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

  • Various Motor control(Brushless DC Motor Control Solution)
    pump, fan, power window, wiper, mirror, seat, adaptive front lighting system (AFS) etc.
  • Various body control
    door, switch / indicator, relay box, clearance sonar, air conditioning, tire pressure monitoring system (TPMS), lighting system (LED, HID) etc.
  • Low-end car audio
  • Powertrain (sub-MCU)
  • Airbag (sub-MCU)

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
