Memory and package lineups have been expanded from the RX610; USB, 12-bit A/D and other enhanced peripheral functions


With flash memory capacities from small to large and package pin counts from low to high, the RX630 Group can satisfy the demands of a variety of embedded devices. All the products of the RX630 Group are equipped with E2 data flash capable of 100,000 rewrites and enhanced peripheral functions with increased numbers of channels including timers, USB 2.0 function module, serial communication interface, I2C bus interface, CAN, 10-bit and 12-bit A/D converter, and 10-bit D/A converter. In particular, built-in features such as RTC with timestamp, temperature sensor, independent WDT, and POR/LVD enable the number of external parts to be reduced. We are also planning on releasing small packages such as LGA and BGA.

Software Design Support

Title Description
e² studio This integrated development environment (IDE) is based on the popular combination of the open-source Eclipse IDE and its CDT plug-in that enables C/C++ language development.
CS+ This integrated development environment (IDE) can be used for coding, assembly, compiling, and simulation. CS+ is also included with starter kits.
E2 emulator Lite This entry-level on-chip debugging emulator provides functionality equivalent to that of the E1 emulator at a low price.
E2 emulator This on-chip debugging emulator has advanced features that improve the efficiency of development. In addition to the basic functions from debugging to flash programming, this emulator supports hot plug-in and external triggers as standard items. This emulator also helps to reduce development time by downloading at high speeds (compared to the E1 emulator) and the ability to work in combination with various solutions such as the tuning of current drawn by systems under development.
E20 emulator This on-chip debugging emulator has enhanced debugging facilities such as large-capacity tracing and real-time RAM monitoring when used in combination with RX600 and RX700 MCUs (this emulator provides debugging functionality equivalent to that of the E1 emulator for other MCUs).
E1 emulator This on-chip debugging emulator is a standard model which provides basic debugging functions (production is to be discontinued at the end of December 2019).


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.
