4 4 INTERFACES 1 Features based on the HomePlug Green PHY PLC-Chip QCA7000 suitable for direct connection to mains/powerline integrated AC isolation external 3.3 V power supply GPIO / UART / SPI / CAN-Interface usable as remote I/O customer programmable microcontroller 2 Abstract The PLC (PowerLine Communication) module provides the connectivity of any one of several serial interfaces via power line. Both point-to-point and multi-point connections are possible. The data will be transmitted as TCP/IP packets over the power line. The special feature of the module is that it can run without any additional hardware on the powerline. The module has TTL level serial interfaces. The galvanic isolation from the power line is done on the module. The QCA7000 from Qualcomm guarantees the compatibility with many other commercial powerline devices. Parameter Value Power supply 3.3 V (5V tolerant I/O) Power consumption 0.5 W Data rate max. 10 MBit/s Reach maximal 300 m over the Powerline Temperature range -40 C C Outline dimension 65 mm x 30 mm x 11 mm Weight 15 g RoHS PLC-Stamp 1 is manufactured RoHS compliant. 3 Applications interconnection of household appliances to the Smart Grid connecting smart meters to Smart Meter Gateways and/or LAN 1 /WAN 2 /Wifi connecting sensors connecting photovoltaics connecting heating and air conditioning coupling of machines and measurement devices forwarding of digital Signals (remote I/O) coupling of RF-cells for home automation 4 Interfaces Powerline: 230 V AC, 110 V AC, DC, dead-wire 2-wire-connections Serial interfaces: UART, SPI or CAN (only one interface active at any one time) Debug interface: SWD (serial wire debug) 1 Local Area Network 2 Wide Area Network 4/14

7 GETTING STARTED 7 Getting started An easy way to put PLC-Stamp 1 into operation is to link two of them with each other. So two user electronics can be coupled via powerline.

If you are not sure that your PLC-Stamp 1 have the same NMK, please use the push button simple connect function.

9 7 GETTING STARTED 7 Getting started An easy way to put PLC-Stamp 1 into operation is to link two of them with each other. So two user electronics can be coupled via powerline. Devices that share the same NMK (Network Membership Key) will form a logical network when connected to common powerline media. If you are not sure that your PLC-Stamp 1 have the same NMK, please use the push button simple connect function. Press the simple connect pushbutton (S1) on one of the PLC-Stamp 1 for less than 3 seconds. Press the simple connect pushbutton (S1) on the other PLC-Stamp 1 connected to the same medium for less than 3 seconds. Wait a few seconds for the two devices to form a network. This function will shown with a flashing LED5 while forming the network. When the LED is steady on the process was successful. For removing a PLC-Stamp 1 from a network you can use the same simple connect pushbutton function with pressing the button only at the PLC-Stamp 1 that has to be removed. The firmware for the QCA7000 is already loaded in production. The firmware for the MK20 has to build up from user. I2SE delivers a set of software libraries and program examples to make it easy to realize your software application. For debugging and flashing you can use the serial wire debug (SWD) interface. The picture shows how you can connect the SWD port with a simple pin header. 9/14

9 MODULE PINOUT 8 MAC addresses Each PLC-Stamp 1 gets two successive MAC addresses from I2SE. The first is for the QCA7000 and the second is for the MK20 controller.

10 9 MODULE PINOUT 8 MAC addresses Each PLC-Stamp 1 gets two successive MAC addresses from I2SE. The first is for the QCA7000 and the second is for the MK20 controller. The MAC addresses are printed on a label on PLC-Stamp 1. If you want to use your own MAC addresses it is possible to change them. Please note, that each firmware for the MK20 has to get it s own MAC address. (see software documentation) The labels are printed as in the following image: 9 Module pinout 9.1 Mains connector (X1) Name Type Function L Mains Powerline connection N Mains Powerline connection Typ: WAGO 2060 Series Conductor size: mm 2 strip length: 6-7 mm AWG: SMD-Pad connector (X2) Pin No. Name Type Function 1 GND PWR Supply voltage 2 N I RESET (MK20) 3 N I/O SWD DIO 4 N I SWD CLK 5 VDD PWR Supply voltage SWD - Serial Wire Debug 10/14

10.3 Safety and insulation rated parameters 13 SECURITY 10.3 Safety and insulation rated parameters The creepage and clearance distances between mains and client side are 5.5 mm.

