描述 Description

The high-performance Microchip 8-bit AVR RISC-based microcontroller combines 4KB ISP flash memory, 256-Byte EEPROM, 256B SRAM, 16 general purpose I/O lines, 32 general purpose working registers, debugWIRE for on-chip debugging, an 8-bit timer/counter with compare modes, an 8-bit high speed timer/counter with PWM and separate prescaler, universal serial interface (USI), internal and external interrupts, an 11-channel 10-bit A/D converter, programmable watchdog timer with internal oscillator, and four software selectable power saving modes. The device operates between 2.7-5.5 volts.
By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processor speed.
