AT88SC0808C-CI

Specialized ICS Overview

The AT88SC0808C-CI is a secure memory device from the CryptoMemory family, providing 8 Kbits (1 Kbyte) of EEPROM user memory. It features eight 128-byte zones with individually programmable access rights and a 2-Kbit configuration zone for keys and passwords. The chip supports ISO 7816-3 asynchronous T=0 protocol and a synchronous 2-wire serial interface operating up to 1.5 MHz. It operates within a voltage range of 2.7V to 5.5V and an industrial temperature range of -40°C to +85°C. Encased in an 8-LAP (8x5 mm) package, it includes hardware encryption, dynamic mutual authentication, and anti-tearing protection.

Specialized ICS Feature Summary

• 8-Kbit User Memory: Divided into eight 128-byte zones with independent security configurations.
• Dual Interface: Supports ISO 7816-3 asynchronous T=0 protocol and synchronous 2-wire serial communication at 1.5 MHz.
• High Security: Implements 64-bit dynamic symmetric mutual authentication, stream encryption, and encrypted checksums (MAC).
• Reliability: Offers 100,000 write cycle endurance, 10-year data retention, and anti-tearing function for power-loss recovery.

Specialized ICS Applications

• Smart Card Applications: Compatible with standard smart card readers using ISO 7816-3 protocols.
• Embedded Systems: Secure storage for sensitive system information via 2-wire serial interface.
• Multi-application Devices: Utilizes multiple zones and key sets for distinct application isolation.

Specialized ICS Procurement Notes

Verify the specific ordering code AT88SC0808C-CI corresponds to the 8-lead Leadless Array Package (LAP) with industrial temperature rating (-40°C to +85V). Confirm that the supplier provides original Microchip Technology products, as the component was originally developed by Atmel. Ensure compatibility with the 8x5 mm LAP footprint during procurement planning.

Specialized ICS Selection Notes

Select the AT88SC0808C-CI when an industrial temperature range (-40°C to +85°C) is required alongside the compact 8-LAP surface-mount package. Choose this model over the commercial grade variants if the application environment exceeds 70°C. Ensure the design supports either the asynchronous smart card interface or the synchronous 2-wire serial interface, as protocol selection depends on the power-up sequence.

Specialized ICS Part Context

The AT88SC0808C belongs to the CryptoMemory family, which offers scalable secure memory solutions from 1 Kbit to 1 Mbit. This specific model provides 8 Kbits of user memory, positioning it between smaller 1K/2Kbit devices and larger capacity options. It shares the same pinout and basic architecture as other members of the series, allowing for potential capacity upgrades within the same package constraints.

Specialized ICS Replacement Considerations

Direct replacements must match the 8-LAP (8CN1) package and industrial temperature range. Other AT88SC0808C variants like the SI (SOIC) or PI (PDIP) are not pin-compatible due to different package types. Cross-model substitution within the CryptoMemory family requires verifying pinout compatibility and ensuring the replacement part supports the required memory density and security features.
