5 1/2 Digit LCD, Micro-Power Event/Hour Meter
Description
The ICM7249 Timer/Counter is intended for long-term battery-supported industrial applications. The ICM7249 typically draws 1µA 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. The ICM7249 is a 48 lead device, powered by a single DC voltage source and controlled by a 32.768kHz quartz crystal. No other external ponents are required. Inputs to the chip are TTL-patible and outputs drive standard direct drive LCD...
