the high-performance, low-power atmel 8-bit avr risc-based microcontroller combines 128kb isp flash memory with read-while-write capabilities, 4kb eeprom, 8kb sram, 48 general purpose i/o lines, 32 general purpose working registers, real time counter, four flexible timer/counters with compare modes and pwm, usart, byte oriented 2-wire serial interface, usb 2.0 low-speed and full-speed on-the-go (otg) host/device, an 8-channel 10-bit a/d converter with optional differential input stage with programmable gain, programmable watchdog timer with internal oscillator, spi serial port, jtag (ieee 1149.1 compliant) interface for on-chip debugging, and six software selectable power saving modes.
by executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 mips per mhz, balancing power consumption and processor speed.
