MAXQ1850

EVALUATION KIT AVAILABLE MAXQ1850 DeepCover Secure Microcontroller with Rapid Zeroization Technology and Cryptography General Description DeepCover™ embedded security solutions cloak sensitive data under multiple layers of advanced physical security to provide the most secure key storage possible. The DeepCover Secure Microcontroller (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 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 r...
