AT88SC0104CA-MJTG

Specialized ICS Overview

The AT88SC0104CA-MJTG is a secure memory device from the CryptoMemory family, featuring 1-Kbit (128-byte) EEPROM user memory. It operates within a supply voltage range of 2.7V to 3.6V and supports an asynchronous T=0 protocol compliant with ISO 7816-3 Class B standards. The device integrates four 256-bit user zones with programmable access rights, a 2-Kbit configuration zone, and hardware cryptographic engines for mutual authentication and stream encryption. It utilizes a synchronous 2-wire serial interface (TWI) compatible with 5V logic levels and functions at clock frequencies up to 1.0MHz.

Specialized ICS Feature Summary

• 1-Kbit EEPROM user memory divided into four individually configurable 256-bit zones
• Hardware cryptographic engine supporting 64-bit mutual authentication and stream encryption
• ISO 7816-3 asynchronous T=0 protocol support for smart card reader interoperability
• Synchronous 2-wire serial interface (TWI) operating up to 1.0MHz with 5V compatibility

Specialized ICS Applications

• Smart card modules requiring secure identity storage and authentication
• Embedded systems needing tamper-resistant nonvolatile data protection
• Access control systems utilizing dynamic symmetric-mutual authentication protocols

Specialized ICS Procurement Notes

Verify that the M2-J module variant specifically supports the required asynchronous T=0 protocol alongside TWI modes. Confirm that the host system provides a stable 2.7V to 3.6V power supply, as exceeding this range may damage the device. Ensure proper handling procedures are followed for the tape and reel packaging format during assembly.

Specialized ICS Selection Notes

Select this component when a compact smart card module form factor is required for ISO 7816 compliance. The M2-J package is suitable for applications needing both asynchronous smart card communication and synchronous embedded bus connectivity. Consider the 1-Kbit capacity limit and the necessity for hardware-based security features over standard EEPROMs.

Specialized ICS Part Context

This part belongs to the AT88SC0104CA series within Microchip's CryptoMemory portfolio. The -MJTG suffix indicates the M2-J Smart Card Module package delivered in Tape & Reel format. It shares architectural similarities with other devices in the 1-Kbit to 8-Kbit memory density range but is distinct in its specific module footprint and delivery method.

Specialized ICS Replacement Considerations

Direct pin-compatible replacements include other AT88SC0104CA variants such as the -MP or -PU packages, provided the application does not strictly require the M2-J module physical dimensions. Higher density models like the AT88SC0204CA offer similar functionality with increased storage.
