EM1206 in combination with the RJ203
Introduction
The EM1206 is a miniature BASIC-programmable embedded module. This device is a
member of the x20x family of embedded modules and takes full advantage of unique
mechanical concept of x20x devices. The module can be used with any suitable jack
and magnetics, or with our patent-pending RJ203 jack/magnetics module. The
combined PCB footprint of the EM1206 and RJ203 is only 34.5x19mm.
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 is fully supported by TIDE software and a dedicated EM1206 platform
that covers all hardware facilities of the module (see TIDE, TiOS, Tibbo BASIC, and
Tibbo C Manual). For convenient testing and evaluation Tibbo offers the EM1206EV
evaluation board. The EM1206 can also support Wi-Fi communications (this requires
WA2000 add-on module), as well as external LCD, keypad, and buzzer.
Hardware features
·
Powered by Tibbo OS (TiOS).
·
10/100BaseT auto-MDIX Ethernet port (automatic detection of "straight" and
"cross" cables). Standard Ethernet magnetics are NOT integrated into the module:
- Connect any suitable external jack and magnetics; or
- Combine the EM1206 with the RJ203 jack/magnetics front end to achieve minimal
PCB footprint.
·
Optional Wi-Fi interface (requires the WA2000 add-on module to be connected).
·
Can control a GPRS modem* (such as the SIM900).
·
Four high-speed serial ports (CMOS-level):
- Baudrates of up to 921,600bps;
- None/even/odd/mark/space parity modes;
- 7/8 bits/character;
- Full-duplex mode with RTS/CTS and XON/XOFF flow control;
- Half-duplex mode with direction control;
- Encoding and decoding of Wiegand and clock/data streams.
·
17 general-purpose I/O lines; 8 lines can work as interrupts.
·
Square wave output (can be used for buzzer* control).
·
4 synchronous serial ports with SPI and I2C modes.
