Support tools for efficient motor control

The new product line-up comprises a total of six new devices with pin counts from 80 to 100 pin and on-chip flash memory capacities from 128kB to 256kB. The RX24T Group enables simultaneous inverter control of multiple motors with a single chip and are well suited for permanent magnet AC (PMAC) motor control in a variety of applications.

The RX24T Group offers up to 160 DMIPs, including dedicated analogue functions to optimise the inverters’ Bill of Material (BoM) and furthermore increases the arithmetic operation and expands the motor control peripheral functions of the cost optimised RX23T.

In addition, Renesas plans to deliver a 24V motor control evaluation kit that can support both the single motor control RX23T and the multi-motor control RX24T.

Recently many countries have imposed legal requirements mandating improved motor efficiency, in addition to regulations intended to reduce energy consumption. This has increased demand for highly efficient inverter control.

However, this has also created numerous concerns for system manufacturers who want to quickly release products for this new market but who lack the necessary development workforce and motor control expertise. In addition, many types of equipment are becoming more compact, reducing the amount of space available for printed circuit boards. Finding ways to reduce the number of components in order to integrate multiple boards and reduce their number has therefore become a major issue.

In response to this demand for better energy efficiency, higher precision control, reduced board size and shorter development time, Renesas has developed the RX24T Group, a 32-bit Group of MCUs that enables control of multiple motors with a single chip.
