MCU Embedded Wi-Fi a/b/g/n + Bluetooth 5.0 + 802.15.4 Module with Integrated Antenna
WC640
Overview
WC640 series is Wi2Wi’s first MCU Embedded, Multi-Protocol (Tri-mode), highly integrated plug and play module with Dual Antenna on-board. With embedded microcontroller(s), WC640 module series is a complete wireless sub-system with multiple wireless technologies: Dual Band (2.4/5GHz) Wi-Fi, Bluetooth 5.0 (BLE), 802.15.4 (Zigbee) making it a perfect candidate for a vast variety of applications, including Internet-of-Things (IoT), Industrial IoT (IIoT), M2M, etc. This is low power host-less Internet of Things (IoT) wireless module offering multiple radios, wireless standards, protocols and connectivity framework support. WC640 multi radio embedded wireless module supports advanced seamless coexistence across multiple wireless technologies. Multi-core processing for optimized performance with a dedicated ARM Cortex-M4F processor for customer applications reducing development cost & efforts, which accelerates their time-to-market and low power ARM Cortex-M0 CPU dedicatedly used for BLE/802.15.4 protocol and Xtensa-based Wi-Fi CPU to offload Wi-Fi stack. WC640 host-less module is a subsystem that includes two antennas, baseband, LNA, PA, crystals, filter, RF front-end and flash for storing Firmware/s, calibration data, MAC addresses. WC640 self-contained wireless sub-system supports interfaces SPI, UART, I2C, PWM, I2S, ADC and GPIOs for external peripherals.
