1 Introduction The MicroZed Carrier Card for Arduino™ (MZCC_ARD) is a multi-function, low-cost development board designed to facilitate easy evaluation of Avnet MicroZed SOM boards together with Arduino-compatible Shields and Microcontroller boards as well as Pmod-compatible peripheral boards.

Note: Please refer to the “MicroZed Carrier Card for Arduino™ Getting Started Guide” for detail of the software aspects, plus additional information on practical application of this Carrier Card in different use cases.

1.1 MZCC_ARD Features – An Arduino-compatible shield site connected to the MicroZed SOM, to facilitate the addition

of 3rd-party shield expansion boards.

– PMOD™-compatible connector connected to PS side of Zynq device on MicroZed SOM, providing a high-throughput SDIO/SPI interface for Pmod-compatible Communications-, Analog-, or Sensor boards.

– PMOD™-compatible connector connected to PL side of Zynq device on MicroZed SOM, that facilitates additional flexible interfacing options via the FPGA fabric

– PMOD™-compatible connector connected to LP (Low-Power) MCU sub-system, for I2C/UART interface to additional sensor solutions or Low Power RF wireless solutions (BTLE / Zigbee / ANT…)

– A set of Low Power MCU sub-system connectors:

– Capable of controlling the power to the SOM, including all of the voltage rails.

– Facilitates offload of tasks (that don’t require Apps Processor performance or FPGA functionality) to minimize overall board power-consumption.

– For Sensor-hub functionality and continuous sampling of environmental sensors (Ambient Light Sensor, 3D-Accelerometer, 3D Magnetometer plus TBD other sensors via Pmod interface)

– LP MCU sub-system that also allows stacking of Freescale FRDM-FXS-MULTI Sensor board.

– LP MCU Power Management, where the LP MCU can control the carriers’ main 3.3V power supply and the MicroZed SOM’s power state via the VCCIO_EN pin on JX2.

An example setup with FRDM-KL46Z board, MicroZed SOM and MZCC_ARD carrier card is shown on the next page.

Notes: The carrier card may be used without the FRDM-KL46Z microcontroller board but always requires the MicroZed SOM to be present.

2.2 LP-PMOD Connector This connector is referred to as the Low-Power Pmod connector. It is used to interface UART0 and I2C0 signals to the KL46 MCU. Only one interface type can be used at a time. Jumpers have been provided so the user can select which interface to use. JP1 is used to select which power the LP PMOD is to use. If the user selects position 1-2, the maximum power that should be drawn from the PMOD circuit is 300 mA. This allows a margin of 200 mA for the Low Power regulator.

Selection of the desired peripheral interface is by means of jumpers (JP1, JP2, JP3)

2.3.3 MicroZed to PS-PMOD Connector MIO interface signals (MIO 0, MIO 9-15) are routed to the PMOD-MZ connector. The Pmod pinout chosen facilitates the use of Zynq PS hardened peripherals such as SDIO (4 lane) or SPI for host communication with one of Avnet’s Wi-Fi Pmod wireless boards.

Alternatively, different PS peripherals (eg. I2C or UART) could be instantiated to use these MIO pins for support of other Pmod board types.

2.5 System Power

2.5.1 Power Input The Adaptor Board input voltage is 5V via a micro-USB connector on upper edge of the Adaptor Board.

– Micro USB AC/DC wall adapter:

– Primary 5V, 2A, Micro USB connector.

– Provides primary power through D1. D1 is placed to prevent over USB voltage conditions ensuring 5.0V is provided to the regulators and the SOM.

– An optional DC jack may be placed by the user at location J4. The recommended CUI part number is PJ-002AB-SMT. C18 – C20 can be placed pending the ripple current of the chosen power supply.

2.5.2 Voltage Regulators The following table lists the power solution for the MZCC_ARD. 3.3V (P3V3_MZ) is provided for the Zynq PL I/O banks 34, 35 and 13 (if 7Z020 is populated on MicroZed).

– VIN_HDR is connected to the USB power input, 5.0V. This rail provides the SOMs primary power source.

– Regulator 1 is the primary board power regulator and is used to power the I/O interfaces on both the SOM and the MZCC_ARD board.

– Regulator 2 is always on and used to provide power when the primary regulator is turned off during sleep condition. This ADP124 part can be changed to ADP125 adjustable version if the user chooses. R27 would then need to be calculated and placed to determine the desired P3V3_PM value.

