Configurable AFE, high-precision analog RL78/I1E microcontroller
The RL78/I1E microcontroller is an intelligent, flexible analog MCU suitable for countless industrial and medical sensing applications such as flow measurement, strain gauges, pressure or temperature sensing. With enhanced analog features such as configurable OpAmps with programmable gain, supporting inverting, non-inverting topologies, or instrumentation amplifers, the RL78/I1E can be a platform for different types of sensors. The RL78/I1E features a 24-bit delta-sigma A/D, and a separate 10-bit A/D block, with a 12-bit D/A. The package line up for RL78/I1E MCU goes down to 4 mm x 4 mm or 5 mm x 5 mm reducing PCB footprint. Operating temperature up to 125C makes it an ideal solution for the harshest of environments.

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).|
