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, TQFP Product Overview The ATMEGA1284P-AU is a low power CMOS 8bit microcontroller based on AVR enhanced RISC architecture in 44 pin TQFP 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 ATMEGA1284P-AU has internal calibrated RC oscillator, on-chip analogue comparator, programmable watchdog timer with separate on-chip oscillator, two 8bit timer/counter with separate pre-scaler and compare mode, two 16bit timer/counter with separate pre-scaler, real time counter with separate oscillator and six PWM channels. Up to 20MIPS throughput at 20MHz 128KB of in-system self programmable flash program memory 4KB EEPROM and 16KB internal SRAM memory Qtouch library support JTAG (IEEE std 1149.1 compliant) interface 8 channel, 10bit A/D converter Operating voltage range from 1.8V to 5.5V 32 programmable I/O lines Two programmable serial USART, two wire serial and SPI interfaces Operating temperature range from -40°C to 85°C Product Information Product Range: AVR ATmega Family ATmega128 Series Microcontrollers CPU Speed: 20MHz Program Memory Size: 128KB Operating Frequency Max: 20MHz RAM Memory Size: 16KB No. of Pins: 44Pins MCU Case Style: TQFP IC Case / Package: TQFP No. of I/O's: 32I/O's Interfaces: I2C, SPI, USART Supply Voltage Min: 1.8V Supply Voltage Max: 5.5V MCU Family: AVR ATmega MCU Series: ATmega128 Operating Temperature Min: -40°C Operating Temperature Max: 85°C IC Mounting: Surface Mount Qualification: - MSL: MSL 3 - 168 hours
