MAXQ1062EUD+T

Application Specific Microcontrollers Overview

The MAXQ1062EUD+T is a DeepCover cryptographic controller in a 14-TSSOP package, designed for embedded security applications. It features 8KB of user-programmable EEPROM for secure key and certificate storage. The device supports SSL/TLS/DTLS implementations via high-level abstraction functions, including TLS key negotiation, ECDSA authentication, and packet encryption. It integrates hardware engines for AES-128/-256 (ECB, CBC, CCM), ECC (NIST P-256/384/521, Brainpool), SHA-2, and MAC algorithms. Communication occurs over SPI or I2C interfaces. The component operates within a temperature range of -40°C to +109°C.

Application Specific Microcontrollers Procurement Notes

Verify the 'T' suffix indicates tape and reel packaging configuration. Confirm the specific revision level matches project requirements. Ensure compatibility with existing SPI or I2C host controllers. Check for RoHS compliance status as indicated by the '+' designation in related part numbers.

Application Specific Microcontrollers Selection Notes

Select this model over the MAXQ1061 variant when 8KB of EEPROM is sufficient for the required certificate and key storage capacity. The 14-TSSOP package is suitable for space-constrained designs compared to the 20-pin TQFN option. Ensure the application utilizes either SPI or I2C interfaces as supported by the device architecture.

Application Specific Microcontrollers Part Context

This component belongs to the Maxim Integrated DeepCover family of embedded security solutions. It serves as a coprocessor to guarantee confidentiality, authenticity, and integrity for connected products. The device allows integration into existing designs without firmware development for cryptographic functions.
