Chapter 2. Hardware

This chapter describes the hardware features of the PIC32MK MCM Curiosity Pro development board.

HARDWARE FEATURES

The following key features of the development board are presented in the order given in Section 1.3 “Kit Functionality and Features”. See Figure 1-2 for their locations on the devel-opment board.

Processor Support
The development board kit is designed with a permanently mounted (that is, soldered) proces-sor, PIC32MK1024MCM100.

Power Supply
Power is supplied to the development board by a USB bus power, which is connected to the USB debug connector J500.
One green LED (D205) is provided to indicate the PIC32 device is powered up.

PIC32 USB Connectivity

Using any one of the following options, users can connect to the PIC32 USB microcontroller:

• Host mode – Connect the device to the Type-A connector J201, which is located on the top of the starter kit. If using the Debug USB port to power the Host port, install the jumper JP204 to short the back-power prevention diode. A maximum of ~400 mA can be supplied from the Debug USB port to the Host port using this method. If the full 500 mA supply is needed, an external supply must be connected to the application board, and jumper J204 must be removed to prevent back-powering the Debug USB port.
• Device mode – Connect the debug mini-B USB cable to port J500 and then connect the starter kit to the host by using a cable with a Type-B micro-connector to the starter kit’s micro-A/B port J200. The other end of the cable must have a Type-A connector. Connect the Type-A connector to a USB host. Jumper J204 must be removed.
• OTG mode – Connect the starter kit to the OTG device using an OTG micro-A/B cable to the micro-A/B port J200, which is located on the bottom of the board. The starter kit provides an on-board power supply capable of providing 120 mA maxi-mum. This supply is controlled by the PIC32MK1024MCM100 device. Jumper J204 must be removed.

Switches

Push button switches provide the following functionality:

• S1: Active-low switch connected to RG11
• S2: Active-low switch connected to RF13
• S3: Active-low switch connected to RF12
• /MCLR: Connected to Microcontroller/MCLR

These switches do not have any debounce circuitry and require internal pull-up resistors, this enables the user to investigate software debounce techniques. When Idle, the switches are pulled high (+3.3V), and when pressed, they are grounded.

LEDs
The LEDs, LED1 through LED3, are connected to the PORTG pins (RG12 through RG14) of the processor. The PORTG pins are set high to illuminate the LEDs.

Oscillator Options
A 12 MHz oscillator circuit (Y4) is connected to the on-board microcontroller. This oscillator circuit functions as the controller’s primary oscillator.
Use of an external crystal or external oscillator is required to develop USB applications. The USB specification dictates a frequency tolerance of ±0.05% for high speed. Non-USB applications can use the internal oscillators.
The development board kit also has provisions for an external secondary 32 kHz oscillator (Y4); however, this is not populated. A suitable oscillator, ECS- 3X8, can be obtained from Digi-Key: P/N – X801-ND CMR200TB32.768KDZFTR.
The PKoB 4 Debugger IC is independently clocked and has its own 12 MHz clock oscillator.

mikroBUS™ Sockets
Two mikroBUS sockets, J300 and J301, are available on the development board. These sockets can be used to expand the functionality using the MikroElectronika Click adapter boards. The mikroBUS connector consists of two 1×8 female headers with SPI, I2C, UART, RST, PWM, analog, and interrupt lines as well as 3.3V, 5V, and GND power lines.
The GPIO pins for the mikroBUS sockets are assigned to route, as follows:

• UART4, I2C4, SPI6, and OC1 peripheral instances to mikroBUS socket J300
• UART3, I2C2, SPI2, and OC3 peripheral instances to mikroBUS socket J301
  Note: UART3, I2C2, and SPI2 peripherals are also routed to the X32 audio header.

Audio Header

The PIC32MK MCM Curiosity Pro includes two X32 headers, J302 and J303, to enable a con-nection to the Microchip Audio Codec Daughter Board. Table 2-2 provides the details of the avail-able Audio Codec Daughter Board, and for additional information, contact your local Microchip sales office.
For a complete list of currently available Audio Codec Daughter Boards, visit the microchipDIRECT web site: www.microchipdirect.com.

TABLE 2-1: AUDIO CODEC DAUGHTER BOARD

Peripheral Resource Assignment
The MCU peripheral instances, assigned for different hardware interfaces, are provided in Table 2-2. The correct peripheral instance must be used in the application to use the respective hardware interface.
