APPLICATION NOTE 4312
Getting Started with DeepCover Secure Microcontroller
(MAXQ1850) EV KIT and the CrossWorks Compiler for
the MAXQ30
Dec 22, 2009
Abstract:
This application
note describes how to create, build, and debug applications targeted to the DeepCover
®
Secure Microcontroller (MAXQ1850). The examples use the MAXQ1850 evaluation (EV) kit and the CrossWorks C
compiler available from Rowley Associates.
Introduction
Maxim's DeepCover
®
Secure Microcontroller (MAXQ1850) is a high-performance, high-security, low-pin-count, 32-bit
RISC microcontroller designed for electronic commerce, banking, and data-security applications. The microcontroller
executes 16-bit instructions and has a 32-bit data path. Most instructions execute in a single clock cycle, making the
MAXQ1850 a very high-performance RISC microcontroller. The MAXQ1850 also has a number of important security
features, including:
2048-bit modular arithmetic accelerator supporting RSA, DSA, and ECDSA
Cryptographic hardware accelerators supporting AES-128, AES-192, AES-256, SHA-1, SHA-224, SHA-256,
DES, and 3DES
True hardware random number generator
8KB low-leakage battery-backed NVSRAM
Four self-destruct inputs
Tamper detection with fast key/data erase
Environmental sensors (e.g., temperature, voltage) to detect out-of-range conditions
The MAXQ1850-KIT, an EV (evaluation) kit, is an ideal platform for prototyping secure applications. The EV kit
provides an RS-232 serial port, two smart-card slots (one full size and one SIM card), a USB connector, an LCD
screen, a 16-pushbutton keypad, and a prototyping area.
Setting up the MAXQ1850 EV Kit
The MAXQ1850-KIT board is shown in Figure 1. The following hardware components are contained in the EV kit
package, and are used for implementing this application note:
1. MAXQ1850-KIT board
2. JTAG board
3. JTAG cable (connects MAXQ1850-KIT board and JTAG board)
4. 9-pin serial cable
5. Two regulated power supplies (5V, ±5%, 300mA, center positive)
