General-purpose microcontrollers with built-in high-resolution A/D converter, suitable for measurement devices and sensor applications
RL78/G1A microcontrollers balance the industry's lowest level of consumption current (CPU: 66 μA/MHz, standby (STOP): 230 nA) and a high performance of 43.2 DMIPS (32 MHz). A built-in high-resolution 12-bit A/D converter, on-chip oscillator, data flash, and safety features (function that detects illegal operation of hardware) enable support for the household appliance safety standard (IEC/UL 60730). With an lineup of 25 to 64-pin LGA/BGA and other small packages, these microcontrollers are perfect for consumer and industrial sensor applications.

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).|
