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 (MAXQ1851) 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 high-speed internal ring oscillator is provided to thwart attacks that rely on controlling the clock rate of the chip. To protect data, the MAXQ1851 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 MAXQ1851 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 MAXQ1851 includes 256KB of flash memory, 8KB of data SRAM, 4KB of AES encryptable secure battery-backed data SRAM, and 256-bit flip-flop based secure AES key storage. 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 MAXQ1851 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.
