Electronic Toy (Electronic Pet)


Electronic pets are a type of electronic toy that incorporates communication functions that enable it to move and react like a real pet dog or cat. The market for this type of product now spans a wide range of age groups and has grown to include healing therapy and nursing care applications. Prices continue to diversify, but demand is concentrated in the lower age groups. The product specifications of electronic pet toys combine capabilities such as DC motor control, simple audio output/input control, control of sensors of various types, and LED control. There is also a need for control functions for battery drive.

Renesas’ product lineup includes the 78K0 Series, the 78K0R Series and the R8C/3x Series, with multiple multifunction timers (8 bits with 8-bits prescaler,16 bits with input capture function and output compare function, 8bit with real-time clock mode and output compare mode) and support for low-voltage operation. These MCUs are suitable for a variety of electronic toys, supporting many types of input and output at low cost and providing plenty of configuration flexibility.
