Enhanced CAN / LIN / IEBus and memory lineup from RL78/F14
RL78/F15 automotive microcontrollers employ the RL78 core, which realizes high processing performance while delivering the lowest power consumption in its class.
A high-speed on-chip oscillator provides 32 MHz CPU operation. An enhanced motor control functionality is offered by the motor control timer (Timer RD), the D/A converter and a built-in comparator. For easy migration RL78/F15 is pin- and software upwards compatible to RL78/F14.
The RL78/F15 Group even supports 125 ℃ (target) operation, whereby a CPU clock of 24 MHz can be reached. In addition abundant functions to support functional safety, like ECC on RAM and a stack pointer monitor as well as a A/D converter testing function are available.
With packages from 48 to 144-pin, a memory range from 128 to 512 KB flash, and advanced IPs for LIN and 2 channels of CAN communication and IEBus, these products are very well suited for a broad range of cost sensitive automotive applications like DC- & BLDC motor control, HVAC, lighting and many kinds of body ECUs.

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).|
