Carrier Card Design
Supply
Your carrier card must supply the MicroZed board as follows:
| Voltage | Signal | Pin |
|---|---|---|
| 5V | 5V | JX1 57, 58, 59, 60 |
| 3.3V | 3.3V_B34 | JX1 78, 79, 80 |
| 3.3V | 3.3V_B35 | JX2 78, 79, 80 |
| Gnd | 0V | several on JX1 and JX2 |
Other necessary voltages (1.0V, 1.8V, 1.5V, 3.3V) are generated directly on the MicroZed board.
The board will draw approximately 1.2A from the 5V supply.
Reset
The Zynq7000 has a power-on reset pin (PS_POR_B). The corresponding net designator on the MicroZed board is PG_MODULE. The signal is available on J2 (pin 11). Tie this pin to '0' with a push button to reset the whole board. This reset will also sample the state of the mode jumpers on the MicroZed board which determine the boot mode.
ADC
The MicroZed board doesn't incorporate an ADC. Please refer to Adapter für Microzed Board for connecting an external ADC128S102 (general purpose, 8 channels) or a AD7476 (1 channel, for IR distance sensors).
