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

8 Bit MCU, Low Power High Performance, AVR ATmega Family ATmega32 SeriesMicrocontrollers, 16 MHzProduct OverviewThe ATMEGA32U4-MU is a high performance, low power 8bit AVR RISC basedmicrocontroller in 44 pin VQFN package. This device achieves throughputsapproaching 1MIPS per MHz by executing powerful instructions in a single clockcycle. This allows system designer to optimize power consumption versusprocessing speed. The device has 32 general purpose working registers, fourflexible timer/counters with compare modes and PWM, high speed timer/counterwith compare modes and PLL adjustable source, 12 channels 10bit ADC withoptional differential input stage, on-chip calibrated temperature sensor andprogrammable watchdog timer with internal oscillator.Maximum operating frequency of 16MHz32KB of in-system self programmable flash2.5KB internal SRAMJTAG (IEEE std 1149.1 compliant), USB 2.0, USART and SPI interfacesOperating voltage range from 2.7V to 5.5V26 general purpose I/O linesPower-on reset and programmable brown out detectionExternal and internal interrupt sourcesInternal 8MHz calibrated oscillatorOperating temperature range from -40°C to 85°CApplicationsEmbedded Design & DevelopmentProduct InformationProduct Range: AVR ATmega Family ATmega32 Series MicrocontrollersCPU Speed: 16MHzOperating Frequency Max: 16MHzRAM Memory Size: 2.5KBNo. of Pins: 44PinsMCU Case Style: VQFNIC Case / Package: VQFNNo. of I/O's: 26I/O'sEmbedded Interface Type: SPI, USARTInterfaces: SPI, USARTSupply Voltage Min: 2.7VSupply Voltage Max: 5.5VMCU Family: AVR ATmegaMCU Series: ATmega32MSL: MSL 3 - 168 hours
