EM1206 BASIC-programmable Ethernet Module

EM1206 BASIC-programmable Ethernet Module

The EM1206 is a miniature BASIC-programmable embedded module. In combination with the RJ203 jack/magnetics, the EM1206 occupies only 34.5×19 mm of board space. Alternatively, the EM1206 can be used with any suitable magnetics and jack.

The module’s hardware mix, which includes 100Base/T Ethernet, four serial ports, flash disk, EEPROM, and RTC, has been carefully tailored to address the typical needs of network-enabled control applications.

This makes the EM1206 especially suitable for “connected” edge products such as sensors, network-enabled card readers, actuators, and other lightweight devices.

The EM1206 can also support Wi-Fi communications (this requires GA1000 add-on board), as well as external LCD, keypad, and buzzer.

The EM1206 can be ordered standalone or in combination with the RJ203 module.

  • Based on a high-performance purpose-built 88-MHz ASIC (T1000).
  • 10/100BaseT auto-MDIX Ethernet port (no magnetics).
  • Optional Wi-Fi interface (requires GA1000 add-on module).
  • Four high-speed serial ports (CMOS-level):

                        Baudrates of up to 921,600bps;

                        None/even/odd/mark/space parity modes;

                        7/8 bits/character modes;

                        Full-duplex mode with optional flow control;

                       Half-duplex mode with direction control;

                       Encoding and decoding of Wiegand and clock/data streams.

  • Up to 1024KB flash memory for firmware, application, and data.
  • 2KB EEPROM for data storage.
  • RTC with backup power input.
  • Supports external keypad.
  • Programmable square-wave output for external buzzer.
  • Up to 17 general-purpose I/O lines (including 8 interrupt lines).
  • Control lines for two external status LEDs.
  • Four status LEDs onboard:

                       Green and red status LEDs;

                       Green and yellow Ethernet status LEDs.

  • Software-controlled onboard PLL.
  • Reliable power-on/brown-out reset circuit.
  • Power: 230mA @ 3.3V (100BaseT mode, PLL on).
  • Dimensions: 33.2x18.1x5.5mm.
  • Firmware is upgradeable through the serial port or network.
