NXP’s exclusive software-driven I/O Handler (IOH) on the LPC11U37HFBD64 gives designers the ultimate design flexibility to adapt the MCU configuration and functionality to fit application needs at any time during the design cycle. The I/O Handler is a software-driven block supported by software libraries that can be used to add performance, connectivity and flexibility to system designs. The I/O Handler can emulate serial interfaces such as UART, I²C, or I²S with no or very low additional CPU load and can off-load the CPU by performing processing-intensive functions like DMA transfers in hardware.
Software libraries available for the I/O Handler include I²S, I²C, UART, CRC, threshold ADC conversion, and DMA functionality. The libraries can be downloaded at: www.lpcware.com/ioh
It’s easy to get started with the I/O Handler:
In addition, the LPC11U37HFBD64 is equipped with a highly flexible and configurable full-speed USB 2.0 device controller, bringing unparalleled design flexibility and seamless integration to today’s demanding connectivity solutions.
So whether it’s deciding on communication interfaces, accommodating late design changes, or requiring more performance or power efficiency from the application, the I/O Handler gives designers the ability to save time and cost while adding functionality to meet design deadlines.
