NXP LPC11U35FHI33/501, 32bit ARM Cortex M0 Microcontroller, LPC11U, 50MHz, 64 kB Flash, 33-Pin QFN

The NXP family of ARM Cortex-M0 based, low-cost 32-bit MCUs are designed for 8/16-bit microcontroller applications. They offer high performance, low power, simple instruction set and memory addressing together with reduced code size compared to existing 8/16-bit architectures.

32-bit performance in a 16-bit footprint resulting in more power efficiency and longer battery life
Small size enables the processor and analogue circuits to be implemented on single die
Ultra-low power consumption and integrated sleep modes resulting in longer battery life
Thumb® instruction set for maximum code density
