AT88SC0204C-PU

Specialized ICS Overview

The AT88SC0204C-PU is a secure memory device from the CryptoMemory family, providing 2-Kbit (256 bytes) of EEPROM user memory. It operates within a voltage range of 2.7V to 5.5V and supports an asynchronous T=0 protocol or a synchronous 2-wire serial interface with a maximum clock frequency of 1.0MHz. The device features four independent 64-byte user zones, each configurable for distinct security access rights. Built-in cryptographic engines enable dynamic mutual authentication and stream encryption using up to four key sets.

Specialized ICS Feature Summary

• 2-Kbit EEPROM user memory divided into four 64-byte zones
• Supports ISO 7816-3 asynchronous T=0 protocol and 2-wire serial interface
• Integrated hardware engine for 64-bit mutual authentication and data encryption
• Configurable access rights, passwords, and write-lock mechanisms per zone

Specialized ICS Applications

• Smart card identity modules
• Embedded system secure storage
• Access control systems
• IoT device authentication

Specialized ICS Procurement Notes

Verify that the specific unit matches the industrial temperature grade (-40°C to +85°C) required by the application environment. Confirm the package type is the standard 8-lead PDIP (0.300 inch width). Ensure the ordering suffix corresponds to the desired configuration, as personalization settings are locked via fuses during manufacturing.

Specialized ICS Selection Notes

Select this model when 2-Kbit capacity is sufficient for the target application. Choose the -PU variant specifically for through-hole mounting requirements on PCBs. Verify compatibility with the host controller's interface capabilities, ensuring support for either the asynchronous smart card protocol or the synchronous 2-wire serial bus.

Specialized ICS Part Context

This component belongs to the Atmel Microchip CryptoMemory series, designed for high-security nonvolatile storage. The -PU suffix designates the 8-lead Plastic Dual Inline Package (PDIP), which provides a familiar pinout compatible with standard 2-wire Serial EEPROM footprints, facilitating integration into existing designs requiring physical robustness.

Specialized ICS Replacement Considerations

Direct replacements include other members of the AT88SC0204C family such as the AT88SC0204C-SH (SOIC package) or AT88SC0204C-MJ/MPTG (smart card modules). When substituting, ensure the replacement part maintains the same 2.7V–5.5V operating voltage and supports the required communication protocol mode.
