About

While occupying miniscule 19x17mm on your PCB, the EM1202 BASIC-programmable embedded module retains most features of the much larger EM 1000 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 EM 1202 can also support Wi-Fi communications (this requires GA1000 add-on board).

Specifications

• Based on a high-performance purpose-built     2KB EEPROM for data storage.

88-MHz ASIC (T1000)                                              .      Supports external LCD and keypad
