ST STM32W108C8无线MCU 2.4GHz开发方案

ST 公司的STM32W108C8是集成了64KB闪存的高性能IEEE 802.15.4无线系统级芯片(SoC),包括有2.4 GHz IEEE 802.15.4兼容的收发器,32位ARM Cortex-M3微处理器,闪存和RAM,以及基于ZigBee的系统外设. 正常情况下的接收灵敏度为-99dBm,输出功率为+3dBm,能WiFi与蓝牙共存,单电源2.1-3.6 V工作,主要用在ZigBee RF4CE遥控和人工接口设备,2.4 Ghz IEEE 802.15.4 MAC网络,消费类电子设备和简单的网络RF控制.本文介绍了STM32W108C8主要特性,方框图,以及STM32W-SK评估板和STM32W-EXT 扩展板电路图和相应的材料清单.

The STM32W108C8 is a fully integrated System-on-Chip that includes a 2.4 GHz IEEE 802.15.4-compliant transceiver, a 32-bit ARM?Cortex?M3 microprocessor, Flash memory and RAM, and peripherals of use to designers of ZigBee-based systems.

The transceiver utilizes an efficient architecture that exceeds the dynamic range requirements imposed by the IEEE 802.15.4-2003 standard by over 15 dB. The integrated receive channel filtering allows for robust co-existence with other communication standards in the 2.4 GHz spectrum, such as IEEE 802.11 and Bluetooth. The integrated regulator, VCO, loop filter, and power amplifier keep the external component count low. An optional high performance radio mode (boost mode) is software-selectable to boost dynamic range.
