Product Description:

The FT32F072xx uses a high-performance ARM Cortex-M0 32-bit RISC core operating at up to 72MHz, with built-in high-speed memory (up to 64k bytes of Flash and 8k bytes of SRAM) and a rich set of enhanced I/O ports. The chip includes standard communication interfaces (2 I2C interfaces, 2 SPI interfaces, 2 USART interfaces and 1 USB interface), a 12-bit ADC and 7 general-purpose 16-bit counters and an 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. It supports SWD interface debugging, 2 observation points and 4 hardware breakpoints, which is convenient for users to debug.

Application Areas:

Application control and user interface, handheld devices, A/V receivers and digital TVs, PC peripherals, gaming and GPS platforms, industrial applications, programmable controllers, inverters, printers, scanners, alarm systems, video intercom and HVAC.
