Renesas RX14T Motor Control Microcontrollers (MCUs)

Simplified motor control with integrated analog and timing functions

Renesas RX14T is an entry-level motor control microcontroller designed to deliver an optimal balance of performance, integration, and cost for home appliances and industrial equipment. Powered by a 48MHz RXv2 core with single-precision floating-point support, the RX14T integrates essential motor control peripherals including PWM timers, dual 12-bit ADCs, programmable gain amplifiers, comparators, and a high-speed on-chip oscillator to simplify system design and reduce component count.

Designed for reliable operation in electrically noisy environments, the RX14T supports 5V operation and offers compatibility with the RX13T and RX23T MCU families, enabling easy software and hardware migration while accelerating product development.
