The YF109 microcontroller utilizes a high-performance 32-bit ARM® Cortex®-M0+ core,offering a wide voltage operating range. With up to 32Kbytes of flash memory and 4Kbytes ofSRAM, it achieves a maximum operating frequency of 32MHz. The chip integrates variouscommunication peripherals, including I2C, SPI, and USART, as well as a 12-bit ADC, five16-bit timers, and two comparators.
In addition, the YF109 microcontroller features an embedded 2.4GHz wireless transceivermodule. Operating within the 2.400GHz to 2.483GHz ISM frequency band, it can reach amaximum transmit power of 8dBm. In open environments, its transmission range can reach120+ meters, while its receiver receiver adopts a low intermediate frequency structure with asensitivity of up to -86dBm. This module achieves high integration and requires a minimum ofonly two capacitors and a crystal oscillator as external components.
Operating across a temperature range of -40℃ to 85℃ and a voltage range of 1.7V to 5.5V(2.4GHz operation from 2V to 3.6V), the YF109 microcontroller provides low-power modes,including sleep and stop, catering to diverse low-power applications.
The YF109 microcontroller is suitable for various applications, including controllers, wirelesshandheld devices, smart homes, IoT systems, remote-controlled toys, wireless industrial controldevices and etc.
