PT32C302 PCT普誠 微控制器芯片 

DESCRIPTION

The PT32C302 microcontrollers is a series of lowpower microcontrollers incorporating a highperformance ARM CortexTM-M0 32-bit RISC core.It operates at a maximum 48 MHz frequency andfeatures up to 64 Kbytes of Flash and up to 8 Kbytesof SRAM. A comprehensive set of power-savingmodes allows it to be employed in low-powerapplications. Extensive range of enhancedperipherals and I/Os are available allowing thedevice to be adopted in different application. Acomprehensive set of power-saving modes allows itto be employed in low-power applications. TheFlash program memory can be reprogrammed insystem through the SWD interface. 

PT32C302 USB MCUs subseries let you easy toimplement industry standard USB connectivity. Anon-board USB 2.0 full-speed function Host / Devicecontroller with an integrated transceiver and noexternal crystal or oscillator required for the USB.Elimination of external clock reduces the overallsystem cost associated with developing a USBdevice application, make it easy to add USBfunctionality to the embedded system. In order tosupport the crystal-less USB device operation, afactory-trimmed internal 4 MHz High Speed clocksource is capable of generating the 48MHz clock forUSB module and a USB clock recovery circuit isincluded on this microcontroller.

PT32C302 microcontroller peripheral set alsoincludes an External Bus Interface, 2x UARTs, 2xI2C, 2x I2Ss, 3x SPIs, 4x general-purpose 16-bittimers, 2x advanced 16-bit timers, an RTC, an ADC,a 12-bit DAC and four analog comparator.
