Renesas Electronics Corp. has expanded its microcontroller family that works with power sensitive applications like tools and motor control.
The RL78 family includes 8 and 16 bit devices that feature application specific flexible application accelerator (FAA) and a CPU with an operating frequency of 48 MHz. The devices can distribute tasks such as inverter control, encryption, sensing and arithmetic operations that are efficient and independent of the CPU.
“Traditionally, processing was done only by the CPU core and a significant burden was placed on the CPU. Tuning to achieve a balance between high-speed processing and CPU load took a considerable amount of time,” said Osamu Ogura, software development manager, industrial system development division of Tessera Technology Inc., a Renesas eco-system partner. “With the FAA capability that comes with the RL78/G24, we were able to divide the communication processing for the CPU and power control as with the FAA. This allowed us to shorten the development time overall.”
Other features of the RL78 series are:
- 12 bit ADC
- High speed comparator
- Equipped DALI-2
- Temperature support up to 125° C
- Use in virtual models in Simulink
