The PICDEM™ System Management Kit is a demonstration and training tool for system integration and the design of a variety of applications. PIC^® microcontrollers provide powerful integrated peripherals, ideally suited for such integration tasks.
System integration refers to the consolidation of multiple systems within a unified design. The PICDEM System Management Board provides an I²C™ communications bus, typically found in applications such as personal computers or rack mount servers. The bus connects to multiple devices to monitor and record the health and status of the system. The PICDEM System Management Board integrates the functions of a dedicated Real-Time Clock (RTC), serial EEPROM, thermal management controller and analog-to-digital converter using a single PIC microcontroller.

In conjunction with the PICkit™ Serial Analyzer (included in the kit), communication to the emulated devices on the bus can be managed and monitored. The PICkit Serial Analyzer is a low-cost development tool that allows communication between a PC and the serial protocol of the system under test.
The PICDEM System Management board is populated with Microchip’s mid-range PIC16F886 microcontroller, which supports the following components and functions:
• MCLR reset line and switch
• Interrupt push button switches
• 4 LEDs
• I²C communications (SDA and SCL)
• USART communications (TX and RX)
• In-Circuit Serial Programming™ (ICSP™) pins (ICSPDAT and ICSPCLK)
• PWM output fan control
• Fan tachometer input line
• Heating element control line
• Temperature sensor input line from MCP9700
• 32.768 kHz crystal clock (T1OSO and T1OSI)
• 3V lithium battery backup
