Product introduction:The FT32F030xx/FT32F032xx uses a high-performance ARM®Cortex®-M0 32-bit RISC core with a maximum operating frequency of 72 MHz, built-in high-speed memory (up to 64k bytes of flash memory and 8k bytes of SRAM) and rich enhance d I/O ports. The chip includes standard communication interfaces (2 I2C interfaces, 2 SPI interfaces, 2 USART interfaces), 1 12-bit ADC and 7 general-purpose 16-bit counters and 1 advanced control PWM counter. Three low power modes guarantee the requirements of low power applications. Support SWD interface debugging, 2 watchpoints and 4 hardware breakpoints for easy debugging.Application areas:Application controls and user interfaces, handheld devices, A/V receivers and digital television, PC peripherals, gaming and GPS platforms, industrial applications, programmable controllers, inverters, printers, scanners, alarm systems, video intercom and HVAC.CPU characteristics:·         Operating voltage: 2.0V ~ 5.5V·         Operating temperature range: -40℃~105℃·         RISC core based on ARM Cortex-M0 32-bitü  32-bit hardware multiplier with single instruction cycleü  NVIC with 32 interrupt vectors, 4 prioritiesü  Support for SWD interface debugging, 2 watchpoints and 4 hardware breakpoints·         Memory architectureü  Flash program memory: 64KBü  Data RAM: 8KB·         3 Low power modes: Sleep/Stop/StandbyPeripheral characteristics:·         Clock sourceü  Built-in 40KHz low frequency oscillatorü  Built-in 14MHz intermediate frequency oscillatorü  Built-in 48MHz high-frequency oscillator to support hardware calibrationü  Support 32KHz low frequency crystal, support hardware calibrationü  Support 4MHz-32MHz crystals and external clock inputü  Programmable PLL with frequency doubling up to 72MHz·         55 high speed IO'sü  Can be mapped to external interrupt vectorsü  PA8 ~ PA10, PA13 ~ PA15, PB0 ~ PB1, PB3 ~ PB7 support LED driversü  All I/O support 1/2VDD bias·         5 channel programmable DMA controller·         CRC module for programmable polynomials·         1 Msps 12-bit ADCü  16 external channelsü  Internal channels: temperature sensor, internal voltage reference, 2 operational amplifiers, and 2 sampled-hold circuitsü  internal reference voltages: 2.5V·         2 high speed comparators·         The 7-bit DAC is connected to the inverting terminal and configurable·         1 operational ampü  The op-amp output can be used as an ADC input·         Real-time clock and calendar RTC moduleü  Support intrusion detection, alarm clock and periodic wake up·         10 Timersü  TIM1, 16-bit, 4-channel PWM, supports 3 complementary pairsü  TIM3, 16-bit, 4-channel PWMü  TIM14, 16-bit, 1-channel PWMü  TIM15, 16-bit, 2-channel PWM, supports 1 complementary pairü  TIM16/TIM17, 16-bit, 1-channel PWM, supports 1 complementary pairü  TIM6, 16-bit, basic timerü  2 Watchdogs: WWDG and IWDGü  1 24-bit system timer·         Communication interfaceü  2 I2C, where I2C1 supports FM+ and SMBusü  2 SPI, supporting 4 to 16bit framesü  2 USART, support synchronous SPI mode as well as Modem control, automatic baud rate detection
