XL2000 8051 MCU Development Board


  XL2000 is an integrated demo system for study and development of 8051 Microcontroller, which is provided with four functions of experimental instrument, programmer, simulation interface and ISP Download Cable. Enclosed with control CPU and combined with programming software which has independent intellectual property rights.

  With useful implemented peripherals, plentiful practical code examples and a broad set of additional add-on USB 2.0 IN-CIRCUIT ATMEL 8051 Development Board (Serial , Compact Flash, MMC/SD,ADC, DAC, RTC, RS-485, etc.).


The SN74LS47 are Low Power Schottky BCD to 7-Segment Decod-er/Drivers consisting of NAND gates 8 seven-segment digits in multiplex mode 16*16 led,The Graphic allows advanced visual messages to be displayed.
MMC/SD Card slot - For MMC/SD memory Cards. Used for data acquisition. RS-232 communication with PC or another microcontroller. D8155 - 2048-Bit Static MOS RAM with I/O Ports and Timer - Advanced Micro Devices
74hc14 Digital circuit chip 74hc165 Digital circuit chip 74hc164 Digital circuit chip
74hc138 Digital circuit chip 8-bit voltage AD converter for applications in measure - regulating devices. DAC - Digital - Analog Converter available for testing DA conversion
8 buttons are provided. DIP switch for separating port pins from Pull up or Pull down 4*4 buttons for program developing needs.
8 LED's are provided. 1 output lines with relays (up to 1A). Buzzer voice.(use DuPont wire can be connected to the arbitrary I/O port)
Real Time Clock DS1302 with battery supply. Infrared Remote Control Receiver Stepper Motor Driver
USB comm. connector for MCU with USB facilities. RS-485 communication for connecting multiple devices into a network PS2 connector makes possible direct connection between xl2000 and PC keyboard.
ISP downloading head,support to download program from host PC to board. Reset circuit. All pins are connected to IDC connectors for further expansion.
The Graphic LCD (GLCD) allows advanced visual messages to be displayed. The most commonly used graphic LCD has a screen resolution of 128x64 pixels. Digital thermometer DS1820 for measuring temperature from -50oC to 125oC.

  XL2000 is easy to use Atmel 8051 development system. XL2000 has many features that makes your development easy. You can between USB Power supply. Easy8051B also supports Graphic LCD.

The smart choice for 8051 microcontrollers
  XL2000 allows the 8051 MCU to be interfaced with external circuits to a broad range of the peripheral devices, allowing the user to concentrate just on the software.

Features of XL2000 system:
  Open modular design?? Each module is designed to connect to I/O port of Microcontroller. Connection of module with any port of Microcontroller is conveniently achieved through dupont thread. All I/O ports are open externally with output socket. Expansion is easily accomplished.

  XL2000 (dark PCB for double faces, the SMT art makes it maybe the most elegant MCU experiment system you have ever seen, luxurious and noble, you will love it at the first sight.

  A beginner?Worry not. Easy-to-learn BASIC syntax, advanced compiler features, built-in routines, and the many practical examples that we have provided allow a quick start in programming 8051.

More ISP downloading options:
  With complementary software, XLISP programmer represents a great tool for . The microcontroller connects to the XLISP programmer via 6 lines, two of which are +5V and GND and others are MOSI, MISO, SCK and MCLR. Unlike programmers whose operation is based on bootloads (and which need to give away part of their memory to a bootload program) XLISP programs the microcontroller externally so that the entire memory is available for the programmer.
