ATMEL ATMEGA8A-AU 微控制器, 8位, 低功率高性能, ATmega, 16 MHz, 8 KB, 1 KB, 32 引脚, TQFP
The ATMEGA8A-AU is a 8-bit high-performance low-power AVR RISC-based Microcontroller combines 8kB ISP flash memory with read-while-write capabilities, 512B EEPROM, 1kB SRAM, 23 general purpose I/O lines, 32 general purpose working registers, three flexible timer/counters with compare modes, internal and_external interrupts, serial programmable USART, a byte oriented Two-Wire serial interface, 6-channel 10-bit A/D converter, programmable watchdog timer with internal oscillator, SPI serial port and_five software selectable power saving modes. The device operates between 2.7 to 5.5V. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and_processing speed.
.Advanced RISC architecture - On-chip 2-cycle multiplier.High endurance, non-volatile memory segments.QTouch® library support - Capacitive touch buttons, sliders and_wheels.Peripheral features - Byte-oriented Two-Wire serial interface.Power-on reset (POR) and_programmable brown-out detection.Internal calibrated RC oscillator.External and_internal interrupt sources.Five sleep modes - Idle, ADC noise reduction, power-save, power-down and_standby
