Flexible MCUs enable late system design changes
Allowing developers to address late design changes to their system, the LPC11E37H and LPC11U37H microcontrollers from NXP include an I/O Handler peripheral. The microcontrollers provide designers with the flexibility to add incremental peripheral functionality at any point during the design cycle.
It is easy to configure the I/O Handler to add I2S, I2C, UART, DMA and other functionality to the MCU with little impact on CPU performance. Both the LPC11E37H and LPC11U37H feature 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. The LPC11U37H also includes an additional Full-Speed USB device controller.
Ross Bannatyne, General Manager, Mass Market Microcontroller Product Line, NXP Semiconductors, commented: “With design cycles becoming shorter than ever, there are often unforeseen system changes that require additional MCU functionality late in the design. 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 or ADC threshold functionality to further optimize performance and power efficiency.”
Available for no additional charge, the I/O Handler is configured using pre-compiled libraries that can be downloaded from NXP’s LPCware software and support website.
