While occupying miniscule 19x17mm on your PCB, the EM1202 BASIC-programmable embedded module retains most features of the much larger 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 external LCD, keypad, buzzer, and card readers.

Thanks to its miniature dimensions, the EM1202 can be conveniently used as a network front-end in automation, security, and data collection systems.

The EM1202 can also support Wi-Fi communications (this requires GA1000 add-on board).

Specifications:

• 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.
• 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: 17.1×19.1×14.6mm.
• Firmware is upgradeable through the serial port or network.
