The DeepCover Secure Microcontroller (MAXQ1103) is a low-power, 32-bit RISC device that combines high-performance, single-cycle processing, sophisticated tamper-detection technology, and cryptographic hardware. Advanced security features 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 MAXQ1103 is targeted at electronic commerce, banking, and data security systems that require the highest levels of secure access control, secure data storage, digital signature, or certificate authentication. A secure memory protection unit protects critical internal and external memory against tampering with triple-DES (3DES) encryption. Activation of a tamper sensor causes a rapid zeroization of critical data. An internal physical shield layer increases the complexity and cost of a physical attack against the die.A 32-bit MAXQ30 core powers the cryptographically secure MAXQ1103. Applications are supported with 512KB of high-performance internal flash memory for code/data storage and 32KB SRAM. Up to 8MB of additional external program and data memory is supported through a dedicated word-wide memory bus with programmable wait states. Additional peripherals such as serial I/O, 16-bit timers, hardware math accelerator, ISO 7816 UART, and a USB controller increase system utility while reducing component count.System security is enhanced by the addition of high-speed cryptographic hardware accelerators for ECDSA, DSA, RSA, Secure Hash Algorithm, and triple-key 3DES. The embedded hash engine supports multiple hash functions recommended by the National Institute of Standards and Technology (NIST). The true hardware random-number generator (RNG) supports FIPS 186-2 with an available software library. Note: Designers must have following documents to fully use all the features of this device.

The REF01 precision voltage reference provides a stable +10V output which can be adjusted over a ±3% range with minimal effect on temperature stability. Single-supply operation over an input voltage range of 12V to 40V, typical low current drain of 1mA, and excellent temperature stability are achieved with an improved bandgap design. Low noise, and low-power make the REF01 an excellent choice whenever a stable voltage reference is required. Applications include D/A and A/D converters, portable instrumentation, and digital voltmeters.

The REF43 is a low-power precision reference providing a stable +2.5V output independent of variations in supply voltage, load conditions or ambient temperature. It is suitable as a reference level for 8, 10 and 12-bit data acquisition systems, or wherever a stable, known voltage is required. Tight output tolerances and low thermal drift are assured by zener-zap trimming of both output voltage and its temperature coefficient. A unique curvature correction circuit reduces the thermal curvature, which is characteristic of many previous bandgap references.
