ATMEGA328P-MUR

8位 MCU微控制单元, 低功率高性能, AVR ATmega Family ATmega328 Series Microcontrollers, 20 MHz, 32 KB, 2 KB

The is a 8-bit high-performance picoPower AVR RISC-based Microcontroller Unit combines 32kB ISP flash memory with read-while-write capabilities, 1024B EEPROM, 2kB 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 2-wire serial interface, SPI serial port, a 6-channel 10-bit A/D converter 8-channels in TQFP and QFN/MLF packages, programmable watchdog timer with internal oscillator and five software selectable power saving modes. All the 32 registers are directly connected to the Arithmetic Logic Unit ALU, allowing two independent registers to be accessed in one single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers.
