EM2000 BASIC/C-programmable IoT Module

em2000

Introduction

The EM2000 is Tibbo's fastest, as well as the most powerful and versatile BASIC/C-programmable IoT module. The module is a high-performance upgrade to our popular EM1000 device.

The module's hardware features include 100/10BaseT Ethernet port, four serial ports supporting UART, Wiegand, and clock/data modes, four I2C/SPI ports, onboard flash, EEPROM, RTC, and up to 56 I/O lines.

The EM2000 is also excellent for prototyping your projects — it has the standard pin pitch of 2.54mm (0.1").

The EM2000 is fully supported by Tibbo IDE software and a dedicated EM2000 platform that covers all hardware facilities of the module (see "TIDE and Tibbo BASIC Manual"). For convenient testing and evaluation Tibbo offers EM1000TEV and EM1000EV development systems (they are compatible with the EM2000 module). The EM2000 can also support Wi-Fi and GPRS communications.

EM2000 advantages over the EM1000 module

The EM2000 is a high-performance upgrade to our EM1000 device. Here is small list of important improvements:

•32-bit architecture (vs. 16-bit architecture of the EM1000).

•5 to 80 times better performance, depending on the calculations and variable types.

•7 times faster GPIO manipulation.

•3 times larger available user SRAM (66KB vs. 22KB).

•1.5-3.0 times faster graphics.

•2.2 times lower power consumption (100mA vs. 220mA).

•2 times larger flash memory (1MB for TiOS/code + 1MB for the file system vs. 1MB total for TiOS, code, and file system).

•56 I/O lines (vs. 54 lines on the EM1000).

•4-channel ADC.

•The ability to update TiOS firmware and compiled Tibbo BASIC/C app over-the-air (this requires the WA2000 and an iOS or Android device).

Hardware features

•32-bit architecture.

•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 the WA2000 add-on module to be connected).

•Optional BLE interface (requires the WA2000 add-on module).

•Can control a GPRS modem* (such as the SIM900).

•Four high-speed serial ports (CMOS-level):

  • Baudrates of up to 460,800bps;
  • None**/even/odd/mark/space parity modes;
  • 7**/8 bits/character;
  • Full-duplex mode with RTS/CTS and XON/XOFF flow control;
  • Half-duplex mode with direction control;
  • Encoding and decoding of Wiegand and clock/data streams.

•56 general-purpose I/O lines; 8 lines can work as interrupts.

•Square wave output (can be used for buzzer* control).

•4-channel ADC.

•4 synchronous serial ports with SPI and I2C modes.

•Supports a 320x240 TFT LCD*.

•Supports matrix and binary output keypads*.

•RTC with dedicated backup power input.

•66KB SRAM for Tibbo BASIC/C variables and data.

•1MB flash for TiOS and application code.

• Additional 1MB flash for the hardened fault-tolerant file system.

•2048-byte EEPROM for data storage.

•Three status LEDs onboard:

  • Green and red main status LEDs;
  • Yellow Ethernet link LED.

•Four control lines for external status LEDs:

  • Two control lines for green and red main status LEDs;
  • Two control lines for Ethernet "link" and "100Mb" LEDs.

•Software-controlled PLL allows selecting full, medium, or low speed.

•Reliable power-on/ brown-out reset circuit.

•Power: 100mA @ 3.3V (100BaseT mode, full speed).

•Dimensions (LxWxH): 38.4 x 28.4 x 5.5mm.

•Prototyping-friendly 2.54mm (100mil) pin pitch.

•Operating temperature range: -40 ~ +80 C.

•Firmware and compiled Tibbo BASIC/C app can be updated through:

oThe serial port;

oEthernet LAN; or

oOver-the-air (this requires the WA2000 and an iOS or Android device).

•Tibbo BASIC/C application can be debugged through the Ethernet LAN (no additional debugging hardware is required).

•CE- and FCC-certified.

\ Must be connected externally.*

\* The EM2000 does not support the combination of 7 bits/character mode and the "none" parity mode.*
