RXv2 core at 48 MHz — timing budget for real-time control
The Renesas R5F51405AGFK#10 is a 32-bit single-core MCU from the RX140 series, built around the RXv2 CPU core running at 48 MHz.
Memory sizing — OTA staging and data logging headroom
Analog integration — 15-channel 12-bit ADC and 2-channel 8-bit DAC
The on-chip 15-channel 12-bit ADC and 2-channel 8-bit DAC reduce the need for external analog front-end components in sensor conditioning and closed-loop control applications. The ADC resolution is adequate for most industrial sensor interfaces; the DAC can generate analog setpoints or bias voltages.
The MCU includes CANbus, I²C, SCI, and SPI interfaces, making it suitable for industrial network nodes and multi-sensor aggregators. The capacitive touch peripheral supports touch-button or slider interfaces without an external touch controller. The 53 general-purpose I/O pins provide ample headroom for parallel displays, keypads, and actuator control.
Package and footprint — 64-LQFP (14x14 mm)
The surface-mount package is compatible with reflow soldering and typical PCB assembly processes.
The part is RoHS3 compliant. For BOM planning, this MCU is a safe choice for production programs that will run for several years.
