Product introduction:The FT32F032xx uses a high-performance ARM®Cortex®-M0 32-bit RISC c 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 enhanced 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. In addition, the chip has a built-in touch sensor, providing 24 capacitive sensing channels, which can be applied to products requiring touch control. Three low power modes ensure 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·         Storage architectureü  Flash program memory: 64KBü  Data RAM: 8KB·         Three 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, supports 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·         7 bit DAC are attached to the inverting end, 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  Two watchdogs: WWDG and IWDGü  1 24-bit system timer·         Communication interfaceü  2 I2C, where I2C1  supports FM+ and SMBusü  2 SPI  that support bit frames from 4 to 16bitü  2 USART, support synchronous SPI mode as well as Modem control, automatic baud rate detection·         Touch Sensing controllerü  24 touch keys
