At only 19x17mm, the EM1202 is no larger than a standard RJ45 jack! Four serial ports, 32 I/O lines, onboard flash and EEPROM, optional Wi-Fi.

10/100BaseTEthernet port 1024KB flash disk onboard
Four high-speed TTL serialports Supports Wi-Fi,LCD, keypad, buzzer
Up to 32 I/O lines Very compact (19x17x14mm)


While occupying miniscule 19x17mm on your PCB, the EM1202BASIC-programmable embedded module retains most features of the muchlarger EM1000 device.

These include 100Base/T Ethernet, four serial ports, onboard flash,EEPROM, and 32 I/O lines that can be used to interface with externalLCD, keypad, buzzer, and card readers.

Thanks to its miniature dimensions, the EM1202 can be convenientlyused as a network front-end in automation, security, and datacollection systems.

The EM1202 can also support Wi-Fi communications (this requiresGA1000 add-on board).


  • 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-onmodule).
  • 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.
  • Supports external LCD and keypad.
  • Programmable square-wave output for external buzzer.
  • Up to 32 general-purpose I/O lines (including 8 interrupt lines).
  • Four control lines for status LEDs.
  • Software-controlled onboard PLL.
  • Reliable power-on/brown-out reset circuit.
  • Power: 230mA @ 3.3V (100BaseT mode, PLL on).
  • Dimensions: 17.1x19.1x14.6mm.
  • Firmware is upgradeable through the serial port or network.


    Platform objects:
  • Sock — socket comms (up to 16 UDP, TCP, and HTTP sessions).
  • Net — controls Ethernet port.
  • Wln — handles Wi-Fi interface (requires GA1000 add-on module).
  • Ser — up to 4 serial ports (UART, Wiegand, and clock/data modes).
  • Io — handles I/O lines, ports, and interrupts.
  • Lcd — controls graphical display panels (several types supported).
  • Kp — scans keypads of matrix and "binary" types.
  • Fd — manages flash memory file system and direct sector access.
  • Stor — provides access to the EEPROM.
  • Romfile — facilitates access to resource files (fixed data).
  • Pat — "plays" patterns on up to five LED pairs.
  • Beep — generates buzzer patterns.
  • Button — monitors MD line (setup button).
  • Sys — in charge of general device functionality.

Function Groups: String functions (21 in total!),date/time conversion functions, and hash calculation functions (md5 andsha1).

Variable Types: Byte, char, integer (word), short,dword, long, real, string, plus user-defined arrays and structures.
