This is the MCU used for the original IOIO. The PIC24FJ256DA206 is a 16-bit flash microcontroller with an embedded graphics controller and USB On-The-Go (OTG) capabilities.
On-board RAM is provided for display buffer, scratch areas, images and fonts. In some cases, the RAM requirements for the display used exceeds the on-board RAM; external memory connected through EPMP can be used. The embedded graphics module provides acceleration for drawing points, vertical and horizontal lines, rectangles, copying rectangles between different locations on screen, drawing text and decompressing compressed data.
The USB On-The-Go (USB OTG) module provides on-chip functionality as a target device compatible with the USB 2.0 standard, as well as limited stand-alone functionality as a USB embedded host.
