RX24U
The RX24U Group features a 32-bit microcontroller ideally suited for dual inverter control with a built-in Floating-Point Unit (FPU) that enables it to easily execute complex inverter control algorithms. The built-in Differential Programmable Gain Amplifier and the provide safety system allow to bring application system cost down.
Products with the operating ambient temperature of 105 °C are also available.
The easy usability of the RX24U is helping our customers to reduce the time to market by reducing software development efforts and system design by providing a ready-to-go motor control solution, including software and hardware design examples.

|---|---|
| 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). |
