AT88SC0204C-MPTG

Specialized ICS Overview

The AT88SC0204C-MPTG is a secure memory IC from the CryptoMemory family, providing 2-Kbit (256 bytes) of EEPROM user memory. It features four 64-byte zones with programmable access rights and a 2-Kbit configuration zone containing a 37-byte OTP area for codes and a 160-byte area for keys and passwords. The device supports ISO 7816-3 asynchronous T=0 protocol and a synchronous 2-wire serial interface operating up to 1.0MHz. It operates on a supply voltage of 2.7V to 5.5V, includes high security features like mutual authentication and stream encryption, and is housed in an M2 P Smart Card Module package.

Specialized ICS Feature Summary

• 2-Kbit EEPROM user memory divided into four 64-byte zones with individual security settings
• Supports ISO 7816-3 asynchronous T=0 protocol and synchronous 2-wire serial interface
• High security with 64-bit mutual authentication, encrypted checksums, and stream encryption
• Configuration zone includes 37-byte OTP area and 160-byte area for keys/passwords

Specialized ICS Applications

• Smart card applications requiring secure data storage without a microprocessor OS
• Embedded systems needing secure nonvolatile storage for sensitive information
• Multi-application environments using multiple zones, key sets, and passwords

Specialized ICS Procurement Notes

Verify that the MPTG suffix corresponds to the M2 P Module package type as specified in the ordering information. Confirm the device meets the required temperature range and voltage specifications for the target application. Ensure compatibility with the host system's communication protocol, whether asynchronous T=0 or synchronous 2-wire.

Specialized ICS Selection Notes

Select this component when a small, secure memory footprint is needed with built-in cryptographic capabilities. The M2 P module format is suitable for smart card applications. Consider the 2-wire interface for embedded designs if synchronous communication is preferred. Evaluate the need for specific security levels, such as anti-tearing or write lock, during the personalization phase.

Specialized ICS Part Context

The AT88SC0204C is part of the Atmel CryptoMemory family, which offers devices ranging from 1-Kbit to 256-Kbit. This specific model provides 2-Kbit of user memory. The MPTG variant denotes the M2 P Module package, which is an ISO 7816 smart card module. The device is designed for high reliability with 100,000 cycle endurance and 10-year data retention.

Specialized ICS Replacement Considerations

Other members of the CryptoMemory family with different memory sizes may serve as alternatives if capacity requirements differ. Devices with similar pinouts and interfaces should be evaluated for functional compatibility. Verify that any replacement supports the required security features and communication protocols.
