Keil Announces New Development Tools for 8051 MCUs

C51 Version 8 Compiler
and µVision 3 Development Environment
speed 8051 MCU development

Plano, TX: Keil today announced availability of its new µVision3 development environment and C51 Version 8 optimizing compiler for classic and extended 8051 microcontroller (MCU) development. Together, these products provide developers with a feature rich, integrated development environment optimized for a wide range of 8051 MCU variants.

The new µVision3 development environment integrates the latest C51 Version 8 compiler and features source code outlining, function navigator, template editing and incremental search. It also incorporates a configuration wizard, which speeds the generation of start-up code and configuration files. The built-in microcontroller simulator can model supported MCU devices, including the instruction set, on-chip peripherals and external signals used to stimulate it. Application behavior can be visualized using the µVision3 logic analyzer, showing the changing state of MCU pins and peripherals alongside program variables. This latest edition of µVision3 ships with support for several new 8051 MCU variants released in the past nine months including the Analog Devices ADuC83x and ADuC84x, and the Infineon XC866.

"This latest release of our development tools demonstrates our continued commitment to the 8- and 16-bit MCU marketplace and brings our 8051 tools inline with the rich feature set our customers enjoy when designing with C166 as well as ARM Powered^® MCUs," said Reinhard Keil, director of Microcontroller Tools, Keil. "The new µVision3 development environment and C51 Version 8 optimizing compiler will enable faster and easier development of 8051 solutions."
