Hardware Specification
Pin-out v1.0
The pins below are fixed functions in surf 5
| I/O | Pin Name | Description |
|---|---|---|
| O | PC_15 | Connected to user LED |
| O | PC_10 | UART2_TX connected USB to Serial IC |
| I | PC_11 | UART2_RX connected USB to Serial IC |
| O | PA_03 | SWCLK connected J3 |
| IO | PA_04 | SWDIO connected J3 |
Apart from GPIO and ground pins, there are 5 other pins on the main 40-pin interface:
| Pin No. | Pin Name | Description |
|---|---|---|
| PIN40 | VBUS | Micro-USB input voltage, connected to micro-USB port pin 1. Nominally 5V. |
| PIN39 | VSYS | Main system input voltage, which can vary in the allowed range 4.3V to 5.5V, and is used by the on-board LDO to generate the 3.3V . |
| PIN37 | 3V3_EN | Connects to the on-board LDO enable pin. To disable the 3.3V (which also de-power Surf 5), short this pin low. |
| PIN36 | 3V3 | Main 3.3V supply to W7500 and IP101GRI, generated by the on-board LDO. |
| PIN30 | RUN | Reset pin, To reset W7500, short this pin low. |
Operation Condition
| Item | Description |
|---|---|
| Operation Temperature MAX | 70C (including self-heating) |
| Operation Temperature MIN | -20C |
| VBUS | DC 5V (+/- 10%) |
| VSYS Min | DC 4.3V |
| VSYS Max | DC 5.5V |
Recommended maximum ambient temperature of operation is 50C.
Power Consumption
The power comsumption of Surf5 depends on how much user use the peripheral in what temperature environment.
We measured power consumption by running TCP Server Loopback example code in a 25 degree environment.
| Current(A) | Voltage(V) | |
|---|---|---|
| AVR | 0.059 | 5V (VBUS) |
| MIN | 0.057 | 5V (VBUS) |
| MAX | 0.061 | 5V (VBUS) |
If you're planning to use a low-powered application, it's a good idea to test your code before mass production.
