Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced semiconductor solutions, today launched the RX13T Group of 32-bit microcontrollers (MCUs) to enable highly efficient inverter control of compact motors such as fans or pumps in consumer and industrial applications that previously controlled motor operation through on-off switching. This includes factory equipment where energy efficiency is a priority such as water discharge, supply pumps, or cooling fans for data sensor servers; and cordless, battery-powered household products where longer operating periods are demanded, such as electric power tools and vacuum cleaners.
- RXv1 CPU core with operating frequency of 32 MHz and performance of 98.56 CoreMark (Note 2)
- On-chip FPU eliminates need for overflow processing when performing fixed-point arithmetic operations and contributes to more readable software code
- Support for a wide range of power supply voltages from 2.7V to 5.5V. Offering 5V support provides a high level of noise tolerance
- Incorporates MTU3 timer module for inverter control. The timer counter clock operates on a high-speed clock frequency equal to the CPU’s operating frequency, making it easy to generate complementary PWM output with dead time that is required for inverter control
- Channel-dedicated sample and hold function (for three channels) enables simultaneous sampling of three phase current values, eliminating the need for error correction and lightening the software load
- 128 kilobytes (KB) or 64 KB of on-chip code flash memory and 12 KB of on-chip SRAM, There is also 4 KB of on-chip data flash memory, eliminating the need for external EEPROM.
- On-chip peripheral functions such as three-channel PGA, three-channel comparator, and high-speed on-chip oscillator (HOCO, accuracy of ±1.0%) reduce the need for peripheral components
- Models are available with support for an operating temperature range of -40°C to 85°C or -40°C to 105°C. This meets the increasing need in both the industrial and consumer fields for products capable of operating in high-temperature environments
