Microchip (ATMEGA1284P-AU) 8 Bit MCU, 20 MHz, 128 KB, 44 Pins, TQFP

8 Bit MCU, AVR ATmega Family ATmega128 Series Microcontrollers, 20 MHz, 128 KB,44 Pins, TQFPProduct OverviewThe ATMEGA1284P-AU is a low power CMOS 8bit microcontroller based on AVRenhanced RISC architecture in 44 pin TQFP package. This device achievesthroughputs approaching 1MIPS per MHz by executing powerful instructions in asingle clock cycle. This allows system designer to optimize power consumptionversus processing speed. The ATMEGA1284P-AU has internal calibrated RCoscillator, on-chip analogue comparator, programmable watchdog timer withseparate on-chip oscillator, two 8bit timer/counter with separate pre-scaler andcompare mode, two 16bit timer/counter with separate pre-scaler, real timecounter with separate oscillator and six PWM channels.Up to 20MIPS throughput at 20MHz128KB of in-system self programmable flash program memory4KB EEPROM and 16KB internal SRAM memoryQtouch library supportJTAG (IEEE std 1149.1 compliant) interface8 channel, 10bit A/D converterOperating voltage range from 1.8V to 5.5V32 programmable I/O linesTwo programmable serial USART, two wire serial and SPI interfacesOperating temperature range from -40°C to 85°CProduct InformationProduct Range: AVR ATmega Family ATmega128 Series MicrocontrollersCPU Speed: 20MHzProgram Memory Size: 128KBOperating Frequency Max: 20MHzRAM Memory Size: 16KBNo. of Pins: 44PinsMCU Case Style: TQFPIC Case / Package: TQFPNo. of I/O's: 32I/O'sInterfaces: I2C, SPI, USARTSupply Voltage Min: 1.8VSupply Voltage Max: 5.5VMCU Family: AVR ATmegaMCU Series: ATmega128Operating Temperature Min: -40°COperating Temperature Max: 85°CIC Mounting: Surface MountQualification: -MSL: MSL 3 - 168 hours
