EM1202 BASIC/C-programmable Ethernet
Module
NOT RECOMMENDED FOR NEW DESIGNS
Introduction
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 24 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 is fully supported by TIDE software and a dedicated EM1202 platform
that covers all hardware facilities of the module (see TIDE, TiOS, Tibbo BASIC, and
Tibbo C Manual). For convenient testing and evaluation Tibbo offers EM1202EV
evaluation board. The EM1202 can also support Wi-Fi communications (this requires
GA1000 add-on board).
Hardware features
·
Powered by Tibbo OS (TiOS).
·
10/100BaseT auto-MDIX Ethernet port (automatic detection of "straight" and
"cross" cables). Standard Ethernet magnetics are NOT integrated into the module.
·
Optional Wi-Fi interface (requires GA1000 add-on module to be connected).
·
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.
·
512K or 1024KB flash memory for firmware, application, and data storage.
