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 and Tibbo BASIC Manual").
- Based on a high-performance purpose-built 88-MHz T1000 ASIC
- 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)
- 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
- 2KB EEPROM for data storage
- Up to 32 general-purpose I/O lines. 8 interrupt lines, Serial port lines, 24 lines that are combined into three 8-bit ports
- Square wave output (6Hz - 22'1184MHz), which can be used to control external buzzer.
- Supports external LCD and keypad
- Four control lines for status LEDs (2 lines for green and red status LED control; 2 lines for Ethernet status LED control)
- Software- controlled onboard PLL to select the clock frequency of the device: 11.0592MHz with PLL off, 88.4736MHz with PLL on
- Reliable power-on/ brown-out reset circuit; no additional external reset circuitry required. Master reset input also provided
- Power: 230mA @ 3.3V (100BaseT mode, PLL on)
- Dimensions: 17.1x19.1x14.6mm.
- Tibbo BASIC application can be debugged through the network and no additional debugging hardware, such as in-circuit emulator, is required.
- Firmware and Tibbo BASIC application are upgradeable through the serial port or network.
