Mass Storage

There are three mass storage options available on the development board. 

SAMA5D29-Curiosity - Mass Storage

64 Mb Serial Quad I/O (SQI) Flash with EUI-48 and EUI-64 (U9)

U9 is a 64 Mb Serial Quad I/O (SQI) Flash with EUI-48 and EUI-64 memory (Microchip SST26VF064BEUI). It is connected to the Quad SPI Interface 1 (QSPI1) peripheral of the SAMA5D29. 

Secure Digital Multimedia Card (SDMMC) (J7)

J7 is a Secure Digital (SD) or MultiMediaCard (MMC) Memory Card slot. It is connected to the Secure Digital MultiMediaCard port 1 (SDMMC1) peripheral of the SAMA5D29. 

J7 can accommodate SD format radio modules. See the SAMA5D29-Curiosity User’s Guide for more information. 

Micro Secure Digital (J6) (Bottom Side)

J6 is a micro Secure Digital (SD) Memory Card slot mounted on the bottom side of the development board. It is connected to the Secure Digital MultiMediaCard port 0 (SDMMC0) peripheral of the SAMA5D29.

Communications

The SAMA5D29-Curiosity provides wired communications via Ethernet, USB, CAN, and wireless communications from SDMMC slot (J7) and Bluetooth® UART (J8). 

SAMA5D29-Curiosity - Communications

Ethernet (J15-J18)

The SAMA5D29-Curiosity contains a 10Base T/100Base-TX Ethernet Reduced Media-Independent Interface (RMII) available on connectors J15, J16, J17, and J18. Microchip provides a wide range of compatible Ethernet daughter boards that can be used for testing and evaluation. See the SAMA5D29-Curiosity User’s Guide for more information. 

USB (J1 and J11)

The SAMA5D29-Curiosity features two USB communication ports named USB-A (J1) and USB-B (J11). 

The USB-A port (J1) acts only as a USB device interface and is accessed via USB Type-C connector J1. 

The USB-A port (J1) can be used as a source of power for the development board. In most cases, this port is limited to 500 mA. See Power Options below. 

The USB-A port (J1) is used as the default serial port used to communicate with the SAM-BA® Monitor resident in the MPU. 

The USB-B port (J11) acts as a host and is accessed via USB Type-A connector J11. 

Controller Area Network (CAN) Flexible Data-Rate (FD)

The SAMA5D29 MPU contains two CAN-FD peripherals. By selecting a CAN-FD compatible mikro Click board™, the CAN-FD interfaces can be evaluated. 

MCAN0 signals are routed to the mikroBUS 1 connector (J19) by moving resistors R184 to R181 and R185 to R180. The resistors are located on the bottom side of the development board, below the mikroBUS 1 connector.

When evaluating MCAN0 signals, the LCD and ISC camera interfaces are unavailable. 

MCAN1 signals are routed to the mikroBUS 2 connector (J22) by moving resistors R192 to R189 and R193 to R188. The resistors are located on the bottom side of the development board, below the mikroBUS 2 connector.

When evaluating MCAN1 signals, the LCD and ISC camera interfaces are unavailable. 

Wireless Connectivity

Wireless communications (IEEE 802.11 b/g/n and Bluetooth) can be added to the SAMA5D29-Curiosity by plugging in SD memory card format radio modules such as the ATWILC3000-SD Evaluation Kit (P/N: AC164158) to SD Memory Card slot J7.  

Bluetooth modules that support the serial UART interface can connect to the 6-pin header J8.

Debugging

There is one method of debugging the SAMA5D29-Curiosity via JTAG (J27). In addition, a dedicated serial port for debugging and Console Serial Communications (J28). 

SAMA5D29-Curiosity - Debugging

JTAG (J27)

A JTAG interface to the SAMA5D29-Curiosity is provided by 20-pin connector J27. This facilitates software development and debugging by connecting an external JTAG debugger such as the J-32 Debug Probe or Segger J-Link BASE Debug Probe

The JTAG interface signals voltage levels are 3.3V. 

