The APM32F030x6/x8 series chips are 32-bit high-performance microcontrollers based on the Arm Cortex-M0+ core, with an operating frequency of up to 48MHz. Built-in high-speed memory (up to 64KB of Flash and 8KB of SRAM), the chip pins multiplex a large number of enhanced peripherals and I/Os. All chips provide standard communication interfaces: I2C interface, SPI interface, and USART interface. The operating temperature range of the APM32F030x6/x8 microcontrollers is -40℃ to +105℃, and the voltage range is 2.0 to 3.6V, with multiple power-saving modes ensuring the requirements of low-power applications. The APM32F030x6/x8 microcontrollers include various different package forms from 32, 48, and 64 pins, and different package forms result in different peripheral configurations within the devices.
