Product Overview

The ATMEGA32U4-MU is a high performance, low power 8bit AVR RISC based microcontroller in 44 pin VQFN package. This device achieves throughputs approaching 1MIPS per MHz by executing powerful instructions in a single clock cycle. This allows system designer to optimize power consumption versus processing speed. The device has 32 general purpose working registers, four flexible timer/counters with compare modes and PWM, high speed timer/counter with compare modes and PLL adjustable source, 12 channels 10bit ADC with optional differential input stage, on-chip calibrated temperature sensor and programmable watchdog timer with internal oscillator.
  • Maximum operating frequency of 16MHz
  • 32KB of in-system self programmable flash
  • 2.5KB internal SRAM
  • JTAG (IEEE std 1149.1 compliant), USB 2.0, USART and SPI interfaces
  • Operating voltage range from 2.7V to 5.5V
  • 26 general purpose I/O lines
  • Power-on reset and programmable brown out detection
  • External and internal interrupt sources
  • Internal 8MHz calibrated oscillator
  • Operating temperature range from -40°C to 85°C
