Based on the fast RX core, the new 32-bit MCUs are ideal for building high-performance inverter control systems for applications such as DC motor control in energy-efficient electric home appliances such as refrigerators, air conditioners, washing machines, vacuum cleaners, and fans; entry-level to mid-range industrial equipment such as general-purpose inverters, electrical tools, and drones; and office equipment. The functions are optimized for single inverter drive, including the inclusion of an on-chip floating point unit (FPU) that reduces code size and development time both by 30 percent.

Energy efficiency regulations have become stricter in many countries in recent years, expanding to include entry-level and mid-range energy-efficient electric home appliances and industrial equipment. System designers in these price-competitive markets are looking for new approaches to achieve the reduced power consumption desired within increasingly constrained budget requirements for energy-efficient, cost-attractive products. The demand for more compact, more highly efficient, and quieter motors in office equipment such as printers and multifunction units has led to a move away from stepping motors and toward the adoption of brushless DC motors. There is a need for more highly precise position control without increased system cost.

To respond to these market demands for improved energy efficiency, more precise control, and lower development cost, Renesas has developed the RX23T Group of MCUs, offering an excellent cost-to-performance ratio. The new MCUs provide an optimized subset of the functions of the RX62T Group, which has a proven track record in the inverter control field, designed specifically for use in single inverter drive applications.

Features:

－ Highly precise inverter control and reduced development time for mid-range and entry-level devices

－ High power efficiency among the best in the industry for even lower power consumption in inverter products

－ Support for 5 V peripheral I/O, making it easier to implement measures to reduce effects of electromagnetic noise from inverter drive
