High-Performance Secure RISC Microcontroller
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.
