AT90PWM1 帶有8K系統內可編程Flash存儲器

Specially designed for Lamp ballast and Motor Control applications, the AT90PWM1 AVR microcontroller features 8 KBytes Flash memory, 7-channel advanced PWM, 8-channel 8-bit ADC, two 12-bit High Speed PSC (Power Stage Controllers) with 4-bit Resolution Enhancement.

The AT90PWM1 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the AT90PWM1 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
