Overview

DW52 is a Wi-Fi/DECT baseband processor that can serve as either a cordless-handset or cordless-base baseband processor. Enabling the simultaneous activation of both Wi-Fi and DECT optional radio links, DMW52 handles audio voice processing through the integration of a DSP processor. The processor also features additional hardware acceleration modules to enhance power and performance.
