8-bit Low-Power PIC® and AVR® Microcontrollers

Our 8-bit eXtreme Low Power (XLP) 8-bit PIC microcontrollers (MCUs) and AVR MCUs with picoPower® technology are ideal for conserving power in battery-powered, connected applications like wearables, wireless sensor networks and other Internet of Things (IoT) devices.

Low-Power Sleep Modes with Flexible Wake-Up Sources

  • Sleep current down to 20 nA
  • Deep sleep current down to 9 nA
  • Low-power self-wake-up sources: special low-power Brown-out Reset (BOR), Power-on Reset (POR), Watchdog Timer (WDT), Real-Time Clock (RTC), INT, Asynchronous Master Clear Reset (MCLR)
  • Idle and Doze lower-power modes

Flexible and Advanced Integrated Peripherals

  • 20+ Core Independent Peripherals (CIPs) to offload the CPU while enabling sensor interfacing, waveform control, timing/measurements, logic/math, safety/monitoring, communications and user interface functionality
  • Intelligent analog features include 12-bit Analog-to-Digital Converter with Computation (ADCC), op amps, comparators, Digital-to-Analog Converters (DACs) 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 backup powered separately
  • Robustness in hostile environments
  • Low-power and robust touch sensing technologies

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