Serial Debug Port (J28)

The Serial Debug Port (J28) is a dedicated TTL-level serial port connection between the SAMA5D29 and J28. A level shifter (U12) allows either 3.3 or 5.0 VDC levels. To interface between J28 and the host computer, you will need a USB-to-Serial (3.3 or 5.0 VDC) TTL level adapter with a 6-pin single-in-line 0.1” pitch connector.  

Take care to align Pin 1 (GND) of the header J28 to the USB-to-Serial adapter Pin 1 (look for an arrow on the connector and a black wire). 

A terminal emulation program running on a host computer provides a user interface to interact with the target console.

User Interface

SAMA5D29-Curiosity - User Interface

Red-Green-Blue (RGB) LED (D5)

The SAMA5D29-Curiosity features one RGB LED (D5). 

Pushbuttons (SW1-SW3)

The SAMA5D29-Curiosity contains three pushbuttons: 

  • USER (SW1): User push button is the connector to PIO PA17 and is available for the user’s usage. 
  • RESET (SW2): Reset push button, when pressed the system resets. 
  • START (SW3): When pressed it will initiate the PMIC start-up sequence if the buck converters are off. The PMIC will also assert the SAMA5D29 wakeup (WKUP) signal to wake the MPU from a low-power state. 

Liquid Crystal Display (LCD) Interface (J23)

The SAMA5D29-Curiosity contains an 18-bit parallel LCD Interface that supports various LCD Displays. The Liquid Crystal Display Controller (LCDC) I/O lines are available on the baseboard 50-pin Flexible Flat Cable (FFC) / Flexible Printed Circuit (FPC) connector J23. 

The default supply voltage to the LCD Interface is 5 VDC. The supply voltage can be changed to 3.3 VDC by moving the zero-ohm resistor from R196 to R197. 

Image Sensor Controller (ISC) Camera Interface (J24) (Not populated)

The SAMA5D29 contains an Image Sensor Controller (ISC) that supports incoming data from a parallel CMOS/CCD sensor. The system supports an active interface and the ITU-R BT 656/1120 422 protocol with an 8-bit or 10-bit data width and raw Bayer format. The ISC I/O lines are available on baseboard 2x15 connector J24 (not populated).

mikroBUS™ (J19 and J22)

mikroBUS™ socket is a proprietary communication and plugin standard for small interface boards called Click boards that extends the capabilities of the development board by offering Serial Peripheral Interface (SPI), UART, TWI, and PWM-based sensors and devices. They are made by MikroElektronika, a producer and retailer of hardware and software tools for developing embedded systems.

The SAMA5D29-Curiosity contains a 40-pin GPIO connector (J25) for use. This connector is compatible with the Raspberry Pi expansion header. 

Multifunction 20-Pin Connector (J26) (Not populated)

The 20-pin Multifunction connector provides connectivity to alternate functions of certain SAMA5D29 PIOs. One such function is bringing the NAND Flash interface to this connector. Refer to the SAMA5D29-Curiosity User’s Guide for more information. 

Tamper (J29) and System Signals (J30) Connectors (Not populated)

The SAMA5D29-Curiosity board provides six tamper pins for static or dynamic intrusion detection on connector J29 (not populated).  

The PMIC High-Power Mode (HPM) signal, used to enable the PMIC High-Power mode, is present on J29 pin 8. 

Unused I/O signals from the SAMA5D29 are routed to connector J30 (not populated).

Power Options

There are two options to power the SAMA5D29-Curiosity. 

SAMA5D29-Curiosity - Power Options

USB-A Port (J1)

The USB-A port (J1) is a USB-C connector and can be used as a source of power to the development board. In most cases, this port is limited to 500 mA. 

DC Jack (J2)

The SAMA5D29-Curisosity can be powered by an external 5.0 VDC power supply. The connector (J1) is a 2.1 mm coaxial center-positive. 

DO NOT exceed 6.0 VDC on DC Jack (J2). 

If both J1 and J2 are powered at the same time, automatic switching circuitry prioritizes power from the DC Jack (J2).
