The RX610 Group is built around the RX core and has enhanced analog, communication, and timer functions.


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.

Hardware Design Support

Title Description
IBIS/BSDL IBIS standard simulation data is required for high-speed board design and can be used to run simulations to examine and troubleshoot issues such as waveform reflection, ringing, and so on, before producing the actual board.
BSDL is a data input format supported by most IEEE 1149.1 (JTAG)-compliant tools. The automatic test pattern generation (ATPG) and automatic test equipment functions of these tools facilitate testing.
