ATtiny85

  • ATtiny85 - 8-bit AVR Microcontrollers - Microcontrollers and Processors - Microcontrollers and Processors
    • The high-performance, low-power Microchip 8-bit AVR RISC-based microcontroller combines
      • 8KB ISP flash memory, 512B EEPROM, 512-Byte SRAM, 其中 Flash 放程式，SRAM 放執行期變數，EEPROM 則用來存資料。
      • 6 general purpose I/O lines, 總共 8 個腳位，扣除 VCC 與 GND，剩下的腳位都可以用。
      • 32 general purpose working registers,
      • one 8-bit timer/counter with compare modes, one 8-bit high speed timer/counter, 跟 PWM 有關?
      • USI, 是 Universal Serial Interface 的縮寫，用途??
      • internal and external Interrupts,
      • 4-channel 10-bit A/D converter,
      • programmable watchdog timer with internal oscillator,
      • three software selectable POWER SAVING MODEs,
      • and debugWIRE for on-chip debugging.
    • The device achieves a throughput of 20 MIPS at 20 MHz and operates between 2.7-5.5 volts. 其中 MIPS 是 Million Instructions Per Second 的意思，運算能力還是很強!
    • By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, BALANCING power consumption and processing speed. 速度夠快又省電，再加上 power saving modes 就更不得了了。
