应用功能： 5 1/2数字液晶显示，微功率事件/小时计 The ICM7249 Timer/Counter is intended for long-term battery-supported industrial applications. The ICM7249 typically draws 1mA during active timing or counting, due to Intersil’ special low-power design techniques. This allows more than 10 years of continuous operation without battery replacement. The chip offers four timing modes, eight counting modes and four test modes.
