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.
