The NXP LPC1113FHN33/201551 is a 32-bit ARM Cortex-M0 microcontroller from the LPC1100 series, clocked at 50 MHz with 24 KB Flash and 4 KB RAM. It integrates 28 general-purpose I/O lines, I²C, SPI, and UART/USART serial interfaces, plus an 8-channel 10-bit ADC. The part operates from 1.8 V to 3.6 V and is rated for -40°C to 85°C, suiting it for industrial sensor nodes, motor-control interfaces, and low-power embedded control in factory or outdoor telecom enclosures.
50 MHz core — throughput for real-time loops
The 50 MHz Cortex-M0 handles a PID loop at several kilohertz or polls multiple UART lines without a dedicated DMA engine.
Memory budget and peripheral set
24 KB Flash and 4 KB RAM fit a modest firmware image — a bootloader, a Modbus RTU stack, and a few sensor calibration tables. The 8-channel 10-bit ADC resolves analog inputs from thermistors or potentiometers; the I²C and SPI buses connect to external EEPROM, digital potentiometers, or MEMS sensors.
The 32-HVQFN (7x7 mm) package with exposed pad aids thermal transfer in enclosed assemblies.
