Overview

The RL78/F1x sophisticated MCU family is the successor of the well known 78K0R/Fx3, R8C/3x and R8C/5x that realize low power consumption and high performance for a broad range of automotive applications such as cost-effective ECUs like switches, remote keyless entry, wiper, HVAC, lighting modules and engine sub controllers.

Roadmap

RL78/F1x RL78/F12 RL78/F13 RL78/F14

Application

RL78/F1x can be used at least for the following target application areas:

  • body control module (sub-MCU)
  • switch / indicator
  • adaptive front lighting system (AFS)
  • air conditioning
  • power window
  • tire pressure monitoring system (TPMS)
  • high-intensity discharge lighting system (HID)
  • remote control
  • wiper
  • powertrain (sub-MCU)
  • airbag (sub-MCU)
  • low-end car audio

Features

  • -40 to 150 ℃ operation

  • LIN/CAN interface

  • True low power
    Graph: Comparison of consumption current,CPU is activated only when required. Built-in energy-saving (SNOOZE) mode.

  • Combines the superlative technologies of the 78K and R8C, enabling effective use of software resources
    Drawing from both the 78K and the R8C to realize advanced specifications
