory specifications. Verify compatibility with the 2.7V–3.6V supply range and 1.0MHz interface speed. Cross-reference pinouts to ensure alignment with existing PCB layouts.
