ARM ® Cortex™-M0 Microcontroller

DESCRIPTION

The PT32C302 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 up to 64 Kbytes of Flash and up to 8 Kbytes of SRAM. A compreh ensive 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. PT32C302 USB MCUs subseries let you easy to implement industry standard USB connectivity. An on-board USB 2.0 full-speed function Host / Device controller with an integrated transceiver and no external crystal or oscillator required for the USB. Elimination of external clock reduces the overall system cost associated with developing a USB device application, make it easy to add US B functionality to the embedded system. In order to support the crystal -less USB device operation, a factory-trimmed internal 4 MHz High Speed clock source is capable of generating the 48MHz clock for USB module and a USB clock recovery circuit is included on this microcontroller. PT32C302 microcontroller peripheral set also includes an External Bus Interface, 2x UARTs, 2x I2C, 2x I2Ss, 3x SPIs, 4x general -purpose 16 -bit timers, 2x advanced 16-bit timers, an RTC, an ADC, a 12-bit DAC and four analog comparator.
