The General-purpose microcontroller with lower operating current than RL78/G13

The RL78/G13A microcontrollers have the same functions as RL78/G13, with much lower operating current (47μA/MHz: over 40% reduction from RL78/G13*). They also support 105℃ operating ambient temperature which is not supported by RL78/G13 (Program Flash: 384/512KB products). They can be used in a wide variety of applications, from home and consumer appliances to industrial equipment.

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).
