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).
- 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.
