X-NUCLEO-PLM01A1 Power line communication expansion board based on ST7580 for STM32 Nucleo Data brief Description The X-NUCLEO-PLM01A1 expansion board for STM32 Nucleo is based on the ST7580 FSK, PSK multi-mode power line networking system- on-chip. It provides an affordable and easy-to- use solution for the development of connectivity applications based on power line communication. It lets you easily evaluate the communication features of the ST7580 based on a DC two-wire link between two boards. You can also perform evaluation on an AC power line by connecting the X-NUCLEO-PLM01A1 to an STEVAL-XPLM01CPL board providing effective AC coupling and isolation. The X- NUCLEO-PLM01A1 is interfaced with the STM32 Features controller via UART and GPIO pins and is STM32 Nucleo expansion board based on compatible with the Arduino UNO R3 (default the ST7580 power line networking system- configuration) and ST morpho (optional, not on-chip mounted) connectors. ST7580 main characteristics: FSK, PSK modem for robust wireline communication up to 28.8 kbps 8-18 V analog supply voltage 3.3 V digital supply Output transmitted signal capability up to 14 Vp-p, 1 Arms Frequency range 9-250 kHz TX and RX filters on board optimized for the CENELEC B (95-125 kHz) frequency band, suitable for IoT / Smart Home / Smart City applications Compatible with STM32 Nucleo boards Equipped with Arduino UNO R3 connectors Example firmware available for point-to-point communication, compatible with STM32Cube firmware RoHS compliant June 2017 DocID030444 Rev 1 1/6 www.st.com For further information contact your local STMicroelectronics sales office Schematic diagrams X-NUCLEO-PLM01A1 1 Schematic diagrams Figure 1: X-NUCLEO-PLM01A1 schematic (1 of 3) T REQ BR1 BR0 RESERVED1 RESERVED2 RESERVED3 VDDIO SCLK0 2/6 DocID030444 Rev 1 10K R23 TXD VDDIO 10K R30 TCK VDDIO VDDIO 10K R9 RESERVED0 VDDIO VDDIO R47 10K DL1 LED-GREEN VDDIO RN2 RN3 PL TX ON1 2 R31 560R 10K 10K C32 DL2 LED-RED 100nF/25V PL RX ON1 2 R32 560R RESERVED1 RESERVED2 RESERVED3 PL RX ON BR1 U2 BR0 PL TX ON TXD 1 36 TXD CL SEL VDDIO RXD 2 35 VDDIO RXD VSSA 3 34 VDDIO VDDIO 4 33 C10 TRSTN GND 5 32 TMS NC 32 6 31 RESERVED0 100nF/25V GND RESERVED0 TCK 7 30 ST7580 TCK NC 30 8 29 VDDIO TDO NC 29 9 28 TDI VDDIO PLC RESETN 10 27 VDD REG 1V8 RESETN VDD REG 1V8 11 26 PA OUT VDD VDD PA OUT 12 25 XIN VSS Y3 FB1 VSSA VSS 8MHz BLM21PG331SN1 VDD PLL VCC C21 C8 10uF/25V R11 100nF/25V 91R TP1 VCCA ZC C28 C27 10uF/10V 100nF/25V 5 4 6 3 7 2 8 1 5 4 6 3 7 2 8 1 C35 100nF/25V C34 C31 100nF/25V 4.7uF/4V C30 8MHZ MCO 100nF/25V C29 100pF/C0G 13 48 XOUT RESE RVED5 14 47 GND RESE RVED4 15 46 VSSA VDD 16 45 VDD PLL GND 17 44 VCCA RESE RVED3 18 43 ZC IN ZC IN RESE RVED2 19 42 RX IN RX IN RX IN RESE RVED1 20 41 TX OUT TX OUT TX OUT PL TX ON PA IN+ 21 40 PA IN+ PA IN+ BR0 PA IN- 22 39 PA IN- PA IN- BR1 CL 23 38 CL T REQ VCC 24 37 VCC PL RX ON 49 EP PA OUT C13 100nF/25V C14 10uF/6.3V C11 100nF/25V C12 10uF/6.3V
