The Propeller is easily connected to your computer’s serial or USB port for programming using our Prop Plug. The Propeller chip can run on its own with a 3.3-volt power supply, internal clock, and with its internal RAM for code storage. Add an external EEPROM for non-volatile code storage and an external clock source for accurate timing.\u003c\/p\u003e\n\u003ch5\u003e\u003cspan class=\"forte\"\u003eFeatures:\u003c\/span\u003e\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eMulticore processing simplifies designs subject to asynchronous requirements\u003c\/li\u003e\n\u003cli\u003eQFP package for small footprint circuits\u003c\/li\u003e\n\u003cli\u003eBuilt-in Spin language is easy to learn\u003c\/li\u003e\n\u003cli\u003ePropGCC support provides a familiar feel for C\/C++ programmers\u003c\/li\u003e\n\u003cli\u003ePropeller Assembly language supports deterministic timing using single-path, multi-decision techniques\u003c\/li\u003e\n\u003cli\u003eInternal or external clock sources provide flexible speed options\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003e\u003cspan class=\"rotforte\"\u003eNote:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e 160 Tested Chips in a Tray. \u003c\/p\u003e\n\u003ch5 class=\"ui-accordion-header ui-helper-reset ui-state-active ui-corner-top\" role=\"tab\"\u003e\n\u003cspan class=\"forte\"\u003eP8X32A-Q44\u003cspan\u003e \u003c\/span\u003e\u003c\/span\u003eDetails:\u003c\/h5\u003e\n\u003cdiv id=\"details\" class=\"tabbed details ui-accordion-content ui-helper-reset ui-widget-content ui-corner-bottom ui-accordion-content-active\" role=\"tabpanel\"\u003e\n\u003cdiv class=\"field-tech\"\u003e\n\u003cul\u003e\n\u003cli\u003ePower requirements: 2.7 to 3.3 VDC\u003c\/li\u003e\n\u003cli\u003eCommunication: Serial for programming\u003c\/li\u003e\n\u003cli\u003eDimensions: 0.39 x 0.39 x 0.05 in (10 x 10 x 1.4 mm)\u003c\/li\u003e\n\u003cli\u003eOperating temp range: -67 to +257 °F (-55 to +125 °C)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003e\u003cspan class=\"forte\"\u003eP8X32A-Q44 Pin Assignments:\u003c\/span\u003e\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eP0-P31: General purpose I\/O.  Can source\/sink 40 mA each at 3.3 VDC\u003c\/li\u003e\n\u003cli\u003eP31: Rx from host (general purpose I\/O after boot up)\u003c\/li\u003e\n\u003cli\u003eP30: Tx to host (general purpose I\/O after boot up\/download)\u003c\/li\u003e\n\u003cli\u003eP29: I2C SDA connection to external EEPROM (general purpose I\/O after boot up)\u003c\/li\u003e\n\u003cli\u003eP28: I2C SCL connection to external EEPROM (general purpose I\/O after boot up)\u003c\/li\u003e\n\u003cli\u003eVdd: Power (3.3 VDC)\u003c\/li\u003e\n\u003cli\u003eVss: Ground (0 VDC)\u003c\/li\u003e\n\u003cli\u003eBOEn: Brown Out Enable (active low).
