1. Introduction

WIZ812MJ is the network module that includes W5100 (TCP/IP hardwired chip, include PHY), MAG-JACK (RJ45 with X’FMR) with other glue logics. It can be used as a component and no effort is required to interface W5100 and Transformer. The WIZ812MJ is an ideal option for users who want to develop their Internet enabling systems rapidly. For the detailed information on implementation of Hardware TCP/IP, refer to the W5100 Datasheet. WIZ812MJ consists of W5100 and MAG-JACK.

TCP/IP, MAC protocol layer: W5100

Physical layer: Included in W5100

Connector: MAG-JACK(RJ45 with Transformer)

1.1. Features Supports 10/100 Base TX

Supports half/full duplex operation

Supports auto-negotiation and auto cross-over detection

IEEE 802.3/802.3u Compliance

Operates 3.3V with 5V I/O signal tolerance

Supports network status indicator LEDs

Includes Hardware Internet protocols: TCP, IP Ver.4, UDP, ICMP, ARP, PPPoE, IGMP

Includes Hardware Ethernet protocols: DLC, MAC

Supports 4 independent connections simultaneously

Supports MCU bus Interface and SPI Interface

Supports Direct/Indirect mode bus access

Supports Socket API for easy application programming

Interfaces with two 2.54mm pitch 2 x 10 header pin

Temperature :

[PCB rev1.0] : 0 ~ 70℃ (Operation), -40 ~ 85℃ (Storage)

[PCB rev1.1] : -40 ~ 85℃ (Operation), -40 ~ 85℃ (Storage)

1.3. Difference between WIZ811MJ and WIZ812MJ

WIZ811MJ WIZ812MJ

Two 2.54mm pitch 10x2 header

The same pin-header is mounted but pin description is different J2:9 GND -> RX_LED J2:10 GND -> TX_LED J2:19 GND -> /LINKLED

Two PCB Through Hole(Ø 3.00mm) Four PCB Through Hole(Ø 3.00mm)

55.5 x 25 x 23.5mm (W x H x D) The same size

LINKLED : Active low in link state indicates a good status for 10/100M. It is always ON when the link is OK and it flashes while in a TX or RX state.

/LINKLED : Active low in link state indicates a good status for 10/100M. It is always ON when the link is OK. It does not flashes while in a TX or RX state.

ACT_LED : Active low in active state indicates a good status for 10/100M. It is always ON when the link is OK and it flashes while in a TX or RX state.

2.3. MCU Interfaces

Symbol Type Pin No. Description

SCLK I J2:3 SCLK(Serial Clock) This pin is used to SPI Clock Signal pin.

/SCS I J2:4

/SCS (Slave Select) * This pin is used to SPI Slave Select signal Pin. This pin controls SPI_EN signal of W5100. When /SCS signal assert low, W5100 drive SPI mode by SPI_EN signal toggled high.

MOSI I J1:1 MOSI (Master Out Slave In) * This pin is used to SPI MOSI signal pin.

MISO I/O J1:2 MISO (Master In Slave Out) * This pin is used to SPI MISO signal pin.

A14~A8 I J1:13 ~ J1:19

Address Used as Address[14-8] pin

A7~A0 I J2:11 ~ J2:18 Address Used as Address[7-0] pin

D7~D0 I/O J1:3 ~ J1:10 Data 8 bit-wide data bus

/CS I J2:7 Module Select : Active low. /CS of W5100

/RD I J2:6 Read Enable : Active low. /RD of W5100

/WR I J2:5 Write Enable : Active low /WR of W5100

/INT O J2:8

Interrupt : Active low After reception or transmission it indicates that the W5100 requires MCU attention. By writing values to the Interrupt Status Register of W5100 the interrupt will be cleared. All interrupts can be masked by writing values to the IMR of W5100 (Interrupt Mask Register). For more details refer to the W5100 Datasheet

2.4. Miscellaneous Signals Symbol Type Pin No. Description

/RESET I J2:2

Reset : This pin is active low input to initialize or re-initialize W5100. By asserting this pin low for at least 2us, all internal registers will be re-initialized to their default states.

RX_LED O J2:9 RX_LED : Receive activity LED Active low indicates the presence of receiving activity.

TX_LED O J2:10 TX_LED : Transmit activity LED Active low indicates the presence of transmitting activity.

/LINKLED O J2:19

LINKLED : Active low in link state indicates a good status for 10/100M. It is always ON when the link is OK. It does not flashes while in a TX or RX state.
