USB comm. connector for MCU with USB facilities.RS-485 communication for connecting multiple devices into a networkPS2 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.

Outlook of 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.

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.

Equipped with 40pin simulator head and SST89E516 Emulation chip:

It could be used as an independent simulator for 51 MCU.  With the help of KEIL software, it supports on-line debugging like single step execution, break point and full run

The new SoftICE software utility was specifically developed to support the FlashFlex
SST's SoftICE is a downloadable micro-controller-resident software utility that provides in-circuit emulation capability through the Keil Monitor51 software, a popular third-party Windows monitor interface. It is the only software utility on the market today that provides "true" in-circuit emulation without the need for a "bondout" chip or on-board "hooks" circuitry. It helps debug users' target software in real-time, thus providing engineers with an in-circuit development tool, which is effective, easy to use and requires no extra emulator hardware. SoftICE has most of the features of sophisticated hardware emulators.
Some important features are:
Full access to every Flash memory location, RAM location, and SFR for READ/WRITE/ERASE operations.
Inline Assembler allows for on-the-fly change of test code. Any changes made using the inline assembler are implemented immediately on the hardware and in real-time.
SoftICE works invisibly with the user-friendly Keil Monitor51 driver to ensure the user the most comfortable code development environment.
