An 8-bit general-purpose microcontroller equipped with large current output terminals for LED drive
Even though the RL78/G1N microcontroller has a small pin-count 20-pin package, it is an 8-bit general-purpose microcontroller equipped with large current output terminals for driving LEDs. It allows direct drive of 8-segment 6-digit high brightness LEDs. It is suitable for small appliances, simple lighting fixtures and LED displays for portable batteries, etc.

|Power supply voltage||VDD = 2.0V Note) ~5.5V|
|Operating temperature||TA = -40 °C ~ +85 °C (A: Consumer applications, D: Industrial applications)|
Note) Use with a voltage range of 2.25V to 5.5V because it includes detection voltage (VSPOR) for the selectable power-on-reset (SPOR) circuit.
Pin Count/Memory Size Lineup:
* Use this product within the voltage range from 2.25 to 5.5 V because the detection voltage (VSPOR) of the selectable power-on-reset (SPOR) circuit should also be considered.

Software Design Support
|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).|