12 10.3 Safety and insulation rated parameters 13 SECURITY 10.3 Safety and insulation rated parameters The creepage and clearance distances between mains and client side are 5.5 mm. The creepage distance between mains and client side in inner layers is 2.0 mm. In the area of the planar transformer we have the following layer construction: 11 MK20 Host-Controller Freescale MK20DX256VMC7 ARM Cortex M4 256kByte Flash 32kByte FlexNVM 64kByte RAM 2kByte EEPROM/FlexRAM 72MHz internal clock For programming and debugging the SWD (serial wire debug) interface is connected to the SMD-Pad connector. For more information please contact Freescale. 12 Software The QCA7000 software will be programmed in the flash already so that you can start using it right away but the module is shipped with no software in the microcontroller. To use the board you will have to write your own firmware. You can get started by using firmware examples and libraries that are available in the Web Support page for the PLC-Stamp 1. This way you can implement your own protocols using UART, SPI, CAN or simply GPIO. 13 Security The Network Membership Key (NMK) that is used for forming a logical network is 50:D3:E4:93:3F:85:5B:70:40:78:4D:F8:15:AA:8D:B7 (Cleartext: HomePlugAV). This key can be changed by using I2SE libmme from your microcontroller. This library can be found on the Web Support page. The Device Access Key (DAK) that restricts access to critical device functions has a default value of 68:9F:07:4B:8B:02:75:A2:71:0B:0B:57:79:AD:16:30 (Cleartext: HomePlugAV) for all units unless it is otherwise noted. You can not change this Key. For highest security it is recommended that each device has a different DAK. 12/14

15 ERRATA 14 Order Information There are two versions of this product available: Version name Features Availability Variant 1 all described above standard Variant 2 as Variant 1 but misses DIP

13 15 ERRATA 14 Order Information There are two versions of this product available: Version name Features Availability Variant 1 all described above standard Variant 2 as Variant 1 but misses DIP switches (DIP 1 and DIP 2), push button (S1) and LEDs (LED1-LED4) on request 15 Errata Table 1 shows which units of PLC-Stamp 1 are affected by which issue. Batch Issue Numbers MAC 00:01:87:04:00:00 to MAC 00:01:87:04:01:8f 1, 2, 3, Issue 1: Hickup Issues Table 1: Issues per batch When the 3.3 V power supply collapses for a short period of time the MK20 processor might lock up. To prevent this you should enable the Low Voltage Detection Reset (register LVDRE = 1) and set the Low Voltage Detect Voltage to high (LVDV=01) Issue 2: Slow Power Up Ramp When the 3.3 V power supply ramps up slowly from 0 V (slower than 10 ms from 0 to 3.3V) the MK20 processor might not start correctly. You can fix this issue by cutting a trace between the QCA7000 and the MK20. This will have the side effect that you are no longer able to control the QCA7000 reset in your MK20 software. The trace that has to be cut to resolve this issue is between QCA7000 RESET L (Pin 5) and MK20 PTA4 (Pin J8) as shown as red trace on the green PCB in image figure 1. Carefully cut it anywhere in the makred area. Future releases of this product will have RESET L connected to pin PTA14 of the MK20 processor. Please be aware of that change if you plan to reset the QCA7000 via this pin. 13/14

14 15.3 Issue 3: Link Status always 1 16 CONTACT 15.3 Issue 3: Link Status always 1 Units affected by this issue are flashed with QCA7000 firmware Version MAC-QCA FINAL, which will cause the VS PL LNK STATUS MME to always report Link Up (0x01). The Issue can be resolved by replacing the original firmware by the version MAC-QCA FINAL or newer Issue 4: Temperature Range degraded Units that are effected by this issue will have a temperature rating below the original specification. The correct rating for this units is 0 C - 85 C. 16 Contact Website: I2SE GmbH Friedrich-Ebert-Str Leipzig Germany 14/14
