Microcontrollers add features to ease late design changes

December 06, 2013 // By Graham Prophet
NXP's LPC11E37H and LPC11U37H MCUs feature a new I/O handler functionality to simplify system design changes, offering the flexibility to add incremental peripheral functionality at any point during the design cycle.

The I/O Handler peripheral can be easily configured to add I 2S, I 2C, UART, DMA and other functionality to the MCU with little impact on CPU performance. Each microcontroller features a low-power 50-MHz ARM Cortex-M0 processor with up to 128 KB of flash, 12 KB of SRAM and 4 KB of EEPROM, with an additional Full-Speed USB device controller included on the LPC11U37H.

You can add functionality, such as serial communications interfaces, at any time in the design cycle, NXP says; the I/O Handler can provide DMA (Direct Memory Access) or ADC threshold functionality to further optimise performance and power efficiency.

The I/O Handler is configured using pre-compiled libraries that can be downloaded from NXP’s LPCware software and support website and are available for no additional charge.
