L Series

8-bit microcontrollers


L Series is NEC Electronics’ new range of 8-bit microcontrollers combining low current consumption, high performance, and an integrated LCD controller to deliver cost effective solutions for applications requiring segment displays

  Key Benefits
  • Integrated LCD controller
    • simplifies circuit design
    • reduces system cost
  • Integral charge pump & waveform generator reduces external components
  • • 16-bit ΔΣ A/D available on 64 & 80-pin ‘Lx3’ devices
  • Powerful enough to drive & store complex applications & user menus
    • 20MHz maximum CPU clock speed
    • Lx3: 10MHz max for improved current consumption
    • large Flash & RAM sizes (up to 128K flash / 7K RAM)
  • All Flash based offering added flexibility
  • Fast wake up time using internal oscillator

Variety & Versatility

  • Multiple package / memory / LCD drive options
    • 48, 52, 64, 80 & 100-pin devices available
    • 8Kb to 128Kb single-voltage flash
    • 512b to 7Kb on-chip RAM
    • up to 288 segment LCD drive capability
  • Options include versions with & without A/D converter
    • trade cost against functionality
  • LCD drive & I/O capability vary with pin count

Manufactured on NEC’s advanced 0.15µm process

  • Greater performance for a given power consumption
  • Ideal for handheld or battery powered devices
    • very low current consumption
    • wide operating voltage range (1.8V – 5.5V)
    • high performance at low voltage (5MHz @ 1.8V)

Based on the popular K Series family

  • Core & peripheral commonality
    • easily migrate designs from K Series to L Series
    • allows software to be readily re-used to save development time
  • Highly scalable
    • upgrade to more memory or cost reduce with the same core features

High quality hardware & software tools

  • Fully supported by IAR Embedded Workbench
  • Supported by the latest low-cost ‘MiniCube2’ and IECUBE tool chain
    • low cost on-chip debug supported on all package sizes
    • full function emulator also available if required
  • Very low cost evaluation kit for immediate development (L Series SEE-IT!)
