LPC11E37x & LPC11U37x 32-bit Microcontrollers

NXP Semiconductors LPC11E37x and LPC11U37x 32-bit Microcontrollers (MCUs) are Arm® Cortex®-M0 based, low-cost 32-bit MCUs, designed for 8/16-bit applications, offering performance, low power, simple instruction set and memory addressing together with reduced code size compared to existing 8/16-bit architectures. The I/O Handler (IOH) is a software library-supported hardware engine 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, and 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 for multiple I/O Handler applications are available on www.lpcware.com/ioh.
