EM510 MiniMo® BASIC/C-Programmable IoT Module

Introduction

The EM510 MiniMo® device is a miniature standalone Tibbo BASIC/C-programmable embedded module, designed to be used in combination with a standard LED/magnetics RJ45 jack. The combined footprint of the EM510 and a standard RJ45 jack is only 28.5x18.5mm.

The module's hardware mix — which includes a 10/100BaseT Ethernet port, a serial port, and eight GPIO lines — has been carefully tailored to address the basic needs of lightweight IoT devices. If your application has a need to store data in files, an external flash IC can be connected to the EM510. By connecting the WA2000 add-on module to the EM510, you can also enable Wi-Fi and BLE (Bluetooth Low Energy) communications.

Compact dimensions, an innovative space-saving "vertical slice" mechanical design, low power consumption, and patented dual-function LED control lines make the module an excellent fit for miniature, cost-sensitive IoT designs.

The EM510 is fully supported by Tibbo IDE (TIDE) and a dedicated EM510 platform that covers all hardware facilities of the device. For convenient testing and evaluation, Tibbo offers the EM510EV development system.

The EM510 can be ordered standalone or in combination with an industry-standard RJ45 jack and other discrete components required to complete a working circuit.

EM510 Advantages Over the EM500

The EM510 is a higher-performance upgrade to our EM500 device. Here is a small list of important improvements:

• 32-bit architecture (vs. 8-bit architecture of the EM500)
• 17 to 33 times better performance, depending on the calculations and variable types
• Eight times faster GPIO manipulation
• 2.3 times lower power consumption (110mA vs. 260mA)
• Support for BLE (Bluetooth Low Energy) communications (this requires the WA2000)
• Support for WPA and WPA2 Wi-Fi security modes (Wi-Fi communications rely on the WA2000)
• SSI (SPI and I²C communications) object included
• The ability to update TiOS firmware and compiled Tibbo BASIC/C app over-the-air (this requires the WA2000)
• 20°C lower internal running temperature (52°C vs. 73°C)
• Industrial operating temperature range (–40°C to +85°C)

Hardware Features

• 32-bit architecture
• 10/100BaseT auto-MDIX Ethernet port (standard Ethernet magnetics are NOT integrated into the module)
• Optional Wi-Fi interface (requires the WA2000)
• Optional BLE (Bluetooth Low Energy) interface (requires the WA2000)
• One serial port (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
• 10 general-purpose I/O lines; two lines can work as interrupts
• 16.1KB SRAM for Tibbo BASIC/C variables and data
• 512KB flash memory for TiOS and application code (224KB for application code)
• Optional 1MB flash disk (requires an external SPI flash IC)
• 2,048-byte EEPROM (2,016 bytes are available for the application's data storage)
• Three control lines for status LEDs:
• Control lines for two external dual-function status LEDs
• A separate control line for the Ethernet link LED
• Reliable power-on/brown-out reset circuit (external reset IC not required)
• Power: 110mA @ 3.3V (100BaseT mode)
• "Vertical slice" form factor
• Dimensions (HxWxT): 16 x 18.5 x 6.5mm
• Operating temperature range: –40°C to +85°C
• Firmware and compiled Tibbo BASIC/C app can be updated through:
• The serial port
• Ethernet LAN
• Over-the-air (requires the WA2000)
• Tibbo BASIC/C application can be debugged through the Ethernet LAN (no additional debugging hardware is required)
• CE and FCC-certified

* The EM510 does not support the combination of 7 bits/character mode and the "none" parity mode.

Programming Features

The EM510 runs Tibbo OS (TiOS). The following is a list of the features supported by its programming platform:

• Objects:
• bt — in charge of the BLE (Bluetooth Low-Energy) interface
• button — monitors the MD (setup) line
• fd — manages the flash memory file system and direct sector access
• io — handles I/O lines, ports, and interrupts
• net — controls the Ethernet port
• pat — "plays" patterns on up to five LED pairs
• ppp — accesses the Internet over a serial modem (GPRS, etc.)
• pppoe — accesses the Internet over an ADSL modem
• romfile — facilitates access to resource files (fixed data)
• ser — controls the serial port (UART, Wiegand, clock/data modes)
• sock — socket comms (up to 16 UDP, TCP, and HTTP sessions)
• ssi — controls serial synchronous interface channels (SPI, I²C)
• stor — provides access to the EEPROM
• sys — in charge of general device functionality
• wln — handles the Wi-Fi interface
• Variable Types: Byte, char, integer (word), short, dword, long, real, string, plus user-defined arrays and structures
• Function groups: String functions, date/time conversion functions, encryption/hash calculation functions, and more
