Microcontrollers

We are driving new advances in microcontrollers used in gas, water and heat meters to extend battery life, improve measurement accuracy and reduce system cost. Specialized peripherals lower the cost for ultrasonic flow measurement while new advances in nanoWatt eXtreme Low Power (XLP) technology pushes the industry into lower and lower power consumption levels. We offer a broad portfolio of low-power and highly integrated PIC® microcontrollers (MCUs) along with a common MPLAB® development ecosystem for easy migration across MCU families.

Microcontroller Technology Highlights

eXtreme Low Power (XLP) Technology

  • Sleep currents down to 20 nA and Real-Time Clock (RTC) down to 400 nA to extend operation in outage conditions
  • Wake-up sources including RTC, Watchdog Timer (WDT), Brown-out Reset (BOR), interrupts, eset and Power-on Reset (POR)

Efficient Processing Architecture to Lower Active Current

  • Reduces power consumption with shorter run times
  • Over 88% of PIC24 instructions are single cycle
  • As low as 150 uA/MHz run power on the 16-bit PIC24 MCU family
  • DMA transfers across peripherals to reduce power

Integrated Precision Time Measurement

  • Constant current source to calculate both capacitance and time changes
  • Charge Time Measurement Unit (CTMU) time measurement capabilities down to 500 pSec resolution
  • Precision temperature measurements using inexpensive diodes, Resistive Temperature Device (RTD), PTC and NTC sensors

Integrated Real-Time-Clock/Calendar (RTCC)

  • Full calendar and time with leap year adjustment
  • Built-in RTCCAL register for watch crystal calibration

LCD Integration

  • Up to 480 segments
  • Display in sleep mode
  • Integrated charge pump available for contrast control
