R5F5671EHDFB#30

RX671 microcontroller combines high performance, low power consumption, hygienic UI, cloud connectivity and extremely small package breaks the barrier of various limitations in small IoT applications. Compared to the RX651, the RX671 has enhanced features such as the higher power efficiency of 48.8 CoreMark/mA, capacitive touch sensing, voice recognition over long distances by digital microphones and easy-to-mount small 48-pin HWQFN package. Furthermore, the RX671 provides a more powerful choice to customers that need microcontrollers with a capacitive touch sensing unit. In the case of home appliances, the RX671’s cloud connectivity enables remote control from the outdoors, informing usage data to users, firmware update for correcting bugs or adding new functions. Additionally, the Trusted Secure IP protects communication data including user’s private information from eavesdropping and prevents firmware tampering by integrity check.
