RX13T are 32-bit microcontrollers optimized for single motor control applications and can help reduce board area and BOM costs.

The RX13T Group of microcontrollers are equipped with the proven RX Family RXv1 core operating at 32MHz, a floating point unit (FPU), an inverter control timer and a 12-bit A/D converter, allowing high-efficiency inverter control of brushless DC motors with one device. They are highly compatible with existing RX devices so it is easy to convert hardware and software from previous designs. The lineup includes small 32-pin and 48-pin packages with built-in features such as programmable gain amplifier (PGA), comparator, data flash, and high-speed on-chip oscillator (HOCO). These on-chip features can help reduce board area and the BOM components in the design.

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).
