The NXP LPC1113FHN33/302K is a 32-bit ARM Cortex-M0 microcontroller from the LPC1100L series, clocked at 50 MHz. It carries 24 KB of Flash program memory and 8 KB of SRAM, with 28 general-purpose I/O lines and a 8-channel 10-bit ADC. The part is rated for -40 to 85 °C operation, making it suitable for industrial control panels, outdoor telecom enclosures, and factory-floor sensor nodes.
Peripheral set for a control node
I²C, SPI, and UART/USART interfaces cover the common sensor and actuator links — temperature probes over I²C, ADCs over SPI, or a Modbus RTU slave on the UART. The 8-channel 10-bit ADC reads analog inputs like potentiometer positions or current-sense voltages without an external converter. On-chip brown-out detect, POR, and watchdog timer handle supply supervision and fault recovery without external supervisor ICs.
