    1. Introduction to SG8V1 Easy

 

   SG8V1 microcontroller was researched, designed by Integrated Circuit Design Research & Education Center - ICDREC. This is the first commercial microcontroller of Vietnam officially offered in the market. Chip is applied in the field of electricity, electronics, information technology ... with technical features, performance is completely competitive with imported chips of the same type.

   SG8V1 Easy is a product designed by AT-COM gives utility users the combination ATCBus with SG8V1 microcontroller series of ICDREC. The board supports USB Full Speed V2.0 through a programming kit that allows users to directly load the firmware for the SG8V1 microcontroller without any other programming kit. In addition, the microcontroller combines the Dual ATCBus Host Socket design to maximize the microcontroller resources that meet the needs of programmers deploying applications such as GSM, GPRS, GPS, Wifi, Ethernet, USB, PWM ... Especially with convenient data output, SG8V1 Easy will bring the most modern and refined design inspiration.

  3. Features of SG8V1 Easy 

  • Power supplies for SG8V1 Easy are available through the following connection ports:

              - 5VDC via USB mini connector (5).

              - 5VDC via Terminal Connector (7).

              - 3.7V Li-Po battery through Connector (10).

  • The remarkable feature of the SG8V1 Easy is its design backup online, which can switch between 5VDC and battery power for mobility and continuous operation in the event of a power failure.
  • This feature is based on the TPS61092 IC Boost Converter with the input voltage of 1.8 - 5.5V and the output current that meets the application need current up to 2A.

 

  • Battery for the board is Lithium - Polymer 3.7V rechargeable battery and recharged from 5VDC power via MCP73832T charging IC with 4.2V charging voltage and 100mA charging current, fully automatic charging mode to maximize the longevity of Battery.
  • The charger also has a function is charging battery status indicator through Charging LED Indicator(9), while charging the Led light is red when the battery is fully charged, Led off.
  • Low battery indicator function is also integrated is displayed through Low Battery LED Indicator (12). When the voltage of the battery drops below 3.3V, the Led light is red. 
  • The board is integrated ON / OFF switch, the user can set the switch to ON or OFF to open or shut down the power for the circuit. In addition, users can connect to the external switch via External ON / OFF Switch (3).

 

  • The board is built-in to the SG8V1 chip, and users need only connect to a computer via the USB mini port so they can directly load the application onto the SG8V1 chip without having to use any other programming kit. The central processor chip is also an SG8V1 chip.

  • SG8V1 Easy integrates a powerful SG8V1 microcontroller with a 12 MHz quartz crystal, 64K x 16 program memory, 3Kb data memory and 16Kb RAM combine with the Dual ATCBus Host Socket optimized peripheral of microcontroller allows SG8V1 Easy to easily combine multiple ATCBus boards to perform applications such as GSM, GPRS, GPS, etc.

  • The board is equipped with a reset button, two blue LEDs, two push buttons, all located at the bottom of the board:

           - The reset button is used to reset the SG8V1 microcontroller, when the reset button is pressed, the voltage at the MCLR pin of SG8V1 changes from logic 1 to logic 0.

           - 2 Led blue visual indicators or in case users need to debug code when programming. 2 Led connected to SG8V1 via pins PA7 and PA6, positive when the output of PA7, PA6 at logic level 1.

           - When the push button action changes the pins PA5, PD2 of the SG8V1 from logic 1 to logic 0.

  

  • The board is designed with a header with the I/O of SG8V1 placed along the sides of the SG8V1 Easy. 

 

  • The Dual ATCBus Host Socket with Analog, SPI, I2C, Timer, PWM, UART, ..., ATCBus compliant pins helps users connect to the Easy Board to experience "Plug and Play" feature of SG8V1 Easy
