Features
10/100BaseT Ethernet port
1024KB fl ash disk onboard
Four high-speed TTL serial ports
Supports Wi-Fi, LCD, keypad, buzzer
Up to 32 I/O lines
Very compact (19x17x14mm)
About
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 fl ash, 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 fl ow control;
Half-duplex mode with direction control;
Encoding and decoding of Wiegand and clock/
data streams.
Up to 1024KB fl ash memory for fi rmware,
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.
