SANTA CLARA, USA: Renesas Electronics announced the availability of 32 new RL78/F12 16-bit microcontrollers (MCUs) that contribute to reduced system power consumption and higher performance for automotive control systems, including keyless entry, power window control, mirror control, and other applications.
The new MCUs are the first group of devices in Renesas’ F Series of automotive products in the new RL78 Family that feature industry-leading low power consumption and high performance. The RL78 Family combines the superlative technologies of Renesas' main existing products in the 8-/16-bit MCU market, the 78K (78K0 and 78K0R) and R8C, and integrates an extensive set of peripheral functions around the RL78 CPU core, which is based on the low-power/high-performance 78K0R CPU core.
As a result of the growing number and functionality of MCUs in automobiles, there is an increasing demand for MCUs that can provide even lower power consumption, a reduction in printed circuit board mounting areas, and provide technology to reduce overall system-component count.
To respond to these needs, Renesas has released the F Series of automotive MCUs in the RL78 Family that inherit the excellent features of the earlier Renesas R8C and 78K (78K0 and 78K0R) low-power MCUs that have a proven track record in automotive applications. Aiming at extreme reductions in power consumption, these new products respond to the need for 8-/16-bit devices that can reduce total costs across whole system structures.
Furthermore, the trend toward mechatronics, in which electronic control and mechanical components are integrated together, is progressing, and performance when operating at high temperatures, such as in the engine compartment or headlights, is now desired. At the same time, efforts at responding to functional safety standards are becoming increasingly important. Therefore Renesas has included a rich set of diagnostic functions in the RL78/F12 MCUs to support high-temperature operation and functional safety.
