Overview
Induction Heat cooking is gaining popularity due to its low power cooking requirements and safety advantages. IH cooking models capable of accommodating all types of metal cooking implements are now available and are marketed as suitable for the "all electric" home. These must be able to distinguish between the material of the pots or pans placed on them, and require high-performance MCUs to control the heating process. In addition, touch displays are now rapidly becoming the standard for control panels as they provide ease of use and more importantly to the housewife, ease of cleaning.
Renesas has a varied lineup of products suitable for use as the control MCUs, display-operation MCUs, and touch-key MCUs within an IH cooker application. These include the H8S/Tiny Group, the M16C/65 Group, the R8C/3x Series, the R8C/Lx Series, the R8C/3xT Group, SH7149 Group and the V850E/Ix3. These MCUs provide IH control with improved performance, reduced power consumption, and lower cost.
