Overview

Description

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 32MHz CPU operation. An enhanced motor control functionality is offered by the motor control timer (Timer RD). For easy migration, RL78/F15 is pin and software upwards compatible with RL78/F14. The RL78/F15 Group even supports 125 ℃ (target) operation, whereby a CPU clock of 24 MHz can be reached. In addition, an abundance of functions to support functional safety, like ECC on RAM and a stack pointer monitor as well as an A/D converter testing function are available. With packages from 48 to 144-pin, a memory range from 128KB to 512KB 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 and BLDC motor control, HVAC, lighting and many kinds of body applications.
