Ultra-low power using ADI ChipDNA PUF technology
Maxim Launches Encryption Controller 'MAXQ1065'
Power consumption is 1/30th of that of comparable products.


Currently, tens of billions of IoT devices are in use, and malicious hacking against them is occurring frequently. Security threats to critical systems, such as public infrastructure, medical equipment, and industrial devices, are an imminent reality that requires appropriate protection.

On the 16th, Analog Devices (ADI) launched the 'MAXQ1065', an ultra-low power encryption controller that applies ChipDNA PUF (Physical Unclonable Function) technology to strongly protect edge-to-cloud IoT nodes, such as medical and wearable devices, from security attacks.

The MAXQ1065 security coprocessor operates at 100nA in power drop mode, consuming only one-thirtieth the power of comparable products. With a long lifespan and wide operating range, it is suitable for applications that operate for extended periods. In particular, through lifecycle management capabilities, it enables flexible access control during key lifecycle stages of devices and equipment. Its small size and small number of pins make it easy to integrate into medical and wearable devices.

This security coprocessor supports turnkey encryption for Silicon-based Security (RoT), mutual authentication, data confidentiality and integrity, secure boot, secure firmware updates, standard algorithm-based communication for key exchange and bulk encryption, and full Transport Layer Security (TLS). It also includes built-in 8KB secure storage with custom access control and lifecycle management capabilities for user data, keys, certificates, and counters.

The MAXQ1065 features a built-in TLS/DTLS 1.2 instruction set with ECDSA, ECDHE, and AES authentication to ensure secure communication. As an additional protection against security attacks, it utilizes irreversible ChipDNA PUF technology, which encrypts all stored data to prevent identification. This technology protects against attacks by discarding the self-value if there is an attempt to exploit the PUF encryption. It also supports security key programming services for customers who wish to initialize their keys, data, and lifecycle states.