The table below shows the voltage rails, currents, and tolerances.

2.5.3 MicroZed Power Sequencing and control circuits – PWR_EN signal, active high, is the output of a GPIO pin on the KL46 MCU. It provides

on/off control of the power supplies on MicroZed and the Adaptor Board. A 3.3V to 5V (VIN) level translator, Q1, is used to interface to the SOM’s 5V PWR_EN signal.

– VCCIO_EN signal, active high, JX2.10, originates on the MicroZed and is the output of the 1.8V regulator, PG_1V8. This signal enables the MZCC_ARD P3V3_MZ regulator, turning on the Carrier board’s primary 3.3V power supply. If VCCIO Enable pin is lower than 0.77V, as determined by U2 and U3, the MZCC_ARD will not power on. This allows the SOM to control MZCC_ARD’s primary 3.3V power supply.

– PG_MODULE signal, JX2.11, (labeled PG_CARRIER in the below figure) is active high and is pulled up by MicroZed’s +3.3V PG_MODULE signal and the MZCC_ARD’s P3V3_MZ net. These signals are wired OR to the MicroZed’s 3.3V power supply, the Zynq’s Power On Reset signal and the MZCC_ARD board’s 3.3V power supply. When the power supplies are valid on both the SOM and Carrier, the PG signal de-asserts the Zynq POR signal allowing the MZCC_ARD board to power on.

– The following diagram illustrates the power supply sequencing on power up. Note Vin and PWR_Enable can come up simultaneously, but shown staggered as PWR_Enable can come up later.

4 Addendum Additional information on board types and uses. Note that this is provided to the customer for informational purposes only and may change without notice by Avnet or the module manufacturers.

4.1 Arduino Shield Expansion Site for the MCU Board A special use-case is allowed for where Freescale’s FRDM-FXS-MULTI Sensor board is stacked onto the FRDM-KL46Z MCU board to facilitate a practical demo of key products from Freescale’s Sensor portfolio. Attaching the sensors to the MCU rather than the Zynq SoC allows the offload of sensor sampling and aggregation to the MCU subsystem for maximum power-efficiency, permitting MicroZed to remain powered-down for a higher proportion of the time.

This solution is specific to the use of Freescale’s Kinetis KL46 and MULTI Freedom boards. Adding FRDM-FXS-MULTI to the system requires consideration of the electrical and mechanical aspects.

1. Electrical interfaces from the FRDM-KL46Z on connectors JM2 and JM1 are now allocated between MicroZed, PL-PMOD and FRDM-FXS-MULTI

2. Mechanical mounting of the FRDM-FXS-MULTI requires 2 additional connectors (JM3, JM4). A summary of both sets of connectors is shown below:

a. Fitted to Carrier Card for all use-cases and configurations: JM2 and JM1 (mounted on Carrier Card) are long-tailed 2x10 and 2x8 sockets

b. Optional, to MZCC_ARDommodate FRDM-FXS-MULTI. JM3 and JM4 (not on Carrier Card, to provide seperately) are long-tailed 2x6 and 2x8 sockets required to mate the free-standing left-hand side connectors between these boards.

The applicable SAMTEC part numbers are: (ftp://ftp.samtec.com/webfiles/PDF/SSQ_TH.PDF) JM2: SSQ-110-23-G-D [2x10 (20 position) Through-Hole .025” SQ Post Socket] JM1, JM3: SSQ-108-23-G-D [2x8 (16 position) Through-Hole .025” SQ Post Socket] JM4: SSQ-106-23-G-D [2x6 (12 position) Through-Hole .025” SQ Post Socket]

4.2 Arduino Shield Expansion Site for MicroZed – Connected to MicroZed, a subset of the Arduino R3 footprint is supported.

– Supports 3.3V I/O shields (No support for 5V shields!)

– The following Shield interfaces are routed to the applicable Zynq PS peripherals

– SPI

– I2C

– UART

– T0, T1

– INT0, INT1

– A useful table of common shields and the interface pins they require is located at: http://playground.arduino.cc/Main/ShieldPinUsage

– Example 3.3V Shields suitable for this system include the following:

– SMARTGPU2 TFT LCD shield ($89)

– XBEE Wireless SD Shield

– Full details of the signals routed from MicroZed to the Arduino Shield are tabled in section 2.5.2
