8位通用MCU系列产品包括PIC内核的LGT8F684N,AVR内核的LGT8F328P&LGT8F08A,均为Flash工艺。其中,684N主要特性为PWM可倍频到40M的输出,内置闭环差分运放,有4路80mA的PWM扇出/入能力, 定位于中低端8位MCU市场;328P可在绝大部分应用场景中替代ATMEGA328P,特别在创客或者教育机器人市场中以Arduino开发平台为主的应用场景中,有较完美的软硬件替代方案,并且相对于ATMEGA328P ,最多可使用通用I/O可到28,在其他工控&测控领域有较为广泛的应用;08A作为我司早期的产品,较为突出的特性具有UART口,在应用层面可作为USB1.1来使用,我司提供软件底层支持,可支持自烧录功能,PWM亦可倍频到40M以上来使用,在某些特殊应用场合中具有较高的性价比。
