WIZ850IO

products:wiz850io:start [Document Wiki] Page 1 of 5 Document Wiki WIZ850io Overview WIZ850io is a compact size network module that includes a W5500 (TCP/IP hardwired chip and PHY embedded), a transformer and RJ45. It can be used as a component and no effort is required to interface W5500 and Transformer. The WIZ850io is an ideal option for users who want to develop their Internet enabling systems rapidly. WIZ850io is hardware compatible with WIZ820io. WIZ820io users, to migrate to WIZ850io, need to modify the Firmware. For the detailed information on implementation of Hardware TCP/IP, refer to the W5500 Datasheet. Hardware Specification WIZ850io • • • • • • • • Plugin Network Module. Hardware compatible with WIZ820io. Usable without H/W design for W5500, Transformer & RJ45. Fast evaluation for W5500 & MCU in the target board. Support high speed SPI interface. Support power down mode and Wake-on-LAN function Very small form factor : 23mm x 25mm x 18mm 1 x 6, 2.54mm Pin Header x 2 Pin Out http://wizwiki.net/wiki/doku.php?id=products:wiz850io:start 8/22/2018 products:wiz850io:start [Document Wiki] Page 2 of 5 Pin Description Pin No. J1 Pin Type Description 1 P GND Ground 2 P GND Ground 3 I MOSI SPI Master Out Slave In This pin is used for SPI MOSI signal pin 4 I SCLK SPI Clock This pin is used for SPI Clock Signal pin 5 I SCNn SPI Slave Select This pin is used for SPI Slave Select Signal Pin when using SPI interface 6 I INTn W5500 Interrupt : Low activity This pin is used for indicating event like socket TCP connection, disconnection, data receiving timeout, WOL(Wake on Lan) and so on occurred in W5500 inside WIZ550io. The interrupt is cleared by writing IR register or Sn_IR. All interrupts are maskable. Pin No. J2 Pin Name Pin Type Pin Name Description 1 P GND Ground 2 P 3.3V Power : 3.3V power supply 3 P 3.3V Power : 3.3V power supply 4 - NC Not Connect 5 I RSTn Reset : Low activity Hold at least 500us after asserted to LOW and keep HIGH until next Reset needed. 6 O MISO SPI Master In Slave Out This pin is used for SPI MISO signal pin User need to wait for 50ms after this pin is changed to HIGH to communicate with WIZ850io.
