A four-member microcontroller integrates USB for Embedded Host/Peripheral/On-the-Go and 96 Kbytes of RAM. This large RAM enables the buffering of sizeable amounts of data and improved overall throughput, for applications such as Ethernet connectivity, remote sensing, data logging and audio streaming. The PIC24FJ256GB210 microcontroller family from Microchip Technology can also be used to store generated images or data for dynamic content, such as real-time, remote sensor data graphs. 

The requirements for embedded designs are rapidly expanding, including the widespread and growing adoption of connectivity and the ability to buffer large amounts of data. At the same time, the pressure to reduce cost and size is constant. Microchip integrates a USB peripheral and large amounts of RAM into a single microcontroller as small as 64 pins, along with Peripheral Pin Select, to provide designers the flexibility to remap digital I/O pins. Additional peripherals include 24 channels of mTouch capacitive touch sensing, along with a free touch software library, and the 16-bit Enhanced Parallel Master/Slave Port, which enables wider peripheral selection and improved bandwidth when connecting to off-chip resources.

This new microcontroller family easily integrates into Microchip’s long-standing, modular development-board system. A new $25 Plug-in Module is available today, which readily connects to the proven Explorer 16 Modular Development Board and its companion USB PICtail Plus daughter card. All four members of the PIC24FJ256GB210 16-bit microcontroller family are available today starting at $4.10 each in 10,000-unit quantities.
