Specially designed for lamp ballast and motor control applications,the 8-bit AVR microcontroller is based on the Atmel AVR enhanced RISC architecture. The device features 8Kbytes of ISP read-while-write flash, 512-byte EEPROM, 512-byte SRAM, 7-channel advanced PWM, 8-channel 8-bit ADC, a 10-bit DAC,four software selectable power saving mode, two or three 12-bit high speed po.wer stage controllers with 4-bit resolution enhancement, and DALI protocol support. Operating voltage is 2.7V - 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.
