AT88SC3216C-MJTG

Specialized ICS Overview

The AT88SC3216C-MJTG is a secure memory IC from the CryptoMemory family, manufactured by Microchip Technology. It provides 32 Kbit (4-Kbyte) of EEPROM user memory organized into sixteen 256-byte zones. The device integrates a hardware cryptographic engine supporting 64-bit mutual authentication and stream encryption. It operates within a voltage range of 2.7V to 5.5V and supports both asynchronous ISO 7816-3 T=0 smart card protocols and synchronous 2-wire serial interfaces. The component is housed in an M2-J Smart Card Module package with Cut Tape (CT) packaging.

Specialized ICS Feature Summary

• 32-Kbit User Memory: Divided into 16 independent 256-byte zones with programmable access rights.
• Hardware Security Engine: Implements 64-bit dynamic symmetric mutual authentication, encrypted checksums, and stream encryption.
• Dual Protocol Support: Compatible with ISO 7816-3 Asynchronous T=0 protocol for smart cards and Synchronous 2-wire Serial Interface for embedded systems.
• Configuration Zone: Includes 2-Kbit configuration memory with 37-byte OTP area and 160-byte area for keys/passwords.

Specialized ICS Applications

• Smart Card Identity Modules
• Embedded Secure Data Storage
• Access Control Systems
• IoT Device Authentication

Specialized ICS Procurement Notes

Verify that the specific ordering suffix -MJTG corresponds to the M2-J Module form factor with TWI interface support as indicated in local product fields. Confirm the commercial temperature grade (0°C–70°C) aligns with application requirements, as industrial variants (-40°C–85°C) exist under different suffixes like -PU or -SU. Ensure compatibility with existing smart card readers regarding the asynchronous T=0 protocol if utilized.

Specialized ICS Selection Notes

Select this model when a smart card module form factor is required for ISO 7816 compliance. The M2-J package is distinct from standard surface-mount packages like SOIC or PDIP. Consider the 1.0 MHz synchronous clock limit for embedded applications versus the higher baud rates supported by the asynchronous smart card mode. Verify that the 32-Kbit capacity meets storage needs, as the family ranges from 1-Kbit to 256-Kbit.

Specialized ICS Part Context

The AT88SC3216C belongs to the CryptoMemory series, originally developed by Atmel before its acquisition by Microchip Technology. This series represents a line of high-security EEPROMs designed to replace standard non-volatile memory in security-sensitive applications. The -MJTG variant specifically denotes the M2-J module package configuration intended for smart card integration.

Specialized ICS Replacement Considerations

Direct pin-compatible replacements are limited due to the specialized M2-J module package. Other members of the CryptoMemory family (e.g., AT88SC1616C, AT88SC6416C) offer similar security features but differ in memory density. Standard EEPROMs cannot provide the integrated hardware encryption and mutual authentication capabilities of this component.
