Microcontrollers Integrate USB and Large RAMMicrochip Technology Inc., a leading provider of microcontroller, analog, and Flash-IP solutions, offers the four-member PIC24FJ256GB210 microcontroller family, which 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 better overall throughput, for applications such as Ethernet connectivity, remote sensing, data logging, and audio streaming. It can also be used to store generated images or data for dynamic content, such as real-time, remote sensor data graphs. In combination with Microchip’s free USB software library and TCP/IP stack, these MCUs lower system costs and footprints in medical applications.

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.
