Our microcontrollers (MCUs) with an integrated LCD controller offer the following benefits for segmented displays:

  • Support direct LCD panel drive capability; no external components needed
  • Lower system cost
  • Generate different voltage levels through integrated voltage bias generation
  • Support a range of fixed and variable bias options and variable clock inputs

Key Features of MCUs with an Integrated LCD Controller


Software Contrast Control

  • Use firmware to boost or dim the contrast of the display
  • Boost the contrast up to VDD or beyond using MCUs with an integrated charge pump
  • Vary the contrast on the LCD to account for different operating conditions such as temperature, lighting and humidity
  • Invaluable for portable applications especially when the battery level drops

picoPower® Technology

  • Ultra-low-power MCUs (490 nA backup with Real-Time Clock (RTC), 39 uA/MHz active)
  • Faster wake-up times and on-the fly user-selectable performance levels
  • Event System, SleepWalking peripherals and multiple power domains
  • LCD with Direct Memory Access (DMA) and SleepWalking support

eXtreme Low Power Technology

  • Lowest power (sleep currents down to 20 nA, active mode currents down to 50 µA/MHz) for longest battery life
  • Sleep mode flexibility: RAM retention, fast wake-up and flexible wake-up sources
  • Brown-out rest down to 45 nA provides protection as batteries are depleted
  • Watchdog Timer down to 200 nA  provides protection against system failure
  • RTC down to 400 nA  provides precise timekeeping
  • Drive glass in sleep mode, for reduced power consumption and longer battery life

Peripheral Touch Controller

  • Supports low-power, high-sensitivity, robust touch buttons, sliders and wheels
  • Supports up to 256 mutual-capacitance channels and up to 32 self-capacitance channels
  • Low power consumption: 4 uA standby with multi-button wake-up on touch

Charge Time Measurement Unit (CTMU)

  • Provides constant current source with a range from 0.550 µA to 550 µA
  • Used in applications like capacitive touch, time domain reflectometry, humidity measurement, precise time measurement, temperature measurement and more

Real-Time Clock and Calendar (RTCC)

  • Available in many PIC® MCUs for timekeeping and calendar applications 
  • Can be calibrated and provides hours, minutes, and seconds using the 24-hour format 
  • Highly configurable alarm and can wake up external devices without CPU intervention 
  • Can run in deep sleep mode and is optimized for long-term battery operation 
  • Reduces cost and speeds up development, especially in applications which require display of time or day

Featured Product: PIC24F ‘GU/GL/GP” MCUs with Core-Independent Autonomous Animation


Animations like alternating between displays, blinking and blanking of pixels are common in most LCDs. The PIC24F ‘GU/GL/GP’ family of MCUs features an integrated LCD driver with autonomous animation to offload most of these animation routines from the CPU. This allows you to enable animation in power-saving modes while the CPU is in doze, idle or sleep mode.
