The MAXQ1850 is a low-power, 32-bit RISC device

designed for electronic commerce, banking, and data

security systems. It combines high-performance, single-

cycle processing, sophisticated tamper-detection technol-

ogy, 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 applications,

USB (slave interface with four end-point buffers), an RS-

232 universal synchronous/asynchronous receiver-

transmitter (USART), 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, compare,

and pulse-width modulation (PWM) operations.
