MAXQ1061EUD+

Specialized ICS Overview

The MAXQ1061EUD+ is a DeepCover cryptographic controller in a 14-TSSOP package. It provides hardware-accelerated security for embedded devices, supporting SSL/TLS/DTLS implementations without firmware development. The device features 32KB of user-programmable EEPROM for secure key and certificate storage. It includes a dedicated 128-bit AES engine over SPI for stream encryption up to 20Mb/s. Communication interfaces include I2C (up to 400kbps) and SPI. Supported algorithms encompass AES-128/-256, ECC NIST P-256/384/521, ECDSA, SHA-256/384/512, and HMAC variants. It operates within the -40°C to +105°C temperature range.

Specialized ICS Feature Summary

• Integrated TLS/DTLS toolbox with hardware AES-GCM/ECB engine (up to 20Mb/s)
• 32KB nonvolatile EEPROM with flexible file system and access control
• Supports ECC NIST P-256/384/521, Brainpool curves, and ECDSA signatures
• Includes True Random Number Generator (TRNG) and on-chip key generation

Specialized ICS Applications

• Internet of Things (IoT) nodes
• Industrial networking and Programmable Logic Controllers (PLCs)
• Smart metering and SCADA systems
• Secure access control and electronic signature generation

Specialized ICS Procurement Notes

Verify the specific suffix 'EUD+' corresponds to the 14-TSSOP package variant. Confirm RoHS compliance status via the manufacturer's current documentation. Check for any lifecycle changes or obsolescence notices prior to procurement. Ensure supply chain authenticity through authorized distributors.

Specialized ICS Selection Notes

Select the MAXQ1061EUD+ when 32KB of secure storage is required; the MAXQ1062 variant offers only 8KB. Choose this component if the application demands offloading TLS handshake and encryption tasks from the host MCU. Verify that the host processor supports either I2C or SPI communication protocols as dictated by the specific security mode (TLS vs. AES-SPI).

Specialized ICS Part Context

This part belongs to the Maxim Integrated DeepCover family of embedded security solutions. It is designed to protect software IP, communications, and data integrity in connected devices. The EUD+ designation specifically identifies the 14-pin Thin Shrink Small Outline Package (TSSOP) configuration with lead-free/RoHS compliance.

Specialized ICS Replacement Considerations

The MAXQ1062EUD+ is a pin-compatible alternative with reduced 8KB EEPROM capacity. Other DeepCover controllers may offer different interface options or algorithm support but require schematic and software re-evaluation.
