Flash PIC micros have full-speed USB 2.0 connectivity

Microchip has released the first Flash PIC microcontrollers with full-speed USB 2.0 connectivity and 48 MHz operation, for 12 Mbps data-transfer rates. Combined with a wide variety of peripherals and nanoWatt technology power management, these features provide a complete solution for designers working with USB in industrial, medical and many other embedded applications.
Most USB-capable microcontrollers are optimised for personal computing and consumer applications, rather than embedded designs. This USB PIC microcontroller family offers the benefits of full-speed USB to a broader range of applications that may operate in harsh environments and connect to personal computers less often.
Target applications include the industrial, medical and automotive markets as well as advanced consumer applications and other PC-connected, battery-powered devices. The full-speed USB 2.0 interface featured includes an onboard transceiver and a parallel streaming port for direct data transfers to external peripherals with minimum CPU overhead. Another of the family's key features is its 24 or 32 Kbytes of self-programmable enhanced flash memory, supporting field upgrades via the USB port.
One key consideration for USB-application designers is the availability of firmware support. Microchip offers an extensive set of libraries for the most common application classes, including the human interface device (HID), communication device class (CDC) and custom drivers. Microchip is also publishing an application note illustrating how to replace a serial port with a full-speed USB link in a few easy steps.
The PIC18F2550 and PIC18F2455 come in 28-pin SOIC and SDIP, and the PIC18F4550 and PIC18F4455 come in 40-pin DIP, 44-pin TQFP and QFN.
