Broadcom Corporation - BCM2044S - ROM-Based Noise And Echo Reduction Mono Headset IC

The Broadcom BCM2044S is a monolithic 0.13 m, single-chip Bluetooth 2.0 + EDR mono headset solution with very low power consumption. This is the first headset IC in the world that implements SmartAudio noise and echo reduction algorithms in integrated ROM, without the need of external Flash on BOM; hence significantly reducing the BOM. This ROM solution has been designed to permit the lowest possible BOM for high- and mid-range mono headsets. The ROM contains a default application built on top of the highly interoperable Broadcom BTE-Audio Stack. Sophisticated configurability has been built into the default application allowing customers to differentiate. A small patch RAM space is also provided for last minute code changes prior to production.
