DS28S60Q+T

Specialized ICS Overview

The DS28S60Q+T is a DeepCover secure coprocessor designed for embedded systems requiring confidentiality, authentication, and data integrity. It features an SPI slave interface operating at up to 20MHz with a fixed command set, eliminating the need for device-level firmware development. The device integrates hardware cryptographic blocks including ECDSA-P256, SHA-256, AES-128, and ECDHE key exchange. A NIST SP800-90B compliant True Random Number Generator (TRNG) supports on-chip operations. Nonvolatile storage consists of 3.6KB secured flash memory. Power supply ranges from 1.62V to 3.63V, with active current reaching 3mA during ECDSA operations.

Specialized ICS Feature Summary

• ChipDNA™ Physically Unclonable Function (PUF) generates unique keys without static storage
• NIST SP800-90B compliant True Random Number Generator (TRNG)
• High-speed SPI slave interface with 20MHz clock support in Mode 0 or Mode 3

Specialized ICS Applications

• Internet of Things (IoT) Device Security
• Key Management and Exchange
• End-to-End Encryption
• End-Point Authentication
• Prevention of Counterfeit Products

Specialized ICS Procurement Notes

Verify that the ordering suffix 'Q' corresponds to the -40°C to +105°C temperature range and 'T' indicates Tape & Reel packaging. Confirm RoHS compliance status via the manufacturer's official documentation. Ensure the host system provides adequate decoupling capacitors (4.7µF and 0.1µF) near the VDD pin as specified in the electrical characteristics.

Specialized ICS Selection Notes

Select this component when a fixed-function security solution is required without custom firmware development. The DS28S60Q+T is suitable for applications needing high-speed SPI communication up to 20MHz. Consider the 3.6KB secured flash capacity for storing certificates and keys. Verify that the host microcontroller supports SPI Mode 0 or Mode 3 protocols.
