MAXQ1850 Datasheet | Maxim Integrated

EVALUATION KIT AVAILABLE Deep Cover Secure Microcontroller with Rapid Zeroization Technology and Cryptography General Description Deep Cover™ embedded security solutions cloak sensitive data under multiple layers of advanced physical security to provide the most secure key storage possible. The Deep Cover Secure Microcontroller (MAXQ1850) is a low-power, 32-bit RISC device designed for electronic merce, banking, and data security systems. It bines high-performance, single-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 rapid 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 highspeed 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 highspeed, 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 mon Criteria certifications. The MAXQ1850 includes 256KB of flash memory and 8KB of secure, battery-backed data SRAM. Several munication 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 SPI interface (master or slave mode support), and up to 16...
