Introduction
EMC3380 is a high-performance module mainly used in voice applications of the Internet of Things. It
has a dual-core microcontroller with ultra-high integration, supports 2.4/5GHz dual-band Wi-Fi and BLE
5.0 wireless communication technology, and includes large capacity Flash, RAM, audio codec and audio
digital coprocessor to meet various complex requirements in speech application.
The core of high performance is a 32-bit core with a main frequency up to 200 MHz. Based on the latest
ARM v8-M architecture, it not only has low power consumption, but also can complete floating-point
operation and DSP instruction processing, thus completing the matching of audio coding and decoding
algorithm and deep learning model efficiently. The core frequency of high energy efficiency reaches
20MHz, which provides a simplified instruction system for ultra-low power applications, so that the
system can keep standby for a long time.
2.4/5GHz dual-band Wi-Fi guarantees stable Internet connection at any time. BLE 5.0 technology can not
only facilitate users to complete the rapid configuration of products, but also realize the intelligent
networking of a large number of local devices through Mesh technology.
The large capacity of Flash and RAM space allows developers to implement complex Internet of Things
cloud service communication protocols, achieve long-term cache of high-resolution audio resources, and
provide users with a perfect audio streaming media listening experience. The integrated dual
microphone interface and audio front-end processing DSP chip can collect excellent voice resource
samples for intelligent voice system, significantly reduce the algorithm complexity and improve the
recognition rate of AI system. Rich peripheral interfaces can maximize system customization and
expansion and facilitate the construction of innovative application products.
Shanghai MXCHIP provides MXOS software platform to support the development of EMC3380, providing
an efficient development environment, rich sample programs and typical applications.
