Industry’s Lowest Power SubGHz wireless communication MCU

 

The RL78/G1H microcontroller supports IEEE802.15.4e/g and has industry’s lowest power consumption - min. 5.8 mA (3.3 V) at Stand-by mode in RF receipt. The balun circuit and filter circuit make the antenna circuit design easy. And it can be reduced external parts for cost reduction. It can be reduced CPU load and can be made easy development by built-in hardware functions for IEEE802.15.4e/g compliant especially Wi-SUN.

We also offer transceiver RAA604S00 conforming to IEEE802.15.4e/g that can be used in combination with microcontroller.  (The document is here.)

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.
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).
