1. General Description
EWB160031M module features a fully integrated 2.4GHz radio transceiver and baseband
processor for Wi-Fi 802.11b and Bluetooth® Smart applications. It can be used as a standalone
application-specific communication processor or as a wireless data link in hosted MCU systems
where ultra-low power is critical. It supports flexible memory architecture for storing profiles,
stacks and custom application codes, and can be updated using Over-The-Air (OTA) technology.
Qualified Bluetooth Smart protocol stack and Wi-Fi TCP/IP stack are stored in a dedicated
ROM.
EWB160031M module uses OPULINKS OPL1600 SoC. It is equipped with dual processors,
ARM® Cortex®-M0 and M3, for handling different processes. All software runs on the ARM®
Cortex®-M0 processor while more intensive application-specific activities run on the ARM®
Cortex®-M3 processor. EWB160031M can be connected to any external MCU through SPI, I2C
or UART interfaces and sensors or other devices through GPIOs. The transceiver interfaces
directly to the antenna and is fully compliant with the Wi-Fi 802.11b and Bluetooth 5.0 BLE
standards. With integrated antenna switch, RF balun, power amplifier (PA) and low noise
amplifier (LNA), the OPL1600 allows both Wi-Fi and Bluetooth Smart to minimize PCB design
area and external component requirement. The block diagram for OPL1600 is shown as below.
