PICDEM SYSTEM MANAGEMENT USER’S GUIDE Chapter PICDEM System Management INTRODUCTION The PICDEM System Management Board is a demonstration and development tool designed for system management applications. System management applications monitor platform physical health characteristics such as temperatures, voltage, fan speed and chassis intrusion. These applications typically utilize independent I2C devices like real-time clocks, EEPROMs, Analog-to-Digital Converters ADC , and thermal management controllers to monitor and control physical health characteristics. The PICDEM System Management Board demonstrates how microcontrollers can add value to these applications in terms of flexibility and cost. I2C devices can be implemented using the Synchronous Serial Port module in conjunction with the many other available peripherals. The programmability of a microcontroller I2C device allows flexibility in the additional intelligent features that can be implemented as well as the easy adaptability of software when requirements change. A new address masking feature of the Syncronous Serial Port module allows the microcontroller to respond to multiple I2C device addresses. The PICDEM System Management uses this feature to implement four I2C devices a real-time clock, ADC, EEPROM, and thermal management controller on one single microcontroller. Integrating these functions on a single microcontroller provides savings in the bill of materials cost and board space. For additional information on system monitoring, see Chapter “Background” of this User's Guide. HIGHLIGHTS This chapter discusses the features of the PICDEM System Management Board Kit.
