MCHP have a 28pin SOIC, 32bitter could be a replacement for the dsPIC since its cheaper. Unfortunately only 40Mhz and limited amount of memory yet I2S and USB. So Mr MCHP why make a 200Mhz, 1Mbyte SRAM version in SOIC, your competitor ST are not far away.. PIC32MX220F032B http://www.microchip.com/wwwproducts/Devices.aspx?dDocName=en556007
