General Description

The HT1350 is a step counter IC implemented in the CMOS technology. It provides an LCD with a whole course (kilometer/mile) as well as the consumed calorie display.

The HT1350 consists of internal oscillator circuit, a step number/kilometer/mile/calorie step counter, a voltage doubler, and an LCD display multiplexer.

The IC can automatically distinguish walking from jogging, thus making appropriate calculations.
