Overview

The R8C/Lx Series has built-in LCD drive control circuit. It inherits many peripheral functions, such as a multifunction timer and a wealth of communication functions, from the R8C/3x Series, and the easy-to-use LCD drive control circuit from the 38000/740 and H8/300L Super Low Power Series. Possessing the following key features, the R8C/Lx Series aptly supports a variety of LCD panel devices*. In addition, the R8C/LAPS Group microcontrollers equipped with large-capacity flash memory (maximum 128 KB) are ultra-low power and low pin count.

  • Package lineup of 30, 32, 52, 64, 80, and 100 pins
  • 8, 16, 32, 48, 64, 96, or 128 KB on-chip Flash (differs by Group)
  • 5 MHz operation at 1.8 V supply voltage, and 20 MHz operation from 2.7 V available
  • Built-in great for power-saving applications*
  • Choice timers inherited from R8C/3x, 38000/740, and H8
  • On-chip and take the place of external reset IC
  • Built-in takes the place of external oscillator*
  • Built-in pin-level LCD port/general port switching function cuts down on invalid pins*

Industry top-class functions are built-in (R8C/L3xC Group and R8C/L3xM Group)

  • Industry top-class ROM/RAM: Max. 128 KB ROM, max. 10 KB RAM
  • High-function LCD drive control circuit
    • LCD drive control circuit supports up to 8COM and is capable of multi-pixel LCD panel display
    • On-chip LCD power supply voltage multiplier makes external power supply unnecessary
    • Built-in display control function in pixel units - automatic on/off display - → Further reduce power consumption during wait mode
  • great for data transfer
  • makes it possible to continue operating the CPU during data flash write/erase
  • Complementary PWM timer great for driving motors, etc.

Achieves industry top-class ultralow power consumption (R8C/LAxx Group)

  • Less than half the operating power consumption and standby power consumption compared to previous Renesas products
  • Built-in functions conducive to lowering system power consumption
    • Flash memory erasing/writing/reading at 1.8 V
    • Industry's first LCD with memory effect*
    • Full calendar RTC with automatic correction function*

* Not available in the R8C/LAPS Group.

Key Applications

Electronic household appliances, office equipment, audio equipment, consumer products, remote control, etc.
