The NXP LPC11A11FHN33/001551 is a 32-bit ARM Cortex-M0 microcontroller from the LPC11Axx series, clocked at 50 MHz. The 28 general-purpose I/O lines, plus I²C, SPI, and UART interfaces, suit it for compact sensor nodes, motor-control feedback, and industrial I/O modules.
An 8-channel 10-bit ADC and a single 10-bit DAC are integrated, saving board space for analog front-end tasks like reading a potentiometer or outputting a control voltage.
No, the part has an internal oscillator, so no external crystal is needed for basic operation.
The datasheet is available from NXP under the base product number LPC11; it covers the full LPC11Axx family electrical characteristics and register map.
The core runs at 50 MHz, which sets the timing budget for control loops and serial communication baud rates.
