DS2475

DeepCover ECDSA Host Processor

with 1-Wire Master

General Description

DeepCover embedded security solutions cloak sensitive

Beneﬁts and Features

● High-Speed ECDSA Engine for Public-Key Signature

data under multiple layers of advanced physical security

to provide the most secure key storage possible.

Verification

● Implements NIST FIPS 186-Based ECDSA Algorithm

The DeepCover Elliptic Curve Digital Signature Algorithm

(ECDSA) coprocessor with built-in 1-Wire master

● Integrated NIST FIPS 180 SHA-256 Engine for

Efficient ECDSA Input Data Computation

(DS2475) enables the efficient implementation of pub-

lic-key based authentication when combined with an

ECDSA secure authenticator. Additionally, for operation

● 1-Wire Line Driver Supporting Both Standard and

Overdrive Communication Speeds

● Supports Power-Saving Sleep Mode (SLPZ Pin)

with 1-Wire ECDSA authenticators, an I C-to-1-Wire

protocol conversion function relieves the system host pro-

cessor from generating time-critical 1-Wire waveforms.

The DS2475 interfaces directly to standard (100kHz max)

or fast (400kHz max) I C masters. When not in use, the

DS2475 can be put in sleep mode where power consump-

tion is minimal.

● ±8kV ESD Protection on IO to GND (JESD22-A114

HBM, typ)

● Operating Range: 3.3V ±10%, -40°C to +85°C

● 6-Pin SOT23 Package

Ordering Information appears at end of data sheet.

Applications

● Authentication of Accessories

● Peripheral Authentication

● Authentication of Consumables
