STM32W108C8 is an IEEE802.15.4-based wireless communication chip with ultra-strong RF performance, low power consumption, and high integration.
The STM32W108C8 is a fully integrated System-on-Chip designed for ZigBee-based systems and remote control applications. It combines a 2.4 GHz IEEE 802.15.4-compliant transceiver with a 32-bit ARM Cortex-M3 microprocessor, 64 Kbytes of Flash memory, and 8 Kbytes of RAM. The device features exceptional radio performance with a normal mode link budget up to 102 dB and robust WiFi and Bluetooth coexistence.
The chip offers advanced power management capabilities, including a low deep sleep current of 400/800 nA and a high-frequency internal RC oscillator for fast processor start-up. It includes various peripherals such as UART, SPI, I2C, ADC, and up to 24 GPIOs. The device is available in a small 7x7 mm 48-pin VFQFPN package.
