RX 32-Bit Microcontrollers Connectivity

The RX 32-bit microcontrollers (MCU) offer rich connectivity functions including Ethernet, USB and CAN that can support special applications such as industrial networks.

Additionally, they are equipped with advanced security functions such as Trusted Secure IP, which realizes a high level of security for the Internet of Things (IoT), and enable communication that meets requirements while protecting security and confidentiality.
