Renesas’ the RL78/L1x Series of MCUs contain devices suitable for use as heating control and display operation. For example, the RX130 Group (48-100 pins) chips are ideal solutions for touch-key MCUs. Renesas also supplies devices such as control TRIACs. Our broad product portfolio enables our customers to design IH control systems with better performance, less power, and lower cost.

In addition, to address the trend toward stricter restrictions on harmonic components in the input current of electrical products, Renesas Electronics has a lineup of PFC power supply IC products (power-factor correction ICs) that are effective in suppressing electrical noise.
