Crypto Benchmark on RX65N MCU
RXv2 @ 120 MHz

This benchmark conducted on Renesas Starter Kit+ for RX65N-2MB (RX65N-2MB-Starter-Kit-Plus) will help you in qualifying performance of CycloneCRYPTO (Cryptography library), CycloneSSL (TLS 1.3 & DTLS 1.2 library), CycloneSSH (SSH library with SCP & SFTP protocols), CycloneIPSEC (IPsec/IKEv2 library) and CycloneTCP (TCP/IPv4/IPv6 stack with secure protocols like HTTPS, FTPS, MQTTS, Secure WebSocket, Secure CoAP, Secure Modbus/TCP, SNMPv3...) running on Renesas RX65N microcontroller.

RX65N MCU also includes crypto hardware acceleration. In the following comparison charts, both hardware and software performance are presented in the relevant sections.
