New ‘Easy-to-Use’ USB microcontrollers from NXP target more demanding applications

NXP Semiconductors is making available the LPC11U6x – its newest family of easy-to-use, USB-IF certified USB microcontrollers. The LPC11U6x family builds on the design flexibility of NXP’s LPC11Uxx portfolio with a range of enhanced features, including a more energy-efficient ARM Cortex-M0+ processor, significantly more flash and SRAM, more serial communications, a new 2-Msps ADC and more versatile timers.  These additional features allow the LPC11U6x to tackle a wider range of applications in consumer, commercial and industrial markets such as metering and data collection, wired and wireless routing, handheld medical equipment, and PC/gaming accessories, among others.

The LPC11U6x family includes a USB device controller certified by the USB Implementers Forum (USB-IF) and gives designers access to all the USB software, tools and shortcuts they need to simplify development and reduce time to market. Embedding the USB drivers in ROM cuts design time and shrinks application program footprint while increasing reliability, while an on-chip PHY reduces the solution BOM and design complexity. Furthermore, NXP provides a royalty-free USB device driver stack, extensive example code for popular device classes, and a free PID/VID program which make USB development easy for designers with any level of USB expertise.

“For consumers, USB is synonymous with ease of use. We offer microcontrollers with embedded USB functionality that is just as simple and fast for developers to use — no USB expertise required,” said Ross Bannatyne, general manager, mass market microcontroller product line, NXP Semiconductors. “And with significantly more on-chip memory and connectivity resources, the LPC11U6X offers customers a simple, no-risk solution for USB configuration in a wider range of demanding embedded applications.”

To support more demanding data and buffering requirements, as well as larger application code sizes, the LPC11U6x extends memory options by doubling flash to 256 KB and tripling SRAM to 36 KB. More rigorous I/O requirements are supported by expanded serial connectivity, including 5 USARTs, 2 I2Cs, 2 SPIs, and up to 80 GPIOs, along with a new 12-channel, 12-bit, 2-Msps ADC for higher bandwidth and higher-precision input. New to the LPC11Uxx Series, the LPC11U6x utilizes an ARM Cortex-M0+ core for exceptional power efficiency.

LPC11U6x MCUs also include both standard and configurable timers/PWMs for advanced timing requirements. Higher operating temperatures (up to 105 ºC) make them suitable for more industrial environments.

The LPC11U6x is fully supported by the LPC software ecosystem and an extensive collection of tools, drivers and middleware, as well as popular forums and blogs in constant use by a highly engaged and collaborative community of embedded developers. Free to all LPC11Uxx developers, the NXP LPCXpresso development platform includes a full featured C/C++ IDE and LPCOpen firmware libraries complemented by low-cost target boards with on-board debug probes. LPCOpen incorporates device drivers, stacks, and graphics libraries that enable rapid code development and can be used with a wide range of third-party RTOSs, middleware solutions, and popular third-party ARM development tools including Keil and IAR. LPC11U6x is software- and tool-compatible with existing LPC11U/Exx and LPC134x parts, simplifying migration and end-product planning.
