Overview The Keil development tools for the 8051 Microcontroller Architecture support every level of software developer from the professional applications engineer to the student just learning about embedded software development. The Keil 8051 Development Tools are designed to solve the complex problems facing embedded software developers. The industry-standard Keil C Compilers, Macro Assemblers, Debuggers, Real-time Kernels, Single-board Computers, and Emulators support all 8051 derivatives and help you get your projects completed on schedule. The Keil µVision IDE fully integrates Cx51 and provides control of the Compiler, Assembler, Real-Time OS, Project Manager, and Debugger in a single, intelligent environment. With support for all 8051 devices and full compatibility with emulators and third-party tools, Keil Cx51 is clearly the best choice for your 8051 project. Keil C51 is the industry-standard toolchain for all 8051-compatible devices, it supports classic 8051, Dallas 390, NXP MX, extended 8051 variants, and C251 devices. The µVision IDE/Debugger integrates complete device simulation, interfaces to many target debug adapters, and provides various monitor debug solutions. The Keil µVision Debugger accurately simulates on-chip peripherals (I²C, CAN, UART, SPI, Interrupts, I/O Ports, A/D Converter, D/A Converter, and PWM Modules) of your 8051 device. Simulation helps you understand hardware configurations and avoids time wasted on setup problems. Additionally, with simulation, you can write and test applications before target hardware is available. Keil µVision IDE The Keil µVision IDE combines project management, make facilities, source code editing, program debugging, and complete simulation in one powerful environment. The µVision development platform is easy-to-use and helping you quickly create embedded programs that work. The µVision editor and debugger are integrated in a single application that provides a seamless embedded project development environment. Multiple drivers are included for debugging applications running on target hardware:
µVision Linker & Locator The LX51 linker/locator combines object modules and creates executable 8051 programs. The linker resolves external and public references and assigns absolute or fixed addresses to relocatable program segments. The LX51 linker processes object files created by the Keil C51 Compiler, CX51 Compiler, A51 Assembler, AX51 Assembler, and the Intel PL/M-51 Compiler and ASM-51 Assembler and generates an absolute OMF2 object module. µVision Debugger The µVision Debugger provides source-level debugging and includes traditional features like simple and complex breakpoints, watch windows, and execution control as well as sophisticated features like performance analyzer, code coverage, and logic analyzer. The µVision Debugger may be configured as a Simulator where programs run on your PC; or as Target Debugger where programs run on your target hardware. The cycle-accurate µVision Simulator is a software-only product that simulates most features of your 8051/251 device without actually having target hardware. µVision Simulator The µVision Simulator allows you to debug programs using only your PC and device simulation drivers provided by Keil and various third-party developers. A good simulation environment, like µVision, does much more than simply simulate the instruction set of a microcontroller — it simulates your entire target system including interrupts, startup code, on-chip peripherals, external signals, and I/O. Benefits of µVision Device Simulation are:
Target Hardware The µVision Debugger allows you to debug programs running on target systems using target drivers provided by Keil and various third-party developers. Licensing Options & System Req.

Language ToolsThe Keil Cx51 ANSI C Complier supports all classic and extended 8051 device variants. Compiler extensions provide full access to all CPU resources and support up to 16MB memory. The Keil Cx51 generates code with the efficiency and speed of hand-optimized assembly. New compiler and linker optimizations shrink programs into the smallest single-chip devices. The Cx51 Compiler allows you to write 8051 microcontroller applications in C that, once compiled, have the efficiency and speed of assembly language. Language extensions in the C51 Compiler give you full access to all resources of the 8051. The C51 Compiler translates C source files into relocatable object modules which contain full symbolic information for debugging with the µVision Debugger or an in-circuit emulator. In addition to the object file, the compiler generates a listing file which may optionally include symbol table and cross reference information. Features
Debuggers and ProgrammersKeil ULINK2Keil ULINK2 The Keil ULINK2 Debug Adapter connects your PC's USB port to your target system (via JTAG, SWD, or OCDS) and allows you to program and debug embedded programs on target hardware. Using the ULINK2 adapter together with the Keil µVision IDE/Debugger, you can easily create, download, and test embedded applications on target hardware.  Features
Keil SmartMX DBox The Keil SmartMX DBox enables software debugging and integration testing for NXP (founded by Philips) SmartMX  smart card controllers. It is based on the NXP SmartMX bondout device and integrates seamlessly with the µVision IDE to provide a high-performance development and debugging platform.
