Microcontrollers for Bidet Toilets

Microcontrollers are used for many functions of bidet toilets, such as controlling a heated control seat, a deodorizing fan motor and a remote control, and driving water heater and a nozzle. With increased interested in Ecology, the latest energy-saving development is a toilet seat that quickly warms up after a sensor is activated as you approach.

The Basic Concept of The Product

5V Microcontrollers for General Applications
Diversifying features of a bidet toilet have been requesting more function and higher-performance of a microcontroller. For example, data from sensors need to be processed with high speed in order to control with high accuracy the amount of water, deodorizing and a water heater. For a bidet toilet, Toshiba have microcontrollers(M380 Group(Note)) with 5V incorporating multiple AD converters that are capable of high-speed conversion and multiple timers for controlling the temperature of a heater without increasing the CPU load.

Note: Arm® Cortex®-M3 Microcontrollers : TX03 Series
