AT88SC25616C-MJ

Specialized ICS Overview

The AT88SC25616C-MJ is a secure memory module from the CryptoMemory family, providing 256 Kbit (32 Kbyte) of EEPROM user memory. It integrates hardware cryptographic features including a 64-bit mutual authentication protocol and stream encryption. The device supports ISO 7816-3 asynchronous T=0 and synchronous 2-wire serial interfaces. Operating voltage ranges from 2.7V to 5.5V with an industrial temperature range of -40°C to +85°C. Memory endurance is rated at 100,000 cycles, and data retention is specified for 10 years.

Specialized ICS Feature Summary

• 256-Kbit User Memory: Divided into sixteen 2-Kbyte zones with programmable access rights.
• High Security: Features 64-bit mutual authentication, encrypted checksums, and four key sets.
• Smart Card Interface: Supports ISO 7816 Class A/B operation and asynchronous T=0 protocol.
• Configuration Zone: Includes 2-Kbit memory for passwords, keys, and security codes.

Specialized ICS Applications

• Embedded systems requiring secure nonvolatile storage.
• Smart card modules compliant with ISO 7816 standards.
• Authentication and encryption for sensitive system information.

Specialized ICS Procurement Notes

Verify that the ordering suffix MJ corresponds to the M2-J Smart Card Module package. Confirm the specific communication mode configuration (ISO or TWI) required for the application, as the module supports both asynchronous and synchronous protocols depending on initialization. Ensure compatibility with the host's voltage levels within the 2.7V to 5.5V range.

Specialized ICS Selection Notes

Select this component when 32 Kbytes of secure storage with hardware-based authentication is required. The M2-J package is suitable for smart card form factors. Consider the 10-year data retention and 100,000 cycle endurance limits for long-term reliability. Verify if the asynchronous T=0 protocol or synchronous 2-wire interface better suits the system architecture.

Specialized ICS Part Context

This part belongs to the Microchip CryptoMemory family, which offers densities from 1 Kbit to 256 Kbit. The AT88SC25616C provides the highest capacity in this series, featuring sixteen independent user zones. It replaces older Atmel designs with enhanced security protocols and flexible interface options for both embedded and smart card applications.

Specialized ICS Replacement Considerations

Other members of the AT88SC25616C family may serve as alternatives if different packaging is needed, such as the AT88SC25616C-SU (SOIC) or AT88SC25616C-PU (PDIP). These variants share identical electrical and functional specifications but differ in physical package type and mounting style.
