ARM KeilCx51 Development Tools and PK51 Professional Developer’s Kit
This full suite of Cx51 development tools generates code with the efficiency of hand-optimised assembly code. Supports all classic & extended 8051 architecture.
- Support for all 8051 microcontroller variants
- Easy-to-use IDE which supports your whole development cycle
- RTX Tiny2 multi-tasking real-time kernel
- LX51 extended linker lets you increase the program space of an 8051 device beyond 64 KB
- μVision Debugger for source-level debugging

Product Description
The Keil PK51 Professional Developer’s Kit includes the complete set of Cx51 development tools which support the 8051 architecture:
Cx51 CompilerDepending on the device variant, there are three types of compiler provided in the Cx51 range. For classic 8051 devices including 8051 IP cores and Dallas Contiguous Mode, the C51 compiler produces optimised code. For Philips 8051 MX and SmartMX devices, the CX51 compiler is included. For 251 devices and IP cores, you can use the C251 compiler. These variants allow you to take full advantage of all hardware peripheral components and optimise memory use.
LX51 Extended LinkerIncrease the program space of a classic 8051 device past the 64 KB limit. Expands device support and adds extra features and functionality to the Cx51 compiler including linker code packing, incremental linkage, far memory support and data type checking.
RTX Tiny2 Real-Time KernelRoyalty free multitasking real-time kernel providing single chip and code banking support, round robin and cooperative task switching, task management and interrupt support. Also supports multiple DPTR and arithmetic units.
μVision DebuggerIncludes all the “standard” features such as simple and complex breakpoints, watch windows and execution control as well as advanced features like performance analyser, code coverage and logic analyser. It can be made to run as a simulator on your PC or on target hardware. μVision Simulator can simulate peripherals including IO, CAN, I2C, SPI, EEPROM and UART.
Support ALL 8051 Variants
Cx51 ANSI C Compiler supports all classic and extended 8051 device variants. Compiler extensions provide full access to all CPU resources & support up to 16MB memory.
East-to-use IDE
μVision4 IDE fully integrates Cx51 Version 9 and provides control of the Compiler, Assembler, Real-Time OS, Project Manager, and Debugger in a single, intelligent environment.
Tiny but Real
The RTX Tiny2 multi-tasking real-time kernel makes implementing complex, time-critical software projects easy. This royalty-free kernel is fully integrated into the Keil Cx51 tool chain.
