EM1001 BASIC/C-programmable IoT Board
|Top Previous Next|
The EM1001 is a BASIC-programmable Ethernet board. The EM1001 is a close relative of the EM1000 Ethernet module. Two devices have the same feature set, including the 10/100BaseT Ethernet port, four serial ports, onboard flash disk, EEPROM, and the RTC with optional backup supercapacitor. Like the EM1000, the EM1001 board can control a GA1000 Wi-Fi add-on, as well as an external LCD, keypad, buzzer, and many other peripheral components.
Unlike the EM1000, the EM1001 us a self-sufficient board: it has a 12V-to-3.3V switching power regulator, RJ45 connector with magnetics, three LEDs, and the MD button. Thus, the EM1001 does not require a host board to plug into. The EM1001 is the host board. As such, the EM1001 is equally suited to low-volume production devices and hobbyist projects alike.
The EM1001 is fully supported by TIDE software. The board shares the same platform with the EM1000 module (see "TIDE and Tibbo BASIC Manual").
•Based on a high-performance purpose-built 88-MHz T1000 ASIC.
•10/100BaseT auto-MDIX Ethernet port with RJ45/magnetics (MDIX feature means automatic detection of "straight" and "cross" cables).
•Optional Wi-Fi interface (requires the GA1000 add-on module).
•Optional GPRS connectivity with the use of an external GPRS module (such as the SIM900).
•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.
•1024KB flash memory for firmware, application, and data storage.
•2KB EEPROM for data storage.
•RTC with an optional onboard supercapacitor.
•Up to 54 general-purpose I/O lines. Among them:
- 8 interrupt lines;
- Serial port lines;
- 40 lines that are combined into five 8-bit ports;
- Square wave output (6Hz - 22'1184MHz), which can be used to control an external buzzer.
•Supports external LCD and keypad.
- Green and red status LEDs;
- Yellow Ethernet status LED.
•Control lines for external green and red status LEDs.
•RST and MD control lines.
•Software- and hardware-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.
- Through the switching power regulator: 8-20V supplied via the power jack or VIN line;
- Direct 3.3V power: regulated 3.3V supplied via the 3.3V line.
•Available current: when powered through the switching regulator, the EM1001 can supply up to 1A of power through its 3.3V pin (1.3A without the GA1000).
•Dimensions: 75x36x17.5mm (not including protruding RJ45 and power jack; GA1000, when installed, adds 1.5mm to the combined device height).
•Firmware and Tibbo BASIC/C application are upgradeable through the serial port or network.
•Tibbo BASIC/C application can be debugged through the network and no additional debugging hardware (such as a JTAG board) is required.
•Variable Types: Byte, char, integer (word), short, dword, long, real, string, plus user-defined arrays and structures.
•Function Groups: string functions (27 in total!), date/time conversion functions (8), encryption/hash calculation functions (AES128, RC4, MD5, SHA-1), and more.
