Overview

Renesas is introducing the RL78/D1x as an optimized solution for the BRICs and low-end instrument cluster markets.
The RL78/D1x is the successor of 78K0/Dx2 or UPD78082x microcontrollers and suited for car instrument cluster, built-in car instrument cluster dedicated features such as Sound Generator, Stepper Motor Controller/Driver and LCD Segment Controller/Driver etc.

Applications

Low-end Instrument Cluster

Roadmap

RL78/D1A

Features

Sound Generator

Sound Generator Image
  • Programmable tone frequency (100Hz to 6 KHz)
  • Programmable volume level
  • Automatic logarithmic volume decrement function

Stepper Motor Controller/Driver

  • 8-bit precision pulse width can be specified
  • Pseudo 9-bit precision pulse width can be specified by using the 1-bit addition function
  • PWM output is possible at frequencies up to 20 kHz
  • Automatic PWM phase shift for reducing fluctuation on power supply and for reducing the susceptibility to electromagnetic interference
  • Zero Point Detection (ZPD) function

LCD Controller/Driver

  • 4 com. x 27 to 53 seg.
  • Internal Resistance Division Method for LCD driver voltage generator
  • Automatic output of segment and common signals based on automatic display data memory read
  • Display mode : Static, 1/3 duty, 1/4 duty
  • Six different frame frequencies, selectable in each display mode
