The STM32W108 is a fully integrated System-on-Chip that integrates a 2.4 GHz, IEEE 802.15.4-compliant transceiver, 32-bit ARM® Cortex™-M3 microprocessor, Flash and RAM memory, and peripherals of use to designers of 802.15.4-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.
The integrated 32-bit ARM® Cortex™-M3 microprocessor is highly optimized for high performance, low power consumption, and efficient memory utilization. Including an integrated MPU, it supports two different modes of operation: Privileged mode and Unprivileged mode. This architecture could be used to separate the networking stack from the application code and prevent unwanted modification of restricted areas of memory and registers resulting in increased stability and reliability of deployed solutions.
The STM32W108 has 128/192/256 Kbytes of embedded Flash memory and 8/12/16 Kbytes of integrated RAM for data and program storage. The STM32W108 HAL software employs an effective wear-leveling algorithm that optimizes the lifetime of the embedded Flash.
