DS3640

DeepCover Security Manager with I C Interface and 1KB

Nonimprinting Battery-Backed Encryption Key SRAM

General Description

Features

DeepCover® embedded security solutions cloak-sen-

sitive data under multiple layers of advanced physical

security to provide the most secure key storage possible.

S 1024-Byte Nonimprinting Key Memory with High-

Speed Erase

S 64-Byte General-Purpose RAM (Not Cleared)

The DeepCover Security Manager (DS3640) is a secure

supervisor with 1024 bytes of SRAM for applications

requiring the secure storage of encryption keys, includ-

ing POS terminals. The 1KB key memory is constantly

complemented in the background to prevent oxide

stress and memory imprint-ing. In the event of a

qualified tamper event, the key memory is rapidly

cleared.

S Real-Time Clock with Leap Year Compensation

Valid Up to 2100

S Watchdog Timer

S CPU Supervisor

S Four General-Purpose Tamper-Detect

Comparators with Associated Reference

S Three Tamper-Detect Logic Inputs

The device includes a real-time clock (RTC), CPU super-

visor, watchdog timer, and on-chip temperature sensor.

In the event of a primary power failure, an external

bat-tery source is automatically switched in to keep the

key memory, RTC, and tamper-detection circuitry active.

The DS3640 provides low-leakage tamper-detection

inputs for interface to external sensors, interlocks,

and anti-tamper meshes. The DS3640 will also invoke

a tamper event if the backup battery drops below a
