NXP LPC11U6x 32-bit ARM Cortex-M0+ MCU

NXP's LPC11U6x 32-bit ARM Cortex-M0+ family builds on the ease-of-use and design flexibility of NXP's award-winning LPC11Uxx portfolio with a range of enhanced features, including a more energy-efficient ARM® Cortex™-M0+ core, 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 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.
