The Renesas R5F52318ADFP#30 is a high-performance, low-power 32-bit microcontroller from the RX231 Group, built around the Renesas RXv2 CPU core with enhanced DSP and single-precision floating-point processing capability.
Operating at up to 54MHz, the device integrates 512KB of program Flash memory, 64KB of RAM and 8KB of data Flash, providing sufficient processing and memory resources for embedded control, human-machine interface and communication applications.
The R5F52318ADFP#30 operates from a wide 1.8V to 5.5V supply voltage range and provides up to 80 I/O ports, allowing flexible connection to sensors, actuators, displays and external peripherals.
Integrated communication functions include USB Full-Speed host/peripheral support, CAN, UART, SPI and synchronous serial interfaces, making the MCU suitable for embedded systems requiring multiple wired communication options.
For mixed-signal applications, the device integrates a 12-bit ADC with up to 24 channels, 12-bit DAC with 2 channels, temperature sensing and multiple timer resources. It also includes a 24-channel capacitive sensing unit, enabling touch-key and human-machine interface designs without requiring a separate touch controller.
The R5F52318ADFP#30 is supplied in a 100-pin LFQFP package measuring 14 × 14 × 1.7 mm with 0.5 mm pin pitch. Its operating temperature range is -40°C to +85°C, making it suitable for a wide variety of embedded, consumer and equipment-control applications.
