Connectivity for PIC24 MCU and dsPIC® DSC Families 16-bit Embedded Control Solutions 9 Connectivity The PIC24 MCUs and dsPIC33 DSC products include a wide range of integrated connectivity peripherals as well as support for many wired and wireless communication protocols. Many of these communication libraries, such as USB and Wi-Fi, are integrated into the Microchip Libraries for Applications (MLA) which can be downloaded at www.microchip.com/MLA. CAN, LIN and SENT Many of the dsPIC® DSCs and PIC24 MCUs include an integrated CAN peripheral which is ideal for applications requiring robust communications with a high-speed, reliable industry standard protocol. Vector CANbedded™ and osCAN™ development solutions support PIC24 MCU and dsPIC DSC products with embedded CAN controllers. LIN support is integrated into many products for lowcost, single-wire serial communication for automotive applications. The new dsPIC33EV family also includes SENT for automotive sensing. The dsPIC33EV 5V CAN-LIN Starter Kit (DM330018) contains data ports for CAN, LIN and SENT, a self-contained USB programming/debug interface, and an expansion footprint for flexibility in application hardware development. A CAN/LIN PICtailTM Plus Daughter Board (AC164130- 2) is available to plug into the Explorer 16 (DM240001) for developing embedded CAN or LIN applications. This must be used with a processor Plug-In Module (PIM) for a compatible PIC24 MCU or dsPIC DSC product. IrDA® The IrDA standard is an inexpensive method for providing wireless point-to-point communication. Through Application Note AN1071, Microchip’s free IrDA stack is available to support 16-bit MCUs with integrated IrDA support, enabling a cost-effective wireless connection with plenty of computing power left for other tasks. PMBus The PMBus protocol standard operations over an I2C physical layer and was developed to enable easy digital management of power supplies. The protocol allows for reading values from a power supply such as measured voltage and current parameters, temperatures and fan speeds as well as writing commands to control the operation of the power supply. The dsPIC “GS” family of DSCs supports the PMBus protocol along with many other dsPIC DSCs and PIC24 MCUs. A PMBus stack is available free from Microchip for use with the dsPIC “GS” family of DSCs. Wireless Microchip offers a wide range of wireless modules ranging from Wi-Fi®, Bluetooth, Bluetooth Smart and various Personal Area Networks. These fully certified surfacemount modules allow you to quickly and seamlessly add wireless connectivity to your applications. The wireless modules allow you to bypass costly and timely RF design, Bluetooth certification and governmental certifications to get your designs to market faster. For wireless sensors and other battery-operated applications, the eXtreme Low Power PIC24 MCUs are ideal companions to Microchip’s RN4020 Bluetooth Low Energy Wireless Module, creating low-power wireless networks. Together these devices allow for connection to Bluetooth-enabled devices, making it easy to add internet connection to your embedded application for remote command and control. Application Note AN1861 describes the hardware and software needed to pair an XLP PIC24 to the RN4020 Bluetooth Low Energy Module. USB There are many PIC24 MCU and dsPIC DSC families with integrated USB which include support for device, host and On-The-Go (OTG) functionality. These products are supported by the dsPIC DSC USB Starter Kit (DM330012) as well as the Explorer 16 Development Board (DM240001) with USB PICtail Plus Daughter Card (AC164131) and one of the USB Processor Plug-In Modules (PIMs). Microchip’s free USB framework includes USB software libraries as well as a comprehensive set of host and device drivers including Human Interface Device (HID) class for user interfaces, and Mass Storage Device (MSD) class for memory devices as well as CDC, PHDC, custom, audio, printer and demo code including thumb drive bootloader, and printer host. The USB libraries, drivers and demo code are all available with the Microchip Libraries for Applications download. www.microchip.com/connectivity
