DS2477Q+U

Specialized ICS Overview

The DS2477Q+U is a DeepCover Secure SHA-3 Coprocessor with ChipDNA PUF protection, manufactured by Analog Devices Inc./Maxim Integrated. It integrates a FIPS 202-compliant SHA-3 engine, TRNG, and 2Kb secured EEPROM within a 6-pin TDFN-EP package (3mm x 3mm). The device operates on a supply voltage of 2.97V to 3.63V and supports an operating temperature range from -40°C to +85°C. It features an I2C interface for host communication and a built-in 1-Wire master for peripheral authentication.

• FIPS 202-compliant SHA-3 algorithm enables bidirectional authentication and HMAC support
• Built-in 1-Wire master with standard and overdrive timing speeds and active pullup capabilities
• I2C communication interface supporting clock frequencies up to 1MHz

Specialized ICS Applications

• Authentication of medical sensors and tools
• Secure management of limited-use consumables
• IoT node authentication
• Peripheral authentication
• Printer cartridge identification and authentication

Specialized ICS Procurement Notes

Verify component authenticity through authorized distributors or the manufacturer directly. Confirm RoHS compliance status via official documentation. Check current production availability as supply may be restricted. Ensure proper handling of the exposed pad in the TDFN-EP package for thermal management and ground connection.

Specialized ICS Selection Notes

Select this component when secure authentication and anti-tamper protection are required for 1-Wire peripherals. The integrated 1-Wire master simplifies host processor load by handling time-critical waveforms. Verify that the application environment falls within the specified -40°C to +85°C temperature range and 2.97V to 3.63V supply voltage limits.

Specialized ICS Part Context

The DS2477 belongs to the Maxim Integrated DeepCover Secure family, designed for high-security applications. It combines cryptographic functions with physical security features like the actively monitored die shield. The Q suffix typically denotes industrial temperature grade variants within the product line.

Specialized ICS Replacement Considerations

Consult official Analog Devices documentation for qualified replacement parts. Cross-referencing should verify identical pinout, electrical characteristics, and security feature sets. No direct substitute part numbers are confirmed in the provided source material.
