NXP’s exclusive software-driven I/O Handler (IOH) on the LPC11E37HFBD64 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
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.
