ABRIDGED DATA SHEET Rev 0; 1/09 KIT ATION EVALU ILABLE AVA Secure Cryptographic Controller with Rapid Zeroization Technology General Description Features High-Performance, Low-Power, 32-Bit MAXQ30 RISC Core Single 3.3V Supply Enables Low Power/Flexible Interfacing DC to 16MHz Code Execution Across Entire Operating Range Up to 65MHz Cryptography Engine Execution to Reduce Processing Time On-Chip 2x/4x Clock Multiplier 33 Instructions 16-Bit Instruction Word, 32-Bit Internal Data Bus 16 x 32-Bit Accumulators Up to 16 General-Purpose I/O Pins 5V Tolerant I/O Virtually Unlimited Software Stack Optimized for C-Compiler (High-Speed/Density Code) Memory Features Security Features Additional Peripherals Low-Power Consumption See the Detailed Features section for complete list of features. MAXQ1850 The MAXQ1850 is a low-power, 32-bit RISC device designed for electronic commerce, banking, and data security systems. It combines high-performance, singlecycle 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 zeroization of critical data. Four self-destruct inputs are provided 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 several 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 regulations 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 RS232 universal synchronous/asynchronous receivertransmitter (USART), an SPITM 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.
