FEATURES

Security features

Advanced features

CRC-16/32 generator provides strong error

detection of memory contents

Designed to meet the physical security requirements

of FIPS140 and Common Criteria certifications

Fine-line, top-level metal pattern detects intrusion of

the chip’s cryptographic boundary

Additional on-chip sensors detect out-of-range

environmental conditions that generate a tamper

response

True-time clock with alarm interrupt and wake-up

5kB internal SRAM with 1kB that can be allocated

to a stack for high-level language support

Programmable length MOVX instructions allow a

combination of fast and slow devices

On-chip power detection/selection circuits provide

power-up/down processor reset and early-warning

power-fail interrupt

The equipment enclosure can be monitored by

tamper response inputs for added protection

Fast write SRAM technology causes rapid

“zeroization” of secure information as a tamper

response

Watchdog timer

Proven 4-clock/machine cycle architecture

Single-cycle instruction executes in 160ns

Runs up to 25MHz clock rates

Dual data pointers can increment or decrement

independently

Eavesdropping on the external memory bus

prevented by single or triple-DES encryption of the

programs

Internal chip clock isolated from external system

clock by phase-locked loop

Asynchronous internal ring oscillator provides clock

for arithmetic operations

Automatic data pointer selection available

Resources inside cryptographic boundary include:

Modulo Arithmetic Accelerator (MAA) for up to

4096-bit (e.g., PKI)

DES and 112-bit key triple-DES engines

available for secret key cryptography

Random number generator

Memory Management Unit and 1kB cache

Firmware bootstrap loader resides in a 16kB

factory-programmed ROM

100

100-pin QFP

8051 compatible with expanded addressing

Linear address space directly accesses up to 8MB

of external memory

Dedicated memory and parallel I/O bus saves port

pins

Four 8-bit ports, one 6-bit port

80-pin QFP

Note: Some revisions of this device may incorporate deviations from published specifications known as errata. Multiple

revisions of any device may be simultaneously available through various sales channels. For information about DS5240 device

errata, contact the factory.
