The DS2465P is indeed a chip dedicated to hardware security, effectively helping products prevent counterfeiting and unauthorised access. Mingjiada Electronics has stock available.

DS2465P Product Description

The DS2465P is a DeepCover® security authenticator. It is essentially a hardware security chip integrating an SHA-256 coprocessor and 1-Wire master functionality, designed for applications requiring high-strength anti-counterfeiting, tamper resistance, and data protection.

Its core mission is to serve as a secure bridge and protocol converter between the host system (typically connected via an I²C interface) and remote 1-Wire SHA-256 slave devices (such as iButton or other authentication tags). It provides the host with the necessary cryptographic processing power and interfaces, enabling robust security authentication systems even when the host itself has limited cryptographic capabilities.

Key Features and Advantages

Hardware Encryption and Security Authentication:

Employs hardware-based SHA-256 algorithm for robust data protection, offering superior security and efficiency compared to software implementations.

Features anti-cloning and tamper-proof capabilities with an embedded unique 64-bit ROM ID, effectively preventing device counterfeiting.

Supports secure storage of keys and sensitive data, which are difficult to read or replicate externally, delivering high-level security.

Low-Power Design:

Typical operating current of just 750µA, ideal for battery-powered portable devices or applications with stringent power consumption requirements.

Industrial-Grade Reliability:

Wide operating temperature range (-40°C to +85°C) adapts to harsh environmental conditions, meeting industrial application demands.

Simplified system design:

Integrated 1-Wire host functionality eliminates the need for complex 1-Wire timing implementation by the host processor, streamlining both hardware and software design.

Connects to the main controller via a simple I²C interface, minimising MCU pin resource consumption.
