New development tools support low-power V850E2 microcontrollers from Renesas Electronics

March 19, 2012 // By Paul Buckley
IAR Systems is offering complete support for the V850E2/Fx4-L microcontroller series from Renesas Electronics which features low power consumption paired with high functionality. The device is designed for the automotive comfort and body segment, for applications such as roof or window lifters, HVAC (heating, ventilation, and air conditioning), body control modules, and door, seat and light modules.

The new microcontrollers provide power-saving features such as the sequencer (SEQ). The SEQ supports hardware monitoring of digital inputs in deep stop mode without any usage of the CPU or memory. When the SEQ detects activities at the digital inputs, the device switches from deep stop mode to run mode. Another feature is the LIN-master controller (LMA) which supports the automatic LIN-frame detection without CPU interactivity.

The highly-optimizing C/C++ compiler and debugger tool suite IAR Embedded Workbench for V850 supplies extensive support for all devices in the V850, V850E, V850ES, and V850E2 families. The V850E2/Fx4-L microcontrollers are supported by IAR Embedded Workbench for V850 version 3.81, available today. This new release also adds support for Reneas E20 emulator, integration with the version control system Subversion, and new license features, such as commuter licenses, automatic license activation and support for virtual servers.

IAR Embedded Workbench is available for a variety of Renesas targets, in total more than 4.000 devices. IAR Systems is the largest independent vendor of development tools for Renesas microcontrollers, and is committed to continue to deliver high-performing, user-friendly tools for all Renesas microcontrollers.
