ICM7249 - 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.

Features

  • Hour Meter Requires Only 4 Parts Total.
  • Micropower Operation: < 1µA at 2.8V (Typ).
  • 10 Year Operation On One Lithium Cell. 21/2 Year Battery Life with Display Connected.
  • Directly Drives 51/2 Digit LCD.
  • 14 Programmable Modes of Operation.
  • Times Hrs. , 0.1 Hrs. , 0.01 Hrs. , 0.1 Mins.
  • Counts 1’s, 10’s, 100’s, 1000’s.
  • Dual Function Input Circuit - Selectable Debounce for Counter - High-Pass Filter for Timer.
  • Direct AC Li.

ICM7249 August 1997 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 components are required. Inputs to the chip are TTL-compatible and outputs drive standard direct drive LCD segments. Features • Hour Meter Requires Only 4 Parts Total • Micropower Operation: < 1µA at 2.
