Renesas adds third-party SW & RTOS support for RL78 microcontroller family

May 09, 2011 // By Christoph Hammerschmidt
The software ecosystem for the RL78 microcontroller family, widely used in power-sensitive automotive and industrial applications is growing: RL78 manufacturer Rensas has announced that a new compiler from IAR Systems for the RL78 is available, as well as real-time operating systems (RTOS) from Micrium and CMX Systems.

According to Renesas, IAR Systems' Embedded Workbench provides a highly optimized C and C++ compiler for the RL78 MCU family and supports the E1 on-chip debugger and IECube in-circuit emulator tools, both from Renesas Electronics. Additionally, the Embedded Workbench comes bundled with the C-SPY real-time debugger and the instruction simulator.

Embedded designers can gain a competitive edge by using Micrium's feature rich, efficient, and scalable µC/OS-II and µC/OS-III kernels, which have been ported to the RL78 family of processors, explained Micrium CEO Jean Labrosse. According to the manager, battery-operated, power-sensitive and eco-friendly applications can also benefit from Micrium's µC/OS-II's and µC/OS-III's ability to easily enter the RL78 MCUs’ SNOOZE and HALT modes when idling.

In addition to the aforementioned software vendors, also RTOS supplier CMX Systems has ported its CMX-RTX operating system to the RL78 MCU family. CMX-RTX is a pre-emptive, multi-tasking RTOS offering one of the smallest footprints, fastest context switching times, and lowest interrupt latency times available, CMX said.
