Renesas Electronics has added two new functions to some members of its RX63T group of microcontrollers (MCU) which derives from the company’s successful RX600 series of high-speed, high-performance midrange MCUs.
The newly added functions, which are available on a total of 41 products with pin counts of 100 pins to 144 pins, are PWM (pulse-width modulation) delay generation and digital power management control.
The PWM delay generation function enables high-resolution adjustment of PWM output in increments as small as 312,5 picoseconds, allowing precise and optimised power control. The digital power management control function entails the integration of a digital power management controller in hardware. It provides a robust control algorithm that automatically compensates for inconsistency in the characteristics of the elements within the power supply unit.
The result is a solution that reduces the system design engineering burden related to manual tuning of a power supply. The new functions are both driven by high-speed hardware, which allows the use of higher switching frequencies and contributes to more compact power supply dimensions.
