AT88SC0808CA-SH-T

Specialized ICS Overview

The AT88SC0808CA-SH-T is a secure memory IC from the CryptoMemory® family, manufactured by Microchip Technology. It provides 8-Kbit (1-Kbyte) EEPROM user memory organized into eight 128-byte zones with programmable access rights. The device features a synchronous 2-wire serial interface (TWI) operating up to 1.0MHz and supports ISO 7816-3 asynchronous T=0 protocol for smart card applications. Key security features include 64-bit mutual authentication, stream encryption, cryptographic Message Authentication Codes (MAC), anti-tearing protection, and voltage/frequency monitors. It operates within a supply voltage range of 2.7V to 3.6V and an industrial temperature range of -40°C to +85°C.

Specialized ICS Feature Summary

• 8-Kbit EEPROM user memory divided into eight individually configurable 128-byte zones
• Integrated hardware cryptographic engine supporting 64-bit mutual authentication and stream encryption
• Dual communication modes: Synchronous 2-wire serial interface (up to 1.0MHz) and Asynchronous ISO 7816-3 T=0 protocol
• Advanced security protections including anti-tearing function, write lock, and modify forbidden options

Specialized ICS Applications

• Smart card modules requiring ISO 7816 compliance
• Embedded systems needing secure nonvolatile storage for sensitive data
• Device authentication and identity verification in IoT networks
• Access control systems and electronic payment terminals

Specialized ICS Procurement Notes

Verify that the ordering suffix '-SH-T' corresponds to the 8-lead SOIC package in tape and reel format containing 4,000 units per reel. Confirm the specific voltage range and temperature grade requirements match the Industrial (-40°C to +85°C) specifications provided in the datasheet summary before finalizing procurement orders.

Specialized ICS Selection Notes

Select this component when both high-speed embedded communication via TWI and smart card interoperability via ISO 7816 are required. Ensure the host system can support the 2.7V to 3.6V supply voltage range. Consider the 8-SOIC package dimensions if space constraints exist, noting its pin compatibility with standard AT24CXXX serial EEPROMs for easier integration.

Specialized ICS Part Context

This part belongs to the Atmel/Microchip CryptoMemory® family, which integrates security features directly into EEPROM technology. The AT88SC0808CA variant specifically offers 8-Kbit capacity, distinguishing it from smaller 1-Kbit or larger variants in the series. The 'SH' designation indicates the 8-lead SOIC package, while '-T' denotes the tape and reel delivery method.

Specialized ICS Replacement Considerations

For pin-compatible replacements, consider other members of the AT88SC0808CA family such as AT88SC0808CA-SU (TSSOP) or AT88SC0808CA-PU (PDIP), provided the package type change is acceptable. Verify that any substitute maintains the same 8-Kbit memory size and security feature set.
