New LPC Microcontrollers Optimized for System Design Flexibility

December 05, 2013

NXP LPC11E37H and LPC11U37H feature new I/O Handler functionality to simplify system design changes

Eindhoven, Netherlands and San Jose, California, December 5, 2013 – NXP Semiconductors N.V. (NASDAQ: NXPI) today introduced two new microcontrollers that allow developers to address late design changes to their system. The LPC11E37H and the LPC11U37H include an “I/O Handler” peripheral that offers designers 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 I2S, I2C, 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.

“With design cycles becoming shorter than ever, there are often unforeseen system changes that require additional MCU functionality late in the design,” said Ross Bannatyne, general manager, mass market microcontroller product line, NXP Semiconductors. “The new I/O Handler peripheral allows designers to easily add significant functionality, such as serial communications interfaces, at any time in the design cycle. The I/O Handler can even provide DMA (Direct Memory Access) or ADC threshold functionality to further optimize 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.
