Microchip 9ATMEGA32U4-MU) 8 Bit MCU, Low Power High Performance ,16 MHz

8 Bit MCU, Low Power High Performance, AVR ATmega Family ATmega32 Series Microcontrollers, 16 MHz 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 Applications Embedded Design & Development Product Information Product Range: AVR ATmega Family ATmega32 Series Microcontrollers CPU Speed: 16MHz Operating Frequency Max: 16MHz RAM Memory Size: 2.5KB No. of Pins: 44Pins MCU Case Style: VQFN IC Case / Package: VQFN No. of I/O's: 26I/O's Embedded Interface Type: SPI, USART Interfaces: SPI, USART Supply Voltage Min: 2.7V Supply Voltage Max: 5.5V MCU Family: AVR ATmega MCU Series: ATmega32 MSL: MSL 3 - 168 hours
