Chapter 2. Hardware
This chapter describes the hardware features of the PIC32MZ EF Curiosity
Development Board.
2.1 HARDWARE FEATURES
Only certain features of the development board are discussed in this section. Refer to
Figure 1-1 in Section 1.2 “Development Board Functionality and Features” for
their locations.
2.1.1 Processor
The PIC32MZ EF Curiosity Development Board is designed with a permanently
mounted (i.e., soldered) PIC32MZ2048EFM100 microcontroller (U9).
2.1.2 Power Supply
Power can be supplied to the development board from the host PC using a Type A
male-to-mini B USB cable or by using an external +5V supply. Jumper J8 is used to
select the voltage source for the development board. Table 2-1 provides the details of
the power supply sources available for the development board.
The +3.3V power supply for the microcontroller is generated by the MPC1727 voltage
regulator.
TABLE 2-1: DEVELOPMENT BOARD POWER SUPPLY SOURCES
If the PICkit™ On-board (PKOB) debugger is connected to a host PC, it enumerates
with the host computer and once it has successfully been enumerated, it turns on the
main board power supply (+3.3V and +5V) using the high side power switch
(MIC2005A) by driving the ENABLE signal high. Figure 2-1 shows the power topology
for the development board.
