RX610

Description

RX610 Group microcontrollers have 100 MHz high-speed operation and large-capacity on-chip memory. The products are equipped with basic functions such as timers and communications functions, as well as four independent units of A/D converter, enabling a fastest conversion time of 0.8 μs. In addition to a maximum 2 MB flash memory and 128 KB RAM, 32 KB of flash memory for data storage are built in. The RX610 enables a system to be configured without peripheral memory and other devices, greatly reducing the total cost of the system.
