STM32W108CBU64

Product Summary

The STM32W108CBU64 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 ZigBee-based systems.The STM32W108CBU64 offers a number of advanced power management features that enable long battery life. A high-frequency internal RC oscillator allows the processor core to begin code execution quickly upon waking. Various deep sleep modes are available with less than 1 μA power consumption while retaining RAM contents. To support user-defined applications of the STM32W108CBU64, on-chip peripherals include UART, SPI, TWI, ADC and general-purpose timers, as well as up to 24 GPIOs. Additionally, an integrated voltage regulator, power-on-reset circuit, and sleep timer are available.
