DeepCover Secure Magnetic Card Reader IC

General Description

DeepCover embedded security solutions cloak sensitive

Features

● 1.7V to 3.6V Operating Voltage

data under multiple layers of advanced physical security

to provide the most secure key storage possible.

● ISO 7811/7812/7813 Compliant

● Triple-Track Magnetic Stripe Head Interface

● Fast Wipe NV SRAM for Key Storage

● AES Encryption (128/192/256 Bit)

● DES/TDEA Algorithm Support

The DeepCover Secure Magnetic Card Reader

(MAXQ1743) is an integrated triple-track magnetic stripe

reader IC that adds security features to a POS terminal

or ATM card reader at the machine/card interface. Card

data can be encrypted using either AES or DES/TDES

algorithms. Security is further enhanced with the inclusion

of fast-wipe nonvolatile SRAM (NV SRAM), a hardware

random number generator (RNG), voltage attack sensors,

and a self destruct input pin. The NV SRAM clears its

contents when a tamper is detected by the on chip tamper

detection circuitry. The fast-wipe feature ensures that any

data in the NV SRAM is destroyed before any application

software can access it. The MAXQ1743 communicates to

● Random-Number Generator Hardware

● Self-Destruct Input for Tamper Detection

● Supply Overvoltage Detection

● Low-Power Operation (1.5mA typ)

● SPI or I C Interface

● Unique 64-Bit Serial Number
