General Description

The MAXQ1103 microcontroller is a low-power, 32-bit

RISC device that combines high-performance, single-

cycle processing, sophisticated tamper-detection tech-

nology, and cryptographic hardware. Advanced security

features are designed to meet the stringent requirements

of regulations such as ITSEC E3 High, FIPS 140-2 Level

3, and the Common Criteria Certifications. The

MAXQ1103 is targeted at electronic commerce, banking,

and data security systems that require the highest levels

of secure access control, secure data storage, digital

signature, or certificate authentication. A secure memory

protection unit protects critical internal and external

memory against tampering with triple-DES (3DES)

encryption. Tamper sensors instantly zeroize critical

encryption keys when physical intrusion is detected.

A 32-bit MAXQ30 core powers the cryptographically

secure MAXQ1103. Applications are supported with

512KB of high-performance internal flash memory for

code/data storage and 32KB SRAM. Up to 8MB of

additional external program and data memory is sup-

ported through a dedicated word-wide memory bus

with programmable wait states. Additional peripherals

such as serial I/O, 16-bit timers, hardware math accel-

erator, ISO 7816 UART, and a USB controller increase

system utility while reducing component count.

System security is enhanced by the addition of high-

speed cryptographic hardware accelerators for

ECDSA, DSA, RSA, Secure Hash Algorithm, and triple-

key 3DES. The embedded hash engine supports multi-

ple hash functions recommended by the National

Institute of Standards and Technology (NIST). The true

hardware random-number generator (RNG) supports

FIPS 186-2 with an available software library.
