ARM ® Cortex™-M0 Microcontroller
DESCRIPTION
The PT32 microcontrollers is a series of low -power microcontrollers incorporating a high -performance ARM CortexTM-M0 32-bit RISC core. It operates at a maximum 48 MHz frequency and features 32 Kbytes of Flash and 4 Kbytes of SRAM. A comprehensive set of power -saving modes allows it to be employed in low-power applications. Extensive range of enhanced peripherals and I/Os are available allowing the device to be adopted in different application. A comprehensive set of power -saving modes allows it to be employed in low -power applications. The Flash program memory can be reprogrammed in-system through the SWD interface. The PT32U301 MCUs give you any essential functionality as a General-purpose MCU. With its highly customizable peripherals, it eases the process of making your own ideal product. PT32U301 microcontroller peripheral set also includes an External Bus Interface, 2x UARTs, 1X I2C, 1 SPI, 3x general-purpose 16/32-bit timers, an RTC, 3x PWM, an ADC and four analog comparators.
