8-bit eXtreme Low-Power (XLP) PIC® and picoPower AVR® Microcontrollers

Microchip’s large portfolio of low power 8-bit PIC and AVR microcontrollers is ideal for: 

Low Power Sleep modes with flexible wake up sources

  • Sleep current down to 20nA
  • Deep sleep current down to 9nA
  • Low power self-wake-up sources: Special Low Power BOR, POR, WDT, RTC, INT, MCLR
  • Idle and Doze lower power modes

Flexible and Advanced Integrated peripherals

  • 20+ Core Independent Peripherals (CIPs) to offload CPU while enabling sensor interfacing, waveform control, timing/measurements, logic/math, safety/monitoring, communications and user interface functionality
  • Intelligent analog features include 12-bit ADC with Computation, Op Amps, Comparators, DAC and more.
 

Long battery life with robust and reliable features

  • Enable battery lifetime of 20+ years
  • Low-power supervisors for safer operation (BOR, WDT)
  • Core Independent Peripherals (CIPs) perform tasks at lowest possible energy requirement
  • VBAT battery back-up powered separately
  • Robustness in hostile environments
  • Robust touch sensing technologies with low power

Large portfolio and efficient performance across voltage range

  • 6–100 pins
  • Up to 384 KB Flash
  • Up to 16 KB RAM
  • 1.6V to 5.5V operation
  • Wide selection of package options
  • Peripherals run autonomously in low power modes
