USER’S GUIDE

Chapter 2. Hardware

This chapter describes the hardware features of the PIC32MX470 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 PIC32MX470 Curiosity Development Board is designed with a permanently mounted (i.e., soldered) PIC32MX470F512H 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 power 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. Once the debugger is successfully 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.

2.1.3 Programming and Debug

The PIC32MX470 Curiosity Development Board includes the PICkit on-board (PKOB) debugger based on the PIC24FJ256GB106 USB microcontroller. In addition, it pro-vides the option to use external debuggers, such as MPLAB REAL ICE or MPLAB ICD 3 by connecting to the In-Circuit Serial Programming™ (ICSP™) header, J16.

By default, the on-board debugger is connected to the programming pins (PGEC and PGED) of the PIC32 device. To use an external debugger, remove jumper J2 to disconnect the on-board debugger from driving the programming pins. Table 2-2 provides details of the various debuggers.

TABLE 2-2: DEBUGGER SELECTION

2.1.4 USB Connectivity

The PIC32MX470F512H microcontroller has an integrated full-speed USB module that enables the user to implement the USB functionality through the micro-AB USB connector (J12). Users can connect the development board for USB functionality using any one of these modes:

• Device Mode: Connect the host PC to the target USB connector (J12) using the USB Type A male to micro-B male cable. Use jumper J8 to select the required power source for the board.

• Host Mode: Connect the USB device to the target USB connector (J12) using a USB Type A Female to micro-B male cable (this cable is not included in the kit). Install a jumper in the J13 header to drive the VBUS line in Host mode. Use jumper J8 to select the power source from either the Debug USB connector or the external 5V input.

2.1.5 Switches

The PIC32MX470 Curiosity Development Board contains two push buttons: Reset but-ton (MCLR) and user-configurable button (S1). The Reset button is connected to the PIC32 Master Clear Reset line and the other is a generic user-configurable button. When a button is pressed, it will drive the I/O line to GND. Table 2-3 provides details of the push buttons.

2.1.6 LEDs

Four user-programmable LEDs are available on the PIC32MX470 Curiosity Development Board, and these LEDs can be turned ON/OFF using the connected GPIO pins. Table 2-4 provides details of the LEDs and related GPIO pins.

The RGB LEDs (LED4) are connected to the re-mappable pins with an output compare functionality to control the color and brightness with PWM output. In the RGB LED, red is the component of the GPIO pin RB10, green is the component of the GPIO pin RB3, and blue is the component of the GPIO pin RB2.

TABLE 2-4: LEDS

2.1.7 Oscillator Options

A 20 MHz crystal (X2) is connected to the on-board PIC32MX470F512H microcontrol-ler for precision clocking. The 12-Mbps USB full-speed signal rate specification requires ±0.25% or 2500 ppm clock accuracy. Therefore, an external crystal is required to meet the clock accuracy requirement for USB. Non-USB applications can use the internal RC oscillators.

The PIC32MX470 Curiosity Development Board also has provision for an external secondary 32 kHz oscillator (Y3); however, this component is not populated.

2.1.8 mikroBUS™ Sockets

Two mikroBUS sockets (J5, J10) are available on the development board, and these sockets can be used to expand the functionality using the MikroElectronika Click adapter boards. The mikroBUS connector consists of two 1x8 female headers with SPI, I2C, UART, RST, PWM, analog, 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:

• UART1, I2C1, SPI1 and OC1 peripheral instances to mikroBUS socket J5. The UART1 and SPI1 peripherals are also routed to the BM64 Bluetooth 4.2 Stereo Audio module.

• UART2, I2C2, SPI2 and OC2 peripheral instances to mikroBUS socket J10. The UART2, I2C2, and SPI2 peripherals are also routed to the X32 audio header.

2.1.9 X32 Audio Header

The PIC32MX470 Curiosity Development Board includes two X32 headers (J14, J15) to enable a connection to the Microchip Audio Codec daughter board. Table 2-5 provides the details of the available daughter board and for additional information, contact your local Microchip sales office.

For a complete list of currently available audio daughter boards, visit the microchipDIRECT web site (www.microchipdirect.com).

The PIC32MX470 Curiosity Development Board includes the footprint for the BM64 Bluetooth 4.2 Stereo Audio module to support Bluetooth audio. The PIC32 microcontroller uses the UART to send commands to the BM64 module and the I2S interface for audio data.

2.1.11 PIC32 I/O Header

The PIC32MX470 Curiosity Development Board provides a header (J17) to access unused microcontroller GPIO pins.

2.1.12 Peripheral Resource Assignment

The MCU peripheral instances, assigned for different hardware interfaces, are pro-vided in Table 2-6. The correct peripheral instance must be used in the application to use the respective hardware interface.
