Honeywell has developed a 3-axis compass IC in a chip-scale package designed to improve accuracy and location readings in consumer electronics applications such as mobile phones, personal navigation systems and portable automotive navigation systems.

The HMC5843 chip stimulates functionality in consumer electronics by providing expanded direction awareness when overlaid on GPS-enabled maps, easing to read digital maps on handheld devices. The IC includes three-axis magnetoresistive sensors, a 12bit ADC, and an I2C serial bus interface in a 4mm x 4mm x 1.3mm surface-mount package, which uses Honeywell's patented manufacturing IP for the Z-axis sensor.
