Secure Cryptographic Controller
with Rapid Zeroization Technology
General Description
The MAXQ1850 is a low-power, 32-bit RISC device
designed for electronic commerce, banking, and data
security systems. It combines high-performance, sin-
gle-cycle processing, sophisticated tamper-detection
technology, and advanced cryptographic hardware to
provide industry-leading data security and secret key
protection.
Physical security mechanisms include environmental
sensors that detect out of range voltage or temperature
conditions, responding with an instantaneous zeroiza-
tion of critical data. Four self-destruct inputs are provid-
ed for additional tamper response. An internal shield
over the silicon provides protection from microprobe
attacks. A high-speed internal ring oscillator is provided
to thwart attacks that rely on controlling the clock rate of
the chip. To protect data, the MAXQ1850 integrates sev-
eral high-speed, analysis-resistant encryption engines.
Algorithms supported in hardware include AES (128-,
192-, and 256-bit), DES, triple DES (2-key and 3-key),
ECDSA (160-, 192-, and 256-bit keys), DSA, RSA (up to
2048 bits), SHA-1, SHA-224, and SHA-256. The
advanced security features of the MAXQ1850 are
designed to meet the stringent requirements of regula-
tions such as ITSEC E3 High, FIPS 140-2 Level 3, and
the Common Criteria certifications.
The MAXQ1850 includes 256KB of flash memory and
8KB of secure, battery-backed data SRAM. Several
communication protocols are supported with hardware
engines, including ISO 7816 for smart card applica-
tions, USB (slave interface with four end-point buffers),
an RS-232 UART, an SPI™ interface (master or slave
mode support), and up to 16 general-purpose I/O pins.
Other peripherals supported on the MAXQ1850 include
a true hardware random-number generator (RNG), a
real-time clock (RTC), a programmable watchdog timer,
and flexible 16-bit timers that support capture, com-
pare, and pulse-width modulation (PWM) operations.
