Hearing Aids  Favorite


A hearing aid is a small electronic device worn in or behind the ear which amplifies incoming sounds for the hearing impaired.

Freescale's MCU and power management solutions help enable your hearing aid designs.

We have DSCs that offer the ease of use of a MCU and the mathematical precision of a DSP, allowing you to create cost-effective, low-power solutions.

In addition, Freescale offers an extensive power management portfolio, including variety of Lithium-ion battery chargers.
