AT88SC0204C-MJ

Specialized ICS Overview

The AT88SC0204C-MJ is a secure memory device from the CryptoMemory family, manufactured by Microchip Technology. It provides 2-Kbit of EEPROM user memory organized into four zones. The component operates within a voltage range of 2.7V to 5.5V and supports both synchronous 2-Wire serial interface (TWI) and asynchronous ISO 7816-3 T=0 protocols. It features a 64-bit mutual authentication protocol, encrypted checksums, and stream encryption for data protection.

Specialized ICS Feature Summary

• 2-Kbit EEPROM User Memory with four individually configurable security zones
• Integrated hardware cryptographic engine supporting 64-bit mutual authentication and stream encryption
• Dual communication modes: Synchronous 2-Wire Serial Interface and Asynchronous ISO 7816-3 T=0 Protocol
• ISO 7816-2 compliant Smart Card Module package (M2 J)

Specialized ICS Applications

• Smart card applications requiring secure identity storage
• Embedded systems needing tamper-resistant configuration data
• Access control and authentication modules

Specialized ICS Procurement Notes

Verify that the M2 J module form factor matches the target smart card reader specifications. Confirm support for either synchronous TWI or asynchronous T=0 protocols based on system requirements. Ensure the host controller can handle the required voltage levels between 2.7V and 5.5V.

Specialized ICS Selection Notes

Select this model when 2-Kbit capacity is sufficient and smart card module packaging is required. Compare against other densities in the AT88SCxxxxC family if larger storage is needed. Verify compatibility with existing cryptographic libraries for implementing the mutual authentication sequence.

Specialized ICS Part Context

This part belongs to the AT88SCxxxxC series, which includes devices ranging from 1-Kbit to 256-Kbit. The 'MJ' suffix indicates the specific Smart Card Module package type, distinguishing it from standard plastic packages like SOIC or PDIP.

Specialized ICS Replacement Considerations

Direct replacements within the same package are limited. Other AT88SC models may require pinout adaptation or firmware changes due to different memory maps and zone configurations.
