Description
The RX671 group microcontrollers deliver superior real-time performance with the RXv3 core running at 120MHz. The HMI functions enable contactless operation by proximity switches and voice recognition, making it possible to realize hygienic HMI suitable for the new normal. A wide variety of packages, including the 4.5mm x 4.5mm 64-pin TFBGA, is all equipped with 2MB flash memory and 384KB SRAM to meet a wide range of needs with a single chip.
